SUMMARY

The conducted study, with focus on the earliness and opening rate of bolls, and other economic traits of introgressive cotton lines, was carried out from 2017 to 2019 at the Institute of Genetics and Plant Experimental Biology, and Genetics and Evolution Biology Department, in Chirchik State Pedagogical Institute, Tashkent, Uzbekistan. Overall, the introgressive cotton lines were found to ripen two to 13 days earlier than a standard cotton cultivar C-6524. Particularly, in line L-РСМ, the vegetation period took 109 days and matured 12.3 days earlier than a standard cultivar check. According to the boll weight, the selected cotton lines were identified to have the best performance, as well as, good germination ability of seeds. The cotton line, Т-138, was found highly resistant to strains of Fusarium oxysporum f. sp. vasinfectum pathogenic fungi, while the lines, L-РСМ and L-138, had 80% to 100% resistance to Verticillium dahliaе fungi. The cotton lines, L-РСМ and L-141, were not infected with Fusarium solani fungi. The cluster analysis revealed that according to the economic traits, the first cluster included lines L-24 and L-138 and were found to be closely related to each other. The line, LРСМ, was included in the third cluster, and it was found that this cotton line was among the cultivars with the best performance for all the valuable economic traits. The comparative analysis of cotton lines resulted in a creation of a new medium-fiber cotton cultivar “Niso,” with the productivity of 3,830 to 5,650 kg ha-1, boll weight of 6.0 to 6.7 g, boll opening at 109.0 to 112.0 days, type IV fiber, 1000seed weight of 118.0 to 120.0 g, fiber percentage ranging from 36.9% to 41.4%, fiber length at 34.0 to 35.9 mm, and relative tensile strength (34.6 cN/tex). Cotton lines obtained on the basis of intergenomic introgression methods were included in the leading “Cotton gene pool” (Reference of the Academy of Sciences of the Republic of Uzbekistan №4/1255-2473 dated November 12, 2020). These introgressive cotton lines made it possible to enrich the collection of cotton, to evaluate wild cotton species, and to form a system of information and analysis of the electronic database of adaptable stress factors and genetically enriched samples.

Summary

Three bacterial isolates selected as plant growth-promoting endophytic bacteria (PGPEB) from “Klutuk” banana (Musa balbisiana L.) gained scrutiny for first-time testing on black rice. The presented study pursued an investigation on the impact of endophytic bacteria inoculation obtained from “Klutuk” banana plants on the growth and production traits of black rice. For this research, the three bacterial isolates (K10, K324, and K111) served as inoculums for black rice seeds, testing for synergism. The three isolates inoculation into black rice plants used both single and consortium inoculation methods. With agar media, black rice growth observation began 14 days after plantation (DAP) while on soil, at 30 and 140 DAP with inoculation. Three isolates did not show any antagonistic reactions. Overall, isolate K10 showed less significant improvement in growth and yield traits of black rice compared with two other isolates, i.e., K324 and K111. With agar media, the endophytic bacteria inoculations did not show a significant effect on the growth of black rice, and even isolate K324 was inhibiting in action. However, on soil media, isolate K324 significantly enhanced the number of roots and shoot length in black rice compared with the control at 30 DAP. The single inoculation with isolate K111 has caused increased productivity based on the weight of the root, dry grain weight per clum, plant height, root length, leaf length, and panicle length in black rice. Isolate K324 promotes the growth of black rice on the soil media at 30 DAP, while isolate K111 improves the production traits on the soil media at 140 DAP. The study findings provide a significant basis for the positive impact of endophytic bacterial inoculation on black rice growth and yield traits.

Summary

A three-way cross is an artificial cross performed to assemble superior cultivars for increased soybean production. The presented study aims to evaluate the percentage of success in the single cross and three-way cross of soybean genotypes to enhance the genetic variability in the base population of the genetic material. The genetic material comprises three soybean cultivars, i.e., Grobogan, Anjasmoro, and Dega-1. The three-way cross design operation made various crosses. Parameters observed were plant morphology, percentage of cross success and seed formation in pods, number of seeds in pod, and the total seed weight. The results showed a relatively high (57.14%) success rate for the cross Grobogan × Anjasmoro, producing numerous one-seeded and two-seeded pods and 30 seeds per plant with a total weight of 5.4 g. However, the success rate in three-way cross (F1 descent [Grobogan × Anjasmoro] × Dega-1) was medium (35.37%). The results of crossing the three genotypes of parents will greatly determine soybean variability.

DIVERSITY OF PITCHER PLANTS (NEPENTHES SPP.) IN RIAU ARCHIPELAGO PROVINCE, INDONESIA

FITMAWATI, SARTIKA, and E. JULIANTARI

Citation: Fitmawati, Sartika, Juliantari E (2023). Diversity of pitcher plants (Nepenthes spp.) in Riau Archipelago Province, Indonesia. SABRAO J. Breed. Genet. 55(3): 927-939. http://doi.org/10.54910/sabrao2023.55.3.27.

Summary

Nepenthes spp. is a unique carnivorous plant with the modified leaf lamina as a pitcher to trap insects. Nepenthes usually produce lower traps near the base of the plant, and upper pitchers form a loop in the tendril, allowing it to wrap around the nearby plant. Pitcher plants, being insectivorous plants, can grow in nitrogen-deficient soils. In the Riau Archipelago Province, the intense land conversion to establish ecotourism in national parks disturbed the pitcher plant habitat, even though the pitcher plants have great potential as ornamental plants. Therefore, for in situ conservation, the existing endemic flora may benefit tourist attractions to support local ecotourism efforts. Based on the above discussion, the presented study aimed to characterize the pitcher plants’ diversity and analyze the relationship among its species using morphological markers in the islands of Bintan, Karimun, and Lingga, Indonesia. Based on the collection and identified pitcher plants, the study discovered that the genus Nepenthes comprises 25 accessions belonging to six different species, i.e., N. gracilis, N. × trichocarpa, N. reinwardtiana, N. ampullaria, N. rafflesiana, and N. × hookeriana. The cluster analysis grouped two main clusters that have a similarity coefficient of 31%–97% based on morphological characteristics among Bintan, Karimun, and Lingga accessions. However, the cluster constructions were more on the traits’ similarity than locality based. For principal component analysis (PCA), 19 morphological traits can benefit as diagnostic features to distinguish the pitcher groups. The study revealed that pitcher plants have diverse phenotypic plasticity in the Riau Archipelago, which is experiencing land conversion for tourism activities. The pitcher plants diversity has the genetic potential for ornamental plants development and is a biological wealth that requires conservation for research, tourism activities, and future generations.

IDENTIFICATION OF PINUS MERKUSII LANDRACE BELONGING TO KERINCI – WEST SUMATRA, INDONESIA, USING SEQUENCE-RELATED AMPLIFIED POLYMORPHISM (SRAP) TECHNIQUE

A.Z.S. RINALDI, NURAINAS, and SYAMSUARDI

Citation: Rinaldi AZS, Nurainas, Syamsuardi (2023). Identification of Pinus merkusii landrace belonging to Kerinci – West Sumatra, Indonesia, using sequence-related amplified polymorphism (SRAP) technique. SABRAO J. Breed. Genet. 55(3): 917-926. http://doi.org/10.54910/sabrao2023.55.3.26.

Summary

Pinus merkusii is a potential wood that naturally grows in Central Sumatra (Kerinci) and North Sumatra (Aceh and Tapanuli), Indonesia. The Kerinci landrace has a different morphology from the other two Sumatran Pinus landraces, namely, Aceh and Tapanuli, but its placement is at the same taxonomic level. Hence, additional characters need evaluation to validate taxa on P. merkusii landrace belonging to Kerinci. This study aims to identify differences in genetic characters between Kerinci and Aceh (Rao and TAHURA [Taman Hutan Raya]) landraces using SRAP for long-term use and future conservation. DNA extraction ran from the leaves of 24 individual trees belonging to three populations of P. merkusii, i.e., one naturally occurring population in Kerinci and the two cultivated populaces found in Rao and TAHURA, Indonesia. Using seven SRAP combination primers, the analysis revealed an immense variety of alleles (bands). Overall, the amplification produced 62 bands, with nine, on average, per primary pair. However, most bands were polymorphic (91.79%), and only 0.57% were monomorphic. With 45% informative bands, the Kerinci landrace has the highest band variation. A combination of primer C (Me1 + Em3) at 900 bp and primer I (Me3 + Em1) at 1050 bp band size indicated specific bands that served as molecular characteristics. A crucial molecular characteristic distinguishes the landraces of P. merkusii found in Kerinci and other populations in Rao and TAHURA, Indonesia. The study revealed superior genetic variation among the P. merkusii populations evaluated.

Conservation and sustainable use of P. merkusii from Kerinci decline due to the reduction. The discovery of molecular characteristics in the form of a combination of primer C (Me1 + Em3) at 900 bp and primer I (Me3 + Em1) at 1050 bp is crucial for recognizing Kerinci pine tree populations and valuable for plant breeders to conserve and develop germplasm.

Summary

Sunflower (Helianthus annuus L.) is a globally prominent oil seed. Sulfur is a vital nutrient that plays a crucial role in the growth and development of crop plants. Compared with other crops, oilseed crops require more sulfur for their role in oil biosynthesis and as an essential constituent of amino acids, vitamins, proteins, and enzyme structure. Its deficiency results in poor utilization of NPK and, ultimately, crop reduction in yield and quality. Hence, the study investigated the effect of different levels of sulfur on the harvest and quality attributes of various sunflower hybrids. The experiment comprised four sulfur levels (0, 20, 30, 40, and 50 kg per ha) and four sunflower hybrids coded as C124 × RH344, C112 × RSIN82, C116 × RH344, and C208 × RH445. The recorded data underwent analysis statistically using Fisher’s analysis of variance technique, and treatment means comparison followed Tukey’s honest significant difference test (HSD) at a 5% probability level. The results showed maximum plant height at maturity (75.80 cm), head diameter (17.90 cm), leaf area per plant (2,309.21 mm2), 100-achene weight (10.60 g), achene yield (2,806.61 kg ha-1), harvest index (26.58%), and oil content (48.46%), while minimum days to flower initiation (40.33 days) were evident when sowing hybrid C124 × RH344 with an application of 20 kg per ha sulfur.

The 20 kg per ha application of sulfur performed best among all sulfur levels and hybrid C124 × RH344 gave superior performance among all four sunflower hybrids. Hence, sowing of hybrid C124 × RH344 with 20 kg per ha sulfur combined with recommended NPK (120–60–60 kg ha-1) improved sunflower hybrids’ growth, yield, and quality.

Summary

The breeding material comprising 17 Iraqi wheat cultivars belongs to three different types, i.e., a) salinity-tolerant cultivars (Dajla, Furat, 1H, 2H, 2N, 3H, 3N, and 7H), b) drought-tolerant cultivars (Sham-6 and Orok), and c) local cultivars (Iraq, Iba99, Iba95, Abu Ghraib-3, Adnanin, Tamoze, and Alrashid) underwent qualitative characteristics and genomic analysis studies in 2021-2022, at the Biotechnology Research Center, Al-Nahrain University, Baghdad, Iraq. Measuring the percentage of protein, wet and dry gluten, and molecular fingerprinting used the randomly amplified polymorphic of DNA (RAPD) technique with six primers, with traits estimation using a dendrogram. The highest percentage of protein (24.5%), wet (52.7%), and dry gluten (27.3%) emerged from the wheat genotype Dajla. However, the recorded lowest percentages of wet (32.52%) and dry gluten (7.62%) appeared in wheat genotype Iba99. The cultivars Aadnania, Abu Ghraib-3, and Tamoze gave the lowest protein content of 9.45, 10.34, and 10.54, respectively. The cluster analysis divided 17 wheat genotypes into two large cluster groups. Amplification of all 365 loci used six primers. Fragments‟ size ranged from 100 bp to 2000 kb. The highest number of bands (73) was amplified with primer Pr-5, while the lowest number (48) was with primer Pr-1.

STATE AND PROSPECTS OF MINERAL FERTILIZERS USE IN AGRICULTURE OF KAZAKHSTAN

S.B. KENENBAEV, S.B. RAMAZANOVA, and V.N. GUSEV

Citation: Kenenbaev SB, Ramazanova SB, Gusev VN (2023). State and prospects of mineral fertilizers use in agriculture of Kazakhstan. SABRAO J. Breed. Genet. 55(3): 886-895. http://doi.org/10.54910/sabrao2023.55.3.23.

Summary

The article is a dedicated analysis of the production and use of mineral fertilizers globally, focusing on the agriculture of Kazakhstan. From 1950 to 2020, the fertilizer use ranged between 3.6–29.0 kg of NPK per hectare in arable agricultural land of Kazakhstan. The maximum benefit of fertilizers happened in 1986 in Kazakhstan, with 1,039 t of mineral fertilizers (active substances) applied at an area of 47% of the total arable land, while in 1965, the fertilized area was only 6.6% of the entire sown field. In Kazakhstan, the annual recommended need for mineral fertilizers is one million tons (active ingredient). The paper also discussed the influence of the long-term application of fertilizers on the leading indicators of soil fertility and crop productivity. Employing regression analysis also explored a high degree of probability of a positive relationship among the four viable factors, i.e., fertilizer use intensity, agrochemical indicators of the soil, crop plants yields, and their quality.

Mineral fertilizers, humus, nutrition elements, agrochemical indicators of the soil, fertilizers’ efficiency, crop productivity

In the agriculture of Kazakhstan, the fertilizer analysis indicates a low level of use. The annual need for mineral fertilizers for the entire sown area of the Republic was 2.5 million t in physical weight (including 1.2, 1.3, and 0.03 million t of nitrogen, phosphorus, and potassium, respectively).

Summary

Camellia is a large genus in the tea family of Theaceae. In this genus, several species serve different purposes, such as, medicinal and ornamental plants and beverage production. Thus, country-wide cultivation of various species of Camellia genus sought to alleviate poverty and promote economic development in many regions. However, studies on evaluating its genetic resources as a foundation for the conservation and development of this plant are yet to start. Currently, using DNA barcoding often serves as a highly reliable approach to identifying and characterizing numerous plants. In the presented study, a total of 10 Camellia accessions collected from Dong Bua village, Tam Quan commune, District Tam Dao, and Vinh Phuc province, Vietnam, underwent study during 2020–2022 at Ho Chi Minh City University of Food Industry, Vietnam. Evaluation of two DNA barcoding regions, namely, rbcL and trnH-psbA, transpired for their ability to distinguish the Camellia accessions belonging to different species in Vietnam. The results revealed a significant difference in the DNA sequences of the rbcL and trnH-psbA regions among the Camellia species. In addition, the trnH-psbA barcode region also showed higher effectiveness versus the rbcL region in recognizing various species of Camellia. The results authenticated the potential of DNA barcoding in the management, conservation, and development of the genetic resources of Camellia in Vietnam.

Camellia species, DNA barcode, identification, rbcL, trnH-psbA

DNA barcodes were found as efficient tools for plant identification; however, the accuracy depends upon the utilized barcode regions. In this study, the trnH-psbA proved superior over rbcL for differentiating Camellia species.

Summary

Examining the overgrowth of dumps, techno-soils, and areas containing waste products of uranium mines is vital for understanding the dynamic features of vegetation cover in technogenic landscapes. The main aim of this study was to investigate variations in the plant species composition and their productivity in dumps and technological areas and the intensity of soil ionizing radiations under varying environmental conditions based on the Shantobe Uranium Deposit, Kazakhstan. The vegetation at the waste dumps and technogenic sites is in the early stages of syngenesis and is representative of pioneer and group-thicket communities. Adverse ecological conditions associated with intense sulfate salinization formation thrive at the technological sites. However, the floristic composition is illustrative of highly resistant species (Calamagrostis epigejos and Phragmites australis) and secondary species. Typically the formation of steppe zone plant communities of Kazakhstan does not occur in these sites. The productivity of the recultivated dump and banks of the former uranium mine is quite high at 120–150 g/m2, which matches the meadow-ruderal communities of Northern Kazakhstan. However, the lowest productivity of 30–37 g/m2 emerged in the non-recultivated and partially processed sulfuric acid heap leaching stacks containing uranium ore, which create exceedingly unfavorable conditions for the establishment of crop plants. Several plant species identified as self-seeding live in partially processed piles of sulfuric acid heap-leaching uranium ores with a sufficient level of resistance to survive in soil with high levels of sulfate-containing salts and ionizing radiation of 1200–1400 μR/hr. These facts can authenticate to consider the possibility of growing these plant species in the artificial grassing of uranium-containing dumps to create herbage.

Shantobe Uranium Deposit, Kazakhstan, technogenic sites, uranium-bearing ores, sulfate-containing salt-resistant plant species, floristic composition, ionizing radiation, recultivated dump

The presented study identified that several plant species have enough resistance to survive and grow well on sulfuric acid heap-leaching uranium ores and soils with high sulfatecontaining salts and ionizing radiation (1200–1400 μR/hr). It confirms the possibility of using these plant species for artificial grassing in uranium-containing soils to create herbage.
