Cotton introgressive lines assessment through seed cotton yield and fiber quality characteristics

B. AMANOV, K. MUMINOV, S. SAMANOV, F. ABDIEV, D. ARSLANOV, and N. TURSUNOVA

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.

Response of sugar beet to sandy soil amended by zeolite and potassium sulfate fertilization

H.E.A. NEMEATA ALLA and S.A.M. HELMY

SUMMARY

Two field experiments were carried out on a private farm at Wadi El-Natrun (latitude of 30.48° N and longitude of 30.50° E), Beheira Governorate, Egypt, in the 2019–2020 and 2020–2021 seasons, to find out the effect of adding zeolite as a soil conditioner and potassium fertilizer on growth, yield, and quality of sugar beet crop (Beta vulgaris L. var. saccharifera) grown in sandy soil conditions. The present work included 12 treatments, which were the combinations of four zeolite levels (Zero, 476, 952, and 1,428 kg ha-1), and three levels of potassium in the form of potassium sulfate (119, 178.5, and 238 kg K2.SO4 ha-1), which were added as a soil application. The treatments were arranged in a complete block design in a split plot with four replications. The results showed that higher values of the photosynthetic pigments, root diameter, fresh and foliage weights plant-1, as well as, sucrose and extracted sugar percentages, quality index, yields of the root, top, and sugar ha-1, were obtained by adding 1,428 kg zeolite, compared with the other levels of zeolite, in both seasons. However, sodium, alpha-amino N contents in the root, and sugar lost to molasses% were insignificantly affected by zeolite rates in both seasons. Application of 238 kg K2.SO4 ha-1significantly resulted in the highest values of photosynthetic pigments, root dimensions, sucrose%, and root potassium content. In addition, extracted sugar %, quality index, root, top, and sugar yields ha-1 were increased compared with the other lower K-sulphate levels in both seasons. On the contrary, sugar lost to molasses% was insignificantly affected by applied potassium sulfate in both seasons. The maximum values of root diameter, fresh weight, yields of root and top ha-1 in both seasons, and also sugar yield in the second season were produced from the interaction between applying 1,428 kg zeolite and 238 kg potassium sulfate ha1.

Agronomic responses of diverse bread wheat genotypes to phosphorus levels and nitrogen forms in a semiarid environment

Swailam MA, Mowafy SAE, El-Naggar NZA, Mansour E

SUMMARY

Increasing wheat production has become an urgent requirement to cope with rapid population growth and abrupt climate change. The management of phosphorus (P) and nitrogen (N) is one of the most important factors for sustaining and increasing wheat production, particularly in semiarid environments. This 2-year field study, which aimed to investigate the effect of P levels (0, 35, and 70 kg P2O5 ha−1) and N forms (urea, ammonium sulfate, and ammonium nitrate) on the yield attributes of three diverse highyielding commercial wheat cultivars (‘Shandawel-1’, ‘Sids-14’, and ‘Sakha-95’), was carried out at Om-Elzain Village, Zagazig, Egypt. The results indicated that increasing P levels was accompanied by a substantial increase in all evaluated traits, except spike length, and that high P level (70 kg P2O5 ha−1) was superior. Considerable genetic variation was detected among the evaluated cultivars for all studied traits. Cultivar ‘Sakha-95’, followed by ‘Sids14’, presented the most vigorous growth and enhancements in most yield components, grain yield, and biological yield. Furthermore, ‘Sakha-95’ recorded the highest agronomic P use efficiency, followed by cultivar ‘Sids-14’. N forms did not significantly affect all of the tested traits except plant height, spike number m−2, and 1000-grain weight, during both seasons. Ammonium-containing fertilizer (ammonium sulfate and ammonium nitrate) resulted in the highest values for these traits when compared with urea. Accordingly, ‘Sakha-95’ and ‘Sids-14’ are recommended for commercial use under high P levels. N forms had a marginally substantial effect on grain yield and its attributes.

Validation of molecular markers linked to cercospora leaf spot disease resistance in mungbean (Vigna radiata [L.] Wilczek)

Papan P, Chueakhunthod W, Poolsawat O, Arsakit K, Tharapreuksapong A, Tantasawat PA

SUMMARY

Cercospora leaf spot (CLS) resistance is a highly desirable trait for mungbean (Vigna radiata [L.] Wilczek) production in Thailand. ‘V4718’ is a vital resistance source that shows high and stable resistance to CLS disease. A previous study identified a major quantitative trait locus (QTL) (qCLSC72V18-1) controlling CLS resistance and found the marker (I16274) that was located closest to the resistance gene by using F2:9 and F2:10 recombinant inbred line populations derived through a cross between ‘V4718’ and the susceptible variety ‘Chai Nat 72’ (‘CN72’). Here, we evaluated three newly reported simple sequence repeat (SSR) markers and one InDel marker together with six previously identified markers that were linked to qCLSC72V18-1 to further identify the markers that were located close to this QTL. By performing bulk segregant analysis on two validation populations, we found that two SSR markers (Vr6gCLS037 and Vr6gCLS133) and one InDel marker (VrTAF5_indel) were putatively associated with CLS resistance. Of these markers, only the VrTAF5_indel marker showed a significant association with the CLS resistance gene with a logarithm of odds score > 3 across the phenotypic data for 2016 and 2018. QTL analysis with inclusive composite interval mapping revealed that the VrTAF5_indel marker was integrated into the genetic map with other previously identified markers. The I16274 and VrTAF5_indel markers flanking the QTL of interest accounted for 41.56%-60.38% of the phenotypic variation with genetic distances of 4.0 and 5.0 cM from the resistance gene, respectively. Both markers together permitted only 0.40% recombination with the CLS resistance gene in markerassisted selection and thus could be useful in future breeding efforts for CLS resistance in mungbean.
