Summary

Cowpea is one of the crops that have a lot of potential to be utilized as raw food resource in the Southwest Maluku district. The objective of this study was to evaluate local cowpea cultivars from Southwest Maluku under different locations based on morphological characters. The research was conducted in Ambon and Bogor using randomized complete block design (RCBD) with three replications. As many as seven local cultivars and three cultivars from ILETRI were evaluated. Observations were conducted on 18 morphological characters. The results showed that morphological characters were significantly affected by cultivars on each location. In general: KM3, KM4, and KM6 cultivars have the highest value in some morphology characters. Correlation analysis showed a significant correlation between the number of nodes with number of leaves followed by seed number plant-1 with seed weight plant-1 and loci number pod-1 with seed number pod-1 . Principal component analysis showed that there were nine principal components and clustering in two clusters. The local cultivars have the highest genetic potential in this study and could be selected as plant materials in future plant breeding program.

Key words: Different environments, local cowpea, Southwest Maluku, morphological characters

Key findings: Cowpea cultivar KM3 was the best genotype at both locations i.e., Ambon and Bogor, Indonesia. It also showed similar stability in some characters and almost equal with cultivars from ILETRI in these locations.

Summary

Against the background of a changing climate, water logging is a major problem for sugarcane production and results in reduced productivity. Various sugarcane genotypes cultivated in waterlogged areas show different acclimations of yield component traits. Understanding such traits under these conditions could be useful in the selection of suitable sugarcane cultivars. Therefore, the objectives of this study was to evaluate cane yield and millable cane, stalk weight, stalk length, and sugar yield of 12 sugarcane varieties in upland (short water logging period) and lowland (long water logging period) areas. Yield, sugar yield, stalk length, stalk diameter, millable cane, and weight per stalk were measured at 12 months after planting. Under both conditions, the tested sugarcane genotypes were differed in terms of yield, millable cane, single stalk weight, stalk length, stalk diameter, and sugar yield. Long water logging periods induced cane yield reduction and decreased single stalk weight. KK3, Kps01-12, and TBy28-0941 showed consistently high productivity across short and long water logging conditions. A positive correlation between single stalk weight and cane yield was existed, and this trait could be used as criteria selection for high productive cultivars under flooding conditions. Millable stalk number could also be used as a surrogate trait under these conditions.

Key words: Single stalk weight, millable cane, stalk length, flooding, sugar yield

Key findings: The twelve sugarcane genotypes used in this study were significantly differed in terms of yield, yield components, and sugar yield under short-term and long-term water logging conditions. Long periods of water logging result in lower cane yield, sugar yield, single stalk weight and stalk length compared to those obtained under short-term water logging. Single stalk weight contributes to high cane yield and could be used as a selection characteristic for improving cane productivity under water-logged field conditions.

Summary

High production of rice is closely related to high yield component characters namely the number of filled grains per panicle or the density of grains per panicle. These characters are complex and greatly determine yield. These traits are also controlled by many genes whose expression is influenced by environmental conditions. This research aims to study genetic diversity and inheritance patterns of rice yield characteristics in the F4population and to obtain the best genotypes from the selection. The materials in this research were 190 F3 generation seed numbers from the pedigree selection which consisted of 24 field numbers resulting from single crosses between local varieties (Bugis and Sriwijaya) with both IR7858-1 and IR148 (N22) that are tolerant to drought. Our research used an augmented design with four parents as check varieties. The research showed that the grain yield of F4 populations was polygenic and controlled by additive gene actions. The heritability value and coefficient of genetic diversity for grain yield were classified as moderate and high. The intensity of differentials selection by 10 percent based on the grain weight/hill, increased the middle value of other observed characters, like panicle length by 20.9%, the total number of grain by 48.4%, the filled grain number per panicle by 59.7%, and grain weight/hill by 40.9%. However, it decreased percentage of empty grain/panicle by 87.6%. Selection on higher filled grains and dense panicles, regardless of panicle length should be considered for developing the new plant type for upland rice with high yield.


Key words: Grain yield, F4 population, heritability, genetic variability

Key findings: Studying the inheritance systems of characters to form the desired character is an important step in segregating populations. Selection based on high grain yield in the F4 generation is expected to be significant in the development of high yield new type of upland rice.
