A range of environmental factors restricts the production of chickpea; therefore, introducing compatible cultivars to a range of environments is an important goal in breeding programs. This research aims to find high-yielding and stable chickpea genotypes to rainfed condition. Fourteen advanced chickpea genotypes with two control cultivars were cultivated in a randomized complete block design in four regions of Iran during 2017–2020 growing seasons. The first two principal components of AMMI explained 84.6 and 10.0 % of genotype by environment interactions, respectively. Superior genotypes based on simultaneous selection index of ASV (ssiASV), ssiZA, ssiDi and ssiWAAS were G14, G5, G9 and G10; those based on ssiEV and ssiSIPC were G14, G5, G10 and G15 and those based on ssiMASD were G14, G5, G10 and G15. The AMMI1 biplot identified G5, G12, G10 and G9 as stable and high-yielding genotypes. Genotypes G6, G5, G10, G15, G14, G9 and G3 were the most stable genotypes in the AMMI2 biplot. Based on the harmonic mean and relative performance of genotypic values, G11, G14, G9 and G13 were the top four superior genotypes. Factorial regression indicated that rainfall is very important at the beginning and end of the growing seasons. Genotype G14, in many environments and all analytical and experimental approaches, has good performance and stability. Partial least squares regression identified genotype G5 as a suitable genotype for moisture and temperature stresses conditions. Therefore, G14 and G5 could be candidates for introduction of new cultivars.
Lentil (Lens culinaris), with its ability for nitrogen fixation, maintaining soil moisture and limiting soil erosion helps in increasing soil fertility. In order to compare and classify of 14 lentil genotypes, an experiment was carried out in the randomized complete block design with three replications during the cropping year of 2011-2012. Analysis of variance indicated remarkable diversities among genotypes under study and significant differences were obtained for seed yield, biological yield, 100-grain weight, number of the pod with couple seed and rain efficiency. Mean comparisons also showed the genotype G10 was the best genotypes for seed yield, biological yield, the pod with couple seed and rain efficiency, so this genotype is advisable for culture by farmers. As the per principal component analysis, first five principal components expressed 83% of total variation in which PC I, PC II, PC III, PC IV & PC V accounted for 41%, 14%, 12%, 8% and 6% of total variation, respectively. Cluster analysis, based on the traits studied, using euclidean distance following Ward's method with euclidean distance divided the genotypes into three groups and the maximum distance was between cluster I and III. Thus the genetically diverged genotypes of the clusters could be used as the parent in hybridization program to get desirable genotypes. It can be concluded that there is remarkable genetic variability among studied lentil genotypes, which could be utilized in the screening of desirable parents and genotypes for lentil breeding programs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
