ارزیابی تنوع ژنتیکی و گروه‌بندی ژنوتیپ‌های نخود (Cicerarietinum L.) کابلی تحت شرایط تنش خشکی انتهای فصل

In order to evaluate genetic diversity and determine genetic relationship of 64 Kabuli chickpea genotypes under late season drought stress, an experimental design was carried out in a simple lattice design (8×8) in 2011 on the research field of college of Agriculture and natural resource of Tehran University. Based on factor analysis, four factors were selected that in total 81 percent of the total variation was explained. The first and second factors were explained 64 percent of variation that including yield and yield component traits. Therefor these two factor used to identify genotypes with high yield and yield components and genotypes 2, 12, 22, 23, 36, 109, 120, 139, 187, 308, 335, 345, 357, 375, 474, 534, 563 and 629 with two control genotypes Jam (998) and korosh (999) were selected as high yield and component yield genotypes. According to the result of cluster analysis based on morphological traits, the genotypes were classified in 4 clusters. The genotypes of third and fourth cluster in most of agronomic traits and grain yield per plant had high average in compare with other clusters and genotype average. According to result of cluster analysis, we can use third and fourth cluster genotypes and two control genotypes (jam and korosh) for produce hybrids with early maturity and high yield.
