Abstract:
In order to study of genetic variation in cultivars and landraces of chickpea a trial consisted of 26 genotypes of chickpea(ciceraaritinum.l) for one year(1393) in framework of completely randomized bloak design with 3 replcation were evaluated at the experimental field soil and water Koohin.The results of ANOVA showed that there were significant differences among accessions for the studied traits expected for biological yield which reveald genetic variation for different traits.The results of comparing the mean of the Genotypes related to the trait of yield (kg/hac)", showed that genotype number 66 (3101ardabili) had the highest function traitand genotype 82 (3240Varamin) had the lowest amont yield respectively. According to the results of phenotypic correlations,trait yield per plant and total yield with the studied ofen traits had significant differences.Stepwise regression for selection of traits related to yield of the seed indicated that weight pod, plant height, number of pods 2 twins explained 87 percent of to tal varation. The result of path analysis indicated that plant yield and biological yield had the greatest direct effect on seed yield respectively.. The results of cluster analysis with Ward's method genotypes were grouped in five clusters.that the genotypes of 65 (3099ardabili) and 66 (3101ardabili) as the best genotypes yielded in the five groups and genotypes of 15 (Kermanshahi) as the least the yielded genotypes in the tree grouping. The results of the analysis in to the principal components showed that there were five main components selected that in total, they explained %87 of total variation, respectively.Factor analysis showed that five factors: yield components, seed characteristics, plant morphology, precocity and plant height that explained 87% of total variation.
