Abstract

In order to CYTOGENETICally study some species of Vetch genus, karyotypes of 14 genotypes from 11 species were analysed by using VIDEO ANALYSIS SYSTEM. According to basic chormosme number, the species were classified in 3 groups of: X=5 (in one diploid genotypes), X=6 (in three diploid genotypes) and X=7 (in ten diploid genotypes). According to Stebbins' categorization genotype 5387 was classified in symmetric class of 3B, genotypes 7075, 312, 1564, and 7456 were classified in 2A, while the others were arranged in 3A. Based on inter and intra chromosomal variations, V.faba which has the most asymmetric and evolutionary karyotypesis classified in the B class. Using the biplot of genotypes, based on two parameters of A1 and A2, and symmetry types of Stebbins, the same results were obtained. The results of analysis of variance based on a completely randomized design indicateda significant differences among genotypes for all traits (P<%1). Using PRINCIPAL COMPONENT ANALYSIS, the first two components justified %95.26% of total variance. In the first component, the arm ratio, lengh of long arm, total length of chromosome, centromer index and total form percentage which had the highest coefficients of eigenvalues, was the most important traits. In the second component, the length of short arm had the most important role for total variation. By cutting dendrogram resulted from CLUSTER ANALYSIS (Ward) in metric distance of 2.52, the genotypes were classified into three groups. The furthest distances were obtained between V.faba and ecotypes of V.villosa that indicates the least affinity between them. The shortest metric distance values were obtained between the two ecotypes of Vervilia (1564) and (7075).The diagram of genotypes dispersion, based on two first components, grouped the genotypes in three separated classes, which is in confirmation with the results of CLUSTER ANALYSIS.
