Abstract

Cytogenetic studies were performed on 17 populations of 10 ATRIPLEX species. The video image analysis system was used for determining KARYOTYPE species. The basic chromosome number was X=9 for all of the populations but their ploidy levels were varied. On the basis of Stebbins’ method, all of populations were placed in symmetric class of 1A, that indicated the symmetrical KARYOTYPE (considering inter chromosomal and intra chromosomal). The Results of analysis of variance based on completely randomized design (CRD) proved that there were significant differences among genotypes for all traits (p<%1). Using PRINCIPAL COMPONENT ANALYSIS, the first two components justify %98.75 of total variance. In the first component, length of the short arm and total length of chromosome had the highest coefficients of eigen vectors. In the second component centromer index, total form percentage, arm ratio and length of the long arm were the most important part in creating of total variance. By cutting dendrogram resulted from CLUSTER ANALYSIS (Ward) in distance 2.87, the populations classified to four classes. The highest metric distance obtained between A.aucheri and A.halimus. There was the lowest distance between A.leucoclada (Yazd) and A.nitens (Haraz1). The diagram of the populations distribution, based on two main components, classified the populations in four separated classes, which was in agree with results of claster analysis. The results of CLUSTER ANALYSIS (UPGMA) based on 2 parameters (A1 and A2) in distance 1.83, the populations classified to three classes. The highest distance was obtained between A.aucheri and A.lentiformis (Yazd) which imply the lowest affinity between them. There was the lowest distance between A.micrantha and A.tatarica.
