RT - Journal Article T1 - Cytogenetic diversity in the populations of Coriandrum sativum L. of Iran JF - MGJ YR - 2016 JO - MGJ VO - 11 IS - 2 UR - http://mg.genetics.ir/article-1-1418-en.html SP - 197 EP - 206 K1 - Cluster analysis K1 - Coriandrum sativum L. K1 - Karyotype K1 - Variance analysis AB - To study the cytogenetic diversity of 12 populations of Coriandrum sativum L. of Iran, squash technique and hematoxylin staining were used. In order to analyze the obtained Karyotype features, variance analysis in a completely randomized design with 3 replicates, the mean characteristics comparison using Duncan's test (at possibility level 1%), factor analysis with principal components analysis, cluster analysis in Ward method with standard Z-scores and analysis of variance comparing the characteristics mean between groups of cluster analysis, was performed. The results of Karyological study of tip root samples showed that basic chromosome number in all populations studied were x=11 and the number of chromosome were 2n = 2x = 22. In terms of Ploidy level, all populations were diploid. Among all total chromosome length (TL), long arm (LA), short arm (SA), difference between the relative length (DRL), relative length of the shortest chromosomes (S%) and the Asymmetry index between chromosomes (A2), there was a significant difference 1%. About percentage of the general shape of karyotype (TF%) and the relative length percentage of long arm (L% ) there was a significant difference in the level of 5%, which confirms the chromosomal diversity in studied populations. Cluster analysis of populations based on the characteristics of the karyotype were classified them into 3 groups. The greatest similarity was found between the two populations of Nishapur and Hamedan and the least similarity was found between the two populations of Ardebil, and Arak. The results of variance analysis of clusters showed that all traits except SA showed significant differences between the groups. Populations of Nishapur, Arak, Markazi, Mobarakeh, Najaf Abad and Hamedan in the first group in terms of CI, r-value, % TF and % S had the highest values that confirmed symmetrical karyotypes of this group. The populations Isfahan, Qazvin and Nahavand 2 in the second group in terms of characters were placed between the first and third levels. Populations of Malayer, Nahavand 1 and Ardebil in the third group in terms of the traits of chromosome length (TL, LA, SA, AR, DRL,% L) and indicators of asymmetry (A1, A2, AI) had the maximum values which shows the asymmetry karyotypes of this group.
