Indices and multivariate statistics

Variations in the population of lancelets inhabiting Chabahar Bay were surveyed statistically. Multivariate analysis of the Iranian Branchiostoma population using 5 morphometric characteristics indicates no separation of populations by locality in the study area (ANOSIM global; R = 0.2). Principal component analysis of the mean values of the 5 meristic characteristics of the present population with those of conspecifics of other populations around the world showed that Iranian lancelet populations are very similar to B. lanceolatum and completely different from the B. arabia and B.

An experiment was undertaken by utilizing forty five Niger genotypes for twelve yield and yield contributing characters to assess genetic divergence. The analysis of variance has shown that there was significant variation among the genotypes in all the traits. The multivariate analysis carried out using MahalanobisD2 -statistics, indicated wider genetic diversity in the genotypes of niger.

Castor genotypes (30) were evaluated for ten yield and yield attributing characters to study the genetic diversity existing among them by using Mahalanobis D2 statistics. Analysis of variance revealed significant difference among genotypes for all the ten character studied. Based on the D2 values the genotypes were grouped into six different clusters. Maximum inter cluster distance was observed between III and VI (6170.49) while, lowest divergence was noticed between clusters I and II (742.
