چکیده

to study of genetic diversity of rapeseed genotypes using multivariate methods under normal and drought stress conditions, 16 genotypes were evaluated using a randomized complete blocks design with three replications in razi university in 2007-08 cropping season. factor analysis under normal condition showed that nine factors explained 89.05 percentage of total data variation, and under drought stress condition showed that eight factors explained 86.05 percentage of total data variation. path analysis for oil yield based on selected traits and stepwise regression showed that two traits including proline in early flowering stage and plant height in middle flowering stage under normal condition and plant height in end of flowering stage and pod length under drought stress condition were selected. cluster analysis based on all traits under normal condition using ward method showed that genotypes were placed in three groups and there was highest genetic distance between sunday and shiralee. under drought stress condition the genotypes were located in three groups using upgma method and the highest distant was observed between sahara and shiralee, thus predict that hybridization of sahara and sunday with shiralee could provide best hybrids and supply a desirable genetic diversity in segregated generations for breeding programs.
