Abstract

In order to study of genetic diversity in 35 lentil genotypes in some morphophenological   traits, yield and yield components, and determine the relationships between different traits by multivariate statistical methods, an experiment was conducted as augmented design in 4 blocks in 2012. The results of descriptive statistics showed that many of traits had considerable variability. The results of the simple calculated correlation coefficients showed that harvest index had the greatest effect on seed yield. Stepwise regression analysis showed that traits such as, harvest index, biologic yield and leaf and stem dry weight justifies the most variation of yield. Results of path analysis showed that the highest direct positive effect on yield was related to harvest index. Factors analysis with varimax rotation extracted 6 factors which it described almost 85.9 percent of total variation in the data. Cluster analysis by average linkage method established all genotypes in 3 different groups. The highest diversity was observed between cluster 2 and 3.
