Abstract

In this study, 40 genotypes and breeding lines in the vegetative stage was conducted in a factorial
arrangement based on a complete randomized block design with 3 replications in greenhouse at Sari University
Agricultural Science and Natural Resource, Iran, 2008. Seventeen genotypes were selected and tested in seedling
stage in 2009. The results showed that genotypes had significant difference for all traits. GMP and STI were
suitable indices to ensure good stability and performance evaluation of genotypes in stress conditions. Results of
correlation analysis showed that MP, GMP, MH and STI had high significantly with yield in non stress and
stress conditions. Factor analysis showed that 4 factors explain 86.89% of variation in seedling stage.
