Factor analysis for grain yield and other attributes in bread wheat

In order to evaluate grain yield potential in bread wheat genotypes in drought condition, study of relationship between quantitative traits with grain yield and selection of best genotypes for breeding program in near future, 245 genotypes received from CIMMYT (Mexico) with live control genotypes were evaluated in an agment experiment in seed and plant improvement institute Karaj in 2002- 2003. Results of data analysis showed significant differences between genotypes for most of traits. Based on factor analysis via principle component basis eign values five factors explain 67.70 % of data total variance. Also factor analysis showed length of peduncle, extnlsion peduncle length, height and relevant traits to early maturity (heading and dayes to maturity) were important for selection of appropriate genotypes in drought condition.
