Factor analysis is mainly applied as structure detection method in plant breeding. Ten traits incuding days to flowering, days to end of flowering, duration of flowering, and days to maturity, plant height, pods on main axis, pods per plant, pods length, 1000-seed weight and seed yield were studied in 24 rapeseed genotypes based on randomized complete block design.The results of analysis of variance indicated significant genetic variation among the genotypes.On the basis of minimum eigenvalue, four factors were detected for these traits. The eigenvalues for factors from one to four were 3.99, 2.32, 1.17, and 1.06, respectively. The cumulative variation related to these factors was 0.86.The results of factor analysis exhibited four factors including sink factor (pod per plant, pods length and seed yield), fixed capital factor (phenological traits), secondary fixed capital factor (duration of flowering), and metric factor (plant height).therefore the studied genotypes had more variation for yield components.
