Abstract: Variance components and the stability of yield characters of rape cultivars or lines tested in Zhejiang rape regional trials in 2008 and 2009 were analyzed with the analysis methods for unbalanced data from regional trial of crop variety. The results showed that the yield was mainly affected by the location and interaction between year and location. The yield of line ‘037-77’ was higher than those of the others but there was no significant difference with that of the control (‘Zheshuang 72’). Except for ‘Zheza 0603’ and ‘Qianza 2630’, which were sensitive to environmental composite indexes, and ‘J6’ and ‘ZY-10’, which showed poor identity, the other cultivars or lines showed similar stability.

Key words: rape, crop regional trial, yield, stability analysis
