And 402S has thedouble- low (low erucic acid and low glucosinolate) quality like its original parents.展开更多

The results of identification test showed that anong 47 combinationsyielding over the control Xiangyou 15, 17 ones with 402S and 3 ,ones with Xiangyou 91S overyielded more than 20 %, reaching the significant level of 1%; and among 51 combination s yielding overt heir corresponding higher yield parents, 18 ones with 402S and 9 ones with Xianyou 91S oveeryelded at 5 % or 1% significan: level The test for the GCA effect of all parents indicated t hat 402S possessed a stronger combining ability than Xiangyou 91S on yield, siliquae of main inflorescerce, total siliquae per plant, seed yield of single plant and 1000 - seed weight. 10 testcrosing lines with high GC A wer picked out for next testcrosses. Among 8 agronomic traits, total siliquae per plant and seed yield of single plant were regiarded as the key selecting indexes according to the correlation analsis between yield and the agronomic traits on heterosis and on the GCA effect of all展开更多
