(CK)和施P,O,150kg/hm(Piso)两个处理条件下,对不同品系油菜磷素籽粒生产效率进行配合力和遗传参数分析。结果表明,磷素籽粒生产效率(PUEs)杂交组合平均值在Pis和CK处理中分别比亲本平均值高6.41%和 7.64%。离中亲优势的正向组合数明显多于负向组合数,超亲优势的正向组合数(超高亲)明显多于负向组合数(超低亲),表明PUEs存在杂种优势。PUEs的遗传参数在Pisn处理和CK处理中一般配合力方差相对较小,特殊配合力相对较大,PUEs遗传以非加性效应(显性效应及上位性效应)为主。在两个肥力水平下,品系9(ZS-3)的一般配合力较高,6×20(SY07×湘05499)、13×20(NY-14×湘05499)、14×21(湘05487×YY-7)三个组合的特殊配合力较高。

Abstract: In this study, the heterosis and genetic parameters of phosphorus use efficiency for seed production(PUEs) of rapeseed (Brassica napus L.) were investigated using two -factors split experiment.Twenty two parental cultivars (17 female and 5 male parents) and their 17 × 5 = 85 F, hybrids were grown in soils applied P O, 150 kg/ha and without P, Os application (CK). The results showed significant heterosis in hybrids in PUEs . The PUEs in hybrids increased by 6. 41% , 7. 64% respectively in comparison with parents under CK and P iso treatment. Positive heterosis of mid-parent values (H.) in PUEs are significantly higher than negative H,, and positive supe high heterosis are significantly higher than negative super low parents . The general combining ability (GCA) variance in PUEs is relatively small, the specific combining ability ( SCA) variance is relatively large, and the PUEs is mainly controlled by dominance and epistasis effects . The GCA of inbred line 9 (ZS -3) and SCA of 6 × 20 (SY07 ×Xiang 05499),13 ×20(NY-14×Xiang 05499)and 14 ×21(Xiang 05487× YY7) are relatively high under two fertility levels.
