摘 要: 对甘蓝型油菜DH系群体多点重复种植进行试验,通过对考种数据的收集、整理、分析和总结,找出几个农艺性状对产量的影响和大小,以及相关性状间的联系。结果表明:该研究条件下,对单株产量贡献较大的前几个农艺性状依次是:千粒重>一次有效分枝数>角果粒数>株高>主花序角果数>主花序长度。
关 键 词: 作物遗传育种;甘蓝型油菜;农艺性状;产量

Abstract: By growing the DH series of Brassica napus L.repeatedly, the paper collects test data and performs collation, analysis and summary to the data for identifying the effects of several agronomic traits on the yield, as well as the correlations among related traits. The results showed that: under the research conditions, the traits having high contributions to plant yield are: thousand seed weight> an effective branch number> pod grains> plant height > main inflorescence pods > length of main inflorescence.
Key words: crop genetics breeding; Brassica napus L.; agronomic traits; yield
