摘要
[目的]为建立甘蓝型油菜理想株型,系统分析了油菜主要农艺性状与产量构成因素间的相关性.[方法]2017-2019年度连续2年试验种植600份来源于主要生态区域的甘蓝型油菜种质资源材料,采集主要农艺性状指标,分析各性状与实收产量间的相关性.[结果]油菜一次分枝数、主序角果数、单株产量与实收产量间呈直线回归关系,其余性状与实收产量间呈一元二次回归关系,且各性状与产量间均呈极显著正相关.角粒数对单株产量和实收产量的贡献最大.[结论]依据各性状与实收产量间的回归关系求极值,得出其理想株型,理想单株产量约为24.21 g,理论产量可达314.73 kg/667 m2.
Abstract
[Objective]To obtain the ideotype of Brassica napus,the correlation between main agronomic traits and yield components was studied.[Method]From 2017 to 2019,600 germplasm resource materi-als from major ecological areas were planted for two consecutive years,and main agronomic traits were collected to analyze the correlation between each trait and actual yield.[Result]The results showed that,there was a linear regression relationship between primary branch number,main sequence pod number,yield per plant and actual yield,and a quadratic regression relationship between other traits and actual yield.All the exhibited a significant positive correlation with yield.Among them,the number of seeds per pod contributed the most to the yield per plant and the actual yield.[Conclusion]According to the regression relationship between the traits and the actual yield,an ideotype was obtained.The yield per plant for this ideotype was about 24.21 g,with a theoretical yield was 314.73 kg/667 m2.
