白菜薹主要数量性状的选择及与单株产量的关系研究
|
摘要
通过相关分析、逐步回归和通径分析,探讨了白菜薹(Brassica campestris ssp.chinensis)15个数量性状的选择与单株产量的关系。结果表明,要选育单株产量高的白菜薹品种,除了注重直接作用较大的单薹重、薹数、株幅等性状选择外,还应加强间接作用较大的叶片数和株高等球性的选择,协调好薹粗、薹长与单薹重、薹数的关系也有利于提高单株产量。
Through correlation analysis,stepwise regression analysis and path analysis,the relationship between the selection of 15 quantitative traits and yield per plant of flowering Chinese cabbage was analyzed.The results showed that in order to breed flowering Chinese cabbage(Brassica campestris ssp.chinensis)cultivar with high yield per plant,firstly the selection of single flowering stalk weight,flowering stalk number and plant size should be pay attention.The selection of leave number and plant height with larger indirect effect should be strengthened too.Coordinating the relationship between flowering stalk diameter,flowering stalk length and single flowering stalk weight and flowering stalk number is beneficial for increasing yield per plant.
