本文应用线性回归和相关分析的方法，研究了榨菜胞质雄性不育系ＣＭＳ９２－６３产量构成因素及真相关性。结果表明，ＣＭＳ９２一６３不育系的单株种子产量平均７．１７８ｇ，比其保持系高１６．５８％。种子产量与主花序有效长度（ｒ＝０．６８５５），二次分枝数（ｒ＝０．６９２６），单株花数（ｒ＝０．７０４６），单株果数（ｒ＝０．７８０２），秸杆重（ｒ＝０．６４２７），单株种子数（ｒ＝０．７７７５）之间呈显著或极显著正相关。建立了榨菜胞质雄性不育系及其保持系单株种子产量的多元线性回归方程。提出增加种子产量的潜力在于提高座果率和单果种子数
In this paper, linear regression and correlation analysis methods to study the tuber mustard CMS CMS CMS yield and true correlation. The results showed that the average seed yield per plant of CMS92-63 was 7.178g, which was 16.58% higher than its maintainer. (R = 0.6855), the number of secondary branches (r = 0.6926), the number of flowers per plant (r = 0.7046), the number of fruit per plant (r = 0.7802 ), Straw weight (r = 0.6427), the number of seeds per plant (r = 0.7775) was significantly or very significantly positive correlation. A multiple linear regression equation was established for the seed yield of tuberous cytoplasmic male sterile line and its maintainer line. The potential for increasing seed yield is to increase fruit set and fruit number
