中浙优1号产量性状与产量的相关、回归及通径分析

为进一步发挥杂交水稻中浙优1号的增产增效潜力,笔者分析了不同产量水平下,中浙优1号作单季晚稻栽培的穗、粒、重结构,利用相关、回归及通径分析的方法,研究提出了单季杂交晚稻中浙优1号高产高效栽培的技术途径:在一定的有效穗数的基础上,主攻每穗实粒数与千粒重.

Correlation,Regression and Path Analysis between Yield Traits and Yield of Zhongzheyou 1

In different yield levels, the constitutions of panicle, grain and grain weight of Zhongzheyou 1, a single cropping late paddy, were analyzed. Methods of correlation analysis, regression analysis and path analysis were used to promote high-yielding and effective cultivation techniques as follows: besides necessary panicle amount, the direction is grain number per panicle and grain weight of one thousand grains.
