优质杂交稻新组合绵5优527的产量构成因素分析

Yield Component Analysis of “Mian5you527”—a New Hybrid Rice Combination with Fine Quality

运用相关、通径分析的方法分析了四川省优质水稻新组合绵 5优 5 2 7的产量构成因素之间的关系 ,并得出了其主要经济性状的多元回归方程。结果表明 ,绵 5优 5 2 7的千粒重变异不大 ,有效穗是产量构成的最重要因素 ,保持一定的实粒数是高产的前提。

The relations between yield and yield components of “mian5you527”, a new hybrid rice combination with fine quality in Sichuan, were analyzed through correlation and path coefficient analysis, and got the multiple regression equation of the main economic traits. The result showed that 1000-grain weight of the variety varied little, the reasonable grain number per panicle was a prerequisite for high yield, and effective panicles per uint area was the most important of yield.
