| 摘 要： | 本文通过II优718品种两年国家区试资料,分析了6个性状与产量的相关、回归与通径关系,建立了回归方程:Y=-7.6423 0.0181X1 0.0085X2 0.0144X3-0.0375X4 0.0713X5 0.1954X6;明确了各性状对产量的贡献大小顺序:每穗实粒数>每亩有效穗数>千粒重>生育期>株高>每穗总粒数。

| Abstract: | This paper analyzed the correlation,regression and path relationship of 6 traits with the yield trait in II You 718 using materials of two years' national regional variety trials.One regression equation was established as Y=-7.6423 0.0181X_1 0.0085X_2 0.0144X_3-0.0375X_4 0.0713X_5 0.1954X_6.The contributory degree of each trait to the yield in descending order is as follows: the fertile spikelets per panicle,effective panicles in unit area,1000-grain weight,growth period,plant height,total kernels per panicle. |
