用S Wright多元分析法及其公式,对提高F1代玉米杂交种产量有关的主要性状进行相关和通径分析,结果表明穗粗性状对产量的正向效应最大,其次是穗长,再次为千粒重。
S Wright multivariate analysis and its formula, to improve the yield F1 hybrid generation of major traits related to the correlation analysis and path analysis, the results show that the panicle traits on the yield the largest positive effect, followed by the spike length, again for the 1000-grain weight .
