| 摘 要： | 对河南省11个玉米群体进行了产量等性状的综合分析,建议许白群和洛孟综、525群和二南24群作为相互群体继续改良,同时可作为综合种利用。结果表明群体出籽率、千粒重、穗粗等与产量间、GCA 间及其SCA 间均相关显著;群体穗长、穗粗,穗行数、出籽率、株高、穗位高等亲子相关显著。同时对与群体改良有关的问题进行了讨论,并扼要介绍了多点不完全双列杂交的配合力分析方法。

| Abstract: | 11 maize populations in Henan province were evaluated.Populationssuch as Xu Bai,Lue Meng Zhong,525 and 2 Nan24 were better.And we su-ggested that they should be improved continuely.The coefficients of correlationbetween threshing kernel rate,1000kernel weight,ear diameter and grain yieldwere significent.And so were the correlation between GCA,SCA of these tr-aits and grain yield.The coefficients of parent-offspring correlations of the traitssuch as ear length,ear diameter,kernel-row number,threshing kernel rate,plant height,ear height were Significent too. |
