摘要: 试验结果表明混合选择与全姊妹轮回选择对于改良玉米群体的经济性状及植株性状都是有效的,而且效应是累积的。选择对于产量性状的效应,以选择世代来比较,轮回选择大于混合选择;以时间来计算效益,二者差不多。两种方法获得改良效果的原因都在于优良性状个体频率的增加,而优良基因型频率增加的基础,在于优良基因的重组,所以玉米

Abstract: The present study has reached to the conclusion that full-sib recur-rent selection and mass selection are equally effective for increasingmaize grain yield and plant traits in a basic population developed byourself.In comparing the magnitude of gains in grain yield within thesame period of selection
