在作物育种工作中,株高、生育期以及产量性状,是在确定育种目标中所考虑的主要内容,这些性状之间的关系已被广大育种者所基本掌握。但是,随着育种工作的发展,对一些农艺性状的遗传规律仍需进一步探讨。玉米的这些性状在杂交后代的表现与其他作物不尽相同。本文即通过试验、观察和分析,对株高、生育期以及产量性状在杂交种后代的遗传表现规律作了进一步探索,现综述如下:
In crop breeding, plant height, growth period and yield traits are the main contents to be considered in determining breeding objectives. The relationship among these traits has been basically mastered by the majority of breeders. However, with the development of breeding, the genetic laws of some agronomic traits still need to be further explored. These traits of maize differ from those of other crops in hybrids. This article through the experiment, observation and analysis of the plant height, growth period and yield traits in the genetic characteristics of hybrid progeny made further exploration, are summarized as follows:
