近期我国的花生育种目标可归纳为抗病优质、高产和早熟,而其中高产是最基本的育种目标。产量是一个综合性状,并与其它性状之间存在着十分复杂的遗传关系。植株的光合作用是产量的物质来源。因此,研究花生叶部性状与产量性状的遗传关系,对于合理调节群体光合结构,培育高产品种具有重要意义。本文拟作花生主要叶部性状与产量性状的通径分析,阐述各种叶部性状对产量性状的相对重要性,为育种中的选择提供参考。
Recently, the objectives of peanut breeding in China can be summed up as high quality, high yield and early maturity, of which high yield is the most basic breeding goal. Yield is a comprehensive trait and has a very complex genetic relationship with other traits. Plant photosynthesis is the material source of yield. Therefore, studying the genetic relationship between leaf traits and yield traits in peanut is of great significance for the rational regulation of population photosynthetic structure and breeding of high-yielding varieties. In this paper, the path analysis of major leaf traits and yield traits in peanut was conducted, and the relative importance of various leaf traits to yield traits was expounded, which provided references for breeding selection.
