提高水稻产量潜力是育种工作的主要目标之一。水稻产量是多基因控制的数量性状,易受环境条件影响,给产量性状的选择和产量潜力的提高带来了很大困难。近十几年来国内外应用相关和通径分析方法揭示了数量性状的遗传规律和动态,在国内外对籼稻的研究也日益增多,但对早粳研究并不多见。 本文通过对两年试验资料的相关及通径分析,研究了10个数量性状的遗传信息,从而为早
One of the major goals of breeding is to increase the yield potential of rice. Rice yield is a quantitative trait controlled by multiple genes and is easily affected by environmental conditions, which brings great difficulties to the selection of yield traits and the increase of yield potential. In the last ten years or so, application-related and path analysis methods at home and abroad have revealed the genetic laws and dynamics of quantitative traits. Research on indica rice has also been increasing at home and abroad, but research on early japonica rice is rare. In this paper, the correlation and path analysis of two years of experimental data were used to study the genetic information of 10 quantitative traits.
