大豆多个数量性状的典型性相关分析

对大豆高油组合、高蛋白组合及常规组合材料的2个品质性状、9个农艺性状进行典型性相关分析,结果表明:品质中起主要作用的是脂肪含量,农艺性状中起主要作用的依次是主茎节数、单株粒重、全株荚数、底荚高度、全株粒数;生殖生长期和生育期对脂肪含量的影响最小。脂肪含量与单株粒重、全株荚数、底荚高度的选择有相互促进作用,可同时进行选择和改良;脂肪含量与主茎节数、全株粒数间存在一定的矛盾。

Canonical Correlation Analysis of Quantitatire Characters in Soybean

The canonical correlation analysis on two quality traits and nine agronomic traits was conducted with the materials of high oil combination,the high protein combination and the conventional combination.The results showed that the fat content played an important role in the quality traits,the order of the function in agronomic traits was number of nodes per stem,grain weight per plant、number of pods per plant,height of bottom pod,number of seeds per plant;repoductive stage and maturity period had less influence.grain weight per plant,number of pods per plant,height of bottom pod and the fat content could be promote mutually,they could be choiced and improved simultaneously;but number of nodes per stem,number of seeds per plant and the fat content had certain contradiction.
