Four soybean crosses were made in 1976 , and the progenies of each cross were used for selection by following 7 methods : pedigree,"picking-pod method", mass selection for early, medium, and late maturity, and mass selection under 2.06 and 1.28 selection intensities.Expression of lines selected by these 7 kinds of method wereanaly-zed in 4 items: coefficient of variability (c.v.%) of F4 generations; yield of F3-F5 lines; visual discrimination of lines in field; and calcu- lation of relative genetic advance on 6 agronomic characters.The results showed that the coefficient of variability of plant height in F4 generation showed only little difference (7.12-10.38%), except "picking-pod method" (13.08%). Yieid test of lines selected by the 7 methods was undertaken under randomized block design with 5 replications. F value of yield of lines mong the 7 methods were not significant (F<1). Relative genetic advance ( △G/x% ) of agronomic characters (plant height, number of nodes on mainstems, number of branches, weight per 100 seeds, number of pods per plant and length of growth period) was significantly higher on lines selected under2.06 seleeion intensity than under 1.28 selection intensity.Owing to that, there is no significant difference among the genetic parameters the 7 methods studied, therefore those methods which are low cost, less labor needed, and suitable to have generation advance in winter nursery, would be the appropriate methods for soybean breeding. Among the 7 methods studied, "picking-pod method" belong to the appropriate kind.

The authors proposed compound character which is a combination ofmultiple metrical traits and give its heritability and its other geneticparameters. On this foundation, the canonical correlation between phenot-ypic random vector p_2 (m_2 dimesions) of many selection traits P_2=g_2+e_2and genotypic random vector g_1 (m_1 dimesions, m_1≤m_2) of a few aimtraits P_1=g_1+e_1are studied by using canonical analysis When environmental random vectoris independent of genotypic random vector, in solving the matrix equation (G_(12)P_2~(-1)G_(12) '-λ_2G_1) a=0where G_1、P_2、G_(12) is covariance matrix of g_1、P_2、g_1and P_2 respectively, characteristic roots γ_i~22 and its characteristic vectors a_i and (?)are obtained.Then canonical selection character p_i*=g_i*+e_i* i=1, ..., s

本文首先分析了一般测量性状的选择问题。根据作者提出的两性状间的相关遗传力和间接遗传系数,简化並统一了直接选择和间接选择的选择响应和遗传进展的表达式。接着提出了多个测量性状的复合性状的概念並给出了它的一些遗传参数。在此基础上,利用典范相关分析方法,着重研究了多个供选择的测量性状的表型变量与少数几个目标性状的基因型变量的相关关系,提出了典范选择性状与典范目标性状的概念,它们正是典范相关分析中典范相关系数较大的前几对典范变量。而第Ⅰ报中的典范性状只是这种典范变量对的特例。利用这少数几个典范选择性状对相应的典范目标性状进行间接选择,不仅具有利用典范性状进行选择的特点,而且因目标性状集中,更有利于对多个目标性状的综合选择。本文还讨论了典范选择性状与选择指数的关系。当只有一个目标性状时,它与一般选择指数等价;当有多个目标性状並分别有不同经济权重时,它对于典范目标性状的最大间接遗传系数大于综合选择指数对于复合基因型值的间接遗传系数,因而利用它可提高间接选择的可靠性。最后,本文讨论了典范选择性状在杂交亲本的选配及杂交后代的选择等方面的可能应用。
