Seventeen soybean crosses were made in 1978 to study the relationships between F1 hybrid performance and effectiveness of selection for seed yield in F4 and F5 generation lines. The seed yield level of F1. hybrid had no association with that of F4 and F5 generation lines. The high-yield crosses involved less parent difference in mature period had lower heterosis in the range of 117.7-134.9% and the heterosis indices of most of these crosses were around 120%. The high-yield crosses involved greater...

Seventeen soybean crosses were made in 1978 to study the relationships between F1 hybrid performance and effectiveness of selection for seed yield in F4 and F5 generation lines. The seed yield level of F1. hybrid had no association with that of F4 and F5 generation lines. The high-yield crosses involved less parent difference in mature period had lower heterosis in the range of 117.7-134.9% and the heterosis indices of most of these crosses were around 120%. The high-yield crosses involved greater parent difference in mature period had slightly high average heterosis, but the heterosis indices of most of these crosses also were around 120%. The seed yield heterosis of the low-yield crosses were greater than 140% or lower than 100%. The low-yield crosses had high or lowest vegetative growth heterosis, while high-yield crosses had intermediate vegetative growth heterosis. The leaf area heterosis of high yield crosses, generally were lower, ranging from 115% to 130%, but that of low-yield crosses were greater than 150%. The relationship between F1 dry leaf weight heterosis and effectiveness of selection in progenies was similer to that between F1 leaf area heterosis and effectiveness of selection in progenies. The most of low-yield crosses had highest or lowest special leaf weight heterosis, while the special leaf weight heterosis of high-yield crosses were 80-100%. The relationship between the heterosis of seed yield and that of vegetative growth was relative balance. In high-yield crosses, ratio of yield heterosis to vegetative growth heterosis was around 1.0 ranging from 0.85 to 1.17.

以1978年配制的17个组合为材料研究了大豆F_1杂种表现与选择效果的关系。 F_1代绝对产量水平与后代选择效果无规律性变化。两亲生育期差异较小的高产组合,其F_1代优势不很高,绝大部份组合的产量优势都小于140%,其中多数为120%左右。两亲差异较大的优良组合,有向优势变大方向分布的趋势。F_1优势大于140%的组合基本上无优良组合,而小于100%的组合则绝大多数为劣组合。F_1营养体高优势及最低优势组合的后代绝大部份表现不良。两亲生育期差异较小的组合中,优良者一般有中等程度的营养体优势。叶面积优势变幅为115—130%,超过150%的不是好组合。时干重优势与选择效果的关系类似于叶面积。F_1叶质重优势特高或低下的组合,后代绝大多数表现不良,优良组合的叶质重优势为80—100%。籽粒产量优势与营养体优势指数之间有一个平衡关系,优势组合中两者比值为1.0,变幅为0.85—1.17,过大过小后代选择效果均不良。

Three hundred plants selected from advanced generation line Nannong 82-4 were grown in a 2-replicate, randomized block layout in 1985~1987 crop season, and 500 plants from other line Nannong 2101 in 1987~1989 as well, to study the genetic variations, and genetic gains of four yield components. In addition, a comparison of actual efficiency of three complex selection methods was made. Pure-line selection still showed great potentialities when it was used to improve single character with deficiencies. But, in multi-trait selection the genetic variations, genetic gains and selection methods should be studied so as to raise the foresight and efficiency in pure-line selection.

在2个小麦高世代品系中进行单株选择、分系比较,分析4个产量性状的遗传变异程度和遗传进度,比较了3种综合选择法在小麦纯系育种中的选择效率。结果说明,针对原始群体的主要缺点,着重对个别性状的选择,纯系育种法还有很大潜力。但对综合性状的选择,有必要研究群体中各个性状的遗传变异度、遗传进度及综合选择方法,这便于有预见地进行选择,从而提高纯系育种的效率。
