摘  要：
本文报导了大豆不同结荚习性杂交F_2代生育的分离情况。无限×亚有限和相同结荚习性亲本之间杂交的F_2代生育期分离范围较窄;有限×无限的F_2代分离范围较广,相当于前者的二倍。F_2代分离类似极早熟亲本结荚习性的早熟材料多。产最因素间株高、节数、单株荚数和单株粒重呈极显著地正相关。无限和有限性的F_2代的百粒重与其它性状相关性不大,百粒重在亚有限F_2代中与单株荚数呈弱的负相关。同一组合分离出三种结荚习性的百粒重是相同的。

CORRELATION BETWEEN GROWTH PERIOD AND GROWTH HABIT AND YIELD IN F_2 GENERATION OF CROSSES BETWEEN SOYBEAN VARIETIES OF DIFFERENT GROWTH HABIT

摘  要：
Segregation of growth period in F2 of soybean crosses of different growth habit was studied. It is shown that the range of segregation in different crosses is different.The range of growth period segregation is small in F2 populations from crosses of indeterminate × semideterminate and crosses of the same growth habit. It is large in F2 populations from crosses of determinte × indeterminte, two times of the former. In F2 generation, lines with habit of the early parent are more.Significant correlation exists between the following yield factors: plant height, number of nodes, numder of pods per plant and seed weight per plant. No significant correlation exists between 100 seed weight and other characters in determinate and indeterminate and indeterminate types of the F2 generation. A weak negative correlation exists between 100 seed weight and number of pods per plant in semi-determinate type. 100 seed weight in the three F2 populations from same cross is also the same.
