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。
This article reports the isolation of fertile F2 generations of different sowing habits in soybean. F_2 generations of infinitesimal × sub-limited and same pod habit parents had narrower range of segregation during F 2 generation; F 2 generations with limited × infinity had a wide range of separation, which was twice of the former. F_2 generation of very early maturing parents similar to the early pod habit of early material. The most productive factors between plant height, number of sections, pods per plant and grain weight per plant were extremely significantly positively correlated. The inflorescence and limited F 2 generations had little correlation with other traits, and the 100 kernel weight had a weak negative correlation with the pods per plant in the subfamily F_2 generation. The same combination of three pod habits isolated hundred weight is the same.
