从吉林引入的短叶柄材料公交７６２２—４—１—４ 在南京与２ 个长叶柄亲本南农９４—５２４、洪引１ 号杂交，表现一对基因分离结果，其与南京发现的短叶柄材料ＮＪ９０Ｌ—１ＳＰ杂交，Ｆ１ 和Ｆ２ 均表现为短叶柄，表明二者有相同的遗传基础，因ＮＪ９０Ｌ—１ＳＰ受两对隐性基因控制，故推论公交７６２２—４—１—４ 可能亦受两对隐性重叠基因控制。从南农８６—４×Ｄ７６—１６０９ 组合ＢＣ２Ｆ２ 群体初步结果表明，Ｄ７６—１６０９ 短叶柄性状与豆荚伏茸毛间存在连锁现象，重组率ｒ＝ ３．０１±１．２１％ 。源于ＮＪ９０Ｌ—１ＳＰ和公交７６２２—４—１—４ 的短叶柄叶枕不正常，农艺性状较差，尚难直接利用；源于Ｄ７６—１６０９ 的短叶柄与长叶柄后代相比表现晚熟、较易倒伏，但有可能获得高产、抗倒重组类型。
The short-stalked material bus 7622-4-1-4 introduced from Jilin was crossed with two long-stalked parents Nannong 94-524 and Hongyin 1 in Nanjing to show a pair of genetic segregation results. NJ90L-1SP, both F1 and F2 showed short petioles, indicating that both had the same genetic basis. Because NJ90L-1SP was controlled by two pairs of recessive genes, it could be deduced that public transport 7622-4-1-4 might also be affected by two pairs Implicit overlapping gene control. Preliminary results of the BC2F2 population from Nannong 86-4 × D76-1609 showed that there was a linkage between the short-stalked D76-1609 and the pods of the pods. The recombination rate was 3.01 ± 1.21%. Short stems from NJ90L-1SP and bus 7622-4-1-4 were abnormal, and their agronomic traits were poor and hard to be used directly. Short-stalked stems from D76-1609 were late-mature compared with long-petioles, Easy to lodging, but it is possible to obtain high yield, anti-heavy weight group type.
