摘要
２个短叶柄遗传材料ＮＪ９０Ｌ１ＳＰ及Ｄ７６１６０９与长叶柄品种（系）杂交的９个组合的后代分离结果表明：（１）新发现的突变体ＮＪ９０Ｌ１ＳＰ的短叶柄与不正常叶枕两性状之间为一因多效，受２对隐性重叠基因控制；（２）由美国引进的Ｄ７６１６０９的短叶柄性状受２对隐性重叠基因控制；（３）ＮＪ９０Ｌ１ＳＰ与Ｄ７６１６０９短叶柄性状的遗传控制不同，叶柄长度至少受两两重叠的４对基因控制。
he inheritance of short petiole was revealed from nine crosses:(1) The short petiole of D761609 was controlled by two duplicate recessive genes.(2) The short petiole of NJ90L1SP,a new mutant found in 1993,was completely linked with abnormal pulvinus.They were controlled by another two duplicate recessive genes.(3) There were at least four genes controlling the length of the petiole between D761609 and NJ90L1SP.
