摘 要 ：该新三体于1983年发现,1984年鉴定。新三体的超数染色体为带随体的染色体,命名为Trisomic E(简写为 Tri E),其四体应称为随体四体(Satellite tetrasomic)。非整倍体的原始真叶较小,生长势较弱,单株结荚数比二倍体少得多。控制茸毛色的基因(t)可以定位在新三体的超数染色体上。
Abstract:The new trisomic was found in 1983 and identified in 1984.The extra chromosome ofthe trisomic is one with a satellite.This new trisomic is designated as Trisomic E(Tri E).The tetrasomic should be called satellite tetrasomic.The primary leaves ofaneuploid were smaller and less vigorous.The pod number
