| 摘 要： | 以四倍体皱缩叶类病毒病变突变体为母本,以不同的2x正常叶系为父本进行杂交,能够获得少量三倍体种子.三倍体自交,其后代会出现非整倍体、二倍体、三倍体、四倍体的倍性分离,以及正常叶与皱缩叶基因型的分离,其分离比例未呈现明显规律性.再以2x系为亲本,对分离群体中二倍体和四倍体皱缩叶株进行杂交选择,可以在不同世代选育获得二倍体和四倍体皱缩叶及正常叶型新种质,现已获得了熟性超亲和双亲未表现的白色果实等5个二倍体选系.以同一2x系为轮回亲本经多代回交选择,还可以获得具有二倍体轮回亲本农艺性状的二倍体和四倍体皱缩叶近等基因系.

| Abstract: | Lesion mimic mutant of tetraploid wrinkle leaves was used as female parent,and 2x lines with regular leaves as male parent,crossed them,a little triploid seeds were gained.When triploid makes selfing,in their progenies:aneuploid,diploid,triploid and tetraploid,ploidy segregation was found,so did the genetic segregation of regular leaves and wrinkled ones.It hadn't an obvious regularity in separation rate.The 2x line is used as parent,the plants with wrinkled leaves of diploid and tetraploid in segregational... |
