| 摘 要： | 亚洲棉茎叶茸毛少而短，比克氏棉茎叶茸毛多而长，山西农业大学棉花育种组创育的〔（亚×比）〕Ｆ１双二倍体（２ｎ＝４ｘ＝５２，Ａ２Ａ２Ｇ１Ｇ１），茎、叶茸毛多而长，表明比克氏棉这一多毛抗虫性状被表达出来，本文用（亚×比）Ｆ１双二倍体与茸毛稀少的栽培四倍体海岛棉杂交，其多而密的茸毛性状能继续在杂种Ｆ１中得到表达。

| Abstract: | The stem and leaf of G.arboreum L.are covered with less and shorter pubscence,while those of G.bickii are covered with more and longer pubscence.By hybridization,allotetraploid (2n=4x=52,A 2A 2G 1G 1) inherited the character of more pubscence from G.bickii.In this study,by crossing the allotetraploid (A 2A 2G 1G 1) with (G. barbadense L. (AADD) 2;the more and longer pubscence contined to appear in the stem and leaf of the hybrid F 1. |
