【摘要】 1997年在山西省农科院作物遗传研究所棉花试验田发现1株天然变异双铃短果枝鸡脚叶光籽棉,采用系选法,从中又发现不同株型、不同叶型、不同铃型、不同籽型的基因突变型分离株。经过试验观察,其遗传稳定性,从而选育出双铃光籽一体的2001—<67优质棉新品系,成为我国独特的珍贵的种质资源。经遗传分析,利用双铃光籽的指示性状,提供杂种优势利用,简化制种工序,从而开创棉花增产的新途径。更多还原

【Abstract】 Neked-seed cotton with double-ball and short fruit blanch was identified in 1997.Through selection many plants with different plant types,leat types,ball types and seed types were identified.Thoroug test and survey,selected neked-seed and double-ball 2001—<6₇ line.This is a valuable species resource.Through genetic analysis,utilization index shape of double-ball and naked-seed may start new way to increase production of cotton.更多还原
