【摘要】 本文介绍了甜菜单粒型雄性不育系内糖工农m101的选育过程。先以单粒雄性不育株7418为母本以多粒型自文系自₁₂为父本进行杂交,从杂交母本株上收获的F₁作父本与自₁₂回交,再以回交后代为父本与单粒雄性不育株进行杂交,在10年内选育出了单粒雄性不育系。并对m101的选育实践及m101×8-8₇₂₂组合的杂种优势进行了讨论。更多还原

【Abstract】 The breeding process of sugarbeet monogerm male sterile line NeiTang GongNong M101 was described.In the initial stage of the process the monogerm male sterile plant No.7418 was crossed as maternal with the inbreed line Zi-12.Subsequently the backcross was made with the F1 of No.7418 ×Zi-12 and Zi-12.Following that the progeny of the backeross was crossed as paternal with the monogerm male sterile plant.The M101 was finally selected as the monogerm male sterile line by the end of the course of nine years （1980-1988）.The practice for breeding the line was discussed as well as the heterosis of the combina- tion of M101×8-8₇₂₂.更多还原
