【摘要】 从转入 bar 基因的籼稻半矮秆材料9311HR 的 BC₃F₂中发现了1株高秆突变体 9311HR-T,其株高和秆长分别比野生型9311HR 增加60.8%和71.5%,其高秆性状受1对显性基因控制。以9311HR-T 与02428杂交产生的 F₂群体为材料,利用微卫星标记将9311HR-T 高秆基因定位在水稻第1染色体长臂上的 SSR 标记 RM472和 RM1387之间,距 RM472和 RM1387的遗传距离分别为8.6 cM 和12.3 cM,该基因暂命名为 DTl。更多还原

【Abstract】 A long-culm mutant,9311HR-T,which was found in the BC3F2 of transgenic rice 9311HR resistant to herbicide basra bred by transferring the bar gene into the indica line 9311.Compared with 9311HR,plant height and culm length of 9311HR-T was increased by 60.8% and 71.5%,respectively.The long-calm trait of 9311HR-T was controlled by a dominant gene,which was designated tentatively as DT1.By molecular marker analysis of a F₂ population of 9311HR- T and 02428,the long-culm mutant gene DT1 was located on the long arm of rice chromosome 1,between microsatellite markers RM472 and RM1387,with genetic distance of 8.6 cM and 12.3 cM,respectively.更多还原
