摘要
双抗明占是携带有抗稻瘿蚊基因Gm6的抗蚊青占与多系1号杂交的后代,经多年多点自然诱发鉴定筛选出抗稻瘟病和稻瘿蚊的恢复系,并经分子标记检测具有Gm6基因。双抗明占及其配制的杂交稻经抗稻瘿蚊试验,结果表明:抗蚊青占与双抗明占及其配制的杂交稻组合之间差异不显著,而与没有抗源的恢复系明恢100及其配制的杂交稻组合金优明100之间存在着极显著的差异;双抗明占是三系不育系的强恢复系,用双抗明占配制的杂交稻组合特优明占表现高产、中抗稻瘟病。
Shuangkangmingzhan has been proven to contain gene Gm6 through detection by molecular marker. It is the progeny of Kangwenqingzhan, which carries Gm6 that repels rice gall midge, crossed with Duoxi 1. It is the restored line against rice blast and rice gall midge resulting from years of natural and spontaneous selection process in multiple locations. The resistance test on Shuangkangmingzhan and its hybrid combinations with rice gall midge showed no significant difference between them. However, a significant difference existed between the restored line Minghui 100 and its hybrid combination Jinyouming100, which had no resistance resource. Shuangkangmingzhan is the restored line with restoring ability to the indica rice CMS line. And Teyoumingzhan is hybridized between Shuangkangmingzhan and Longtepu A. When the two were hybridized the resultant rice strain showed high grain yield and moderate resistance to rice blast.
