Abstract 农大3338是通过多年鉴定发现的一个优良的光温敏核雄性不 育小麦品系,运用SSR和ISSR两种分子标记对其光温敏核雄性不育基因进行了定位,检测到 了两个光温敏核雄性不育基因座位,并分别命名为 ptms1和ptms2,其中ptms 1的基因效应是ptms2 的2~3倍。 |

Abstract The photoperiod-temperature sensitive genic male s terile (PTSGMS) line in wheat is important for the utilization of heterosis.The wheat line,BAU3338,is an excellent PTSGMS material identified in the recent year s.In this study,its PTSGMS genes were mapped using molecular markers,SSR and ISS R.The result of molecular analysis showed that the two PTSGMS loci were identifi ed and designated as ptms1 and ptms2 ,respective ly.In addition,the genetic effect analysis indicated that the locus effect of ptms1 was 2~3 times larger than that of ptms2 . |
