摘    要:利用矮秆基因RhtB1-b、RhtD1-b和Rht8特异分子标记对郑麦583和2015-2016年度参加河南省区域试验、河南省品种比较试验、国家黄淮南片区域试验及国家黄淮麦区品种比较试验的共630份小麦材料的基因型进行检测。结果表明,供试材料中检测到549份材料含有RhtB1-b基因;592份材料含有RhtD1-b基因;513份材料含有Rht8基因;422份材料同时含有3个矮秆基因,169份材料仅含有2个矮秆基因,说明3个主要的矮秆基因在河南小麦育种过程中被聚合使用。此外,分析发现,矮秆基因Rht8与株高和每公顷穗数,以及千粒重具有显著相关性。郑麦583等小麦品种聚合了这3个矮秆基因,具有优良的丰产性,通过选择和利用矮秆基因对于培育具有丰产性优点的小麦品种具有一定价值。

关 键 词:小麦  株高  矮秆基因  农艺性状

Abstract:In this study, Zhengmai 583 and 630 materials derived from variety comparison test and regional trials of Yellow-Huai wheat area and Henan Province at 2015-2016 were screened by specific molecular marker of wheat dwarf genes RhtB1-b, RhtD1-b and Rht8. The results showed that 549 wheat materials carried RhtB1-b gene; 592 wheat materials carried RhtD1-b gene; 513 wheat materials carried Rht8 gene; 422 materials carried all 3 dwarfing genes, and additional 169 lines carried 2 dwarfing genes which indicated that the 3 dwarf genes had been fixed in Henan wheat breeding progress. Moreover, Rht8 showed significantly correlation with reducing plant height, spike number per hectare and increasing 1000-kernel weight. Zhengmai 583 carried 3 dwarf genes, showed excellent fertility. The selection and utilization of dwarf genes are of certain value for the cultivation of wheat varieties with high yield.
Keywords:Wheat  Plant height  Dwarfing gene  Agronomic traits
