摘    要:本文以低粒重的多小穗品种"10阿"为被测材料,"中国春" 和"阿勃"两套单体系列为测验系,对粒重性状进行了基因定位研究.结果表明,被测材料"10阿"粒重低受5A、1B、2B、2D和7D等染色体上的隐性基因所控制。从其减小效应的程度来看,1B和2B染色体上的基因表现为强效。5A、6B、2D和7D染色体上的基因表现为弱效。

关 键 词:小麦  粒重  染色体  单体分析  基因定位

Abstract:Localization of genes for the 1000- grain weight of a multispikelet line of commonwheat (Triticum aestivum L.) with lower grain weight, "10--A", was carried out byusing the monosomic series of two varieties, "Chinese Spring" and "Abbondanza".The lower grain weight of the tested line "10--A" was found to be controlled by sixrecessive genes, located on chromosomes 5A, 1B, 2B 6B, 2D and 7D, respectively.The decreasing effects of genes on chromosomes 1B and 2B were obviously larger thanthose on chromosomes 5A, 6B, 2D and 7D. In other words, there are two majorgertes on chromosomes 1B and 2B; and four minor genes on chromosomes 5A, 6B,2D and 2D and 7D, respectively.
Keywords:Wheat(Triticum aestivum L.)  Grain weight  Monosomic analysis  Gene localization
