摘要: 巨穗小麦新种质材料是一具有茎杆粗壮、叶片短宽直立、大穗、大粒、高结实率等特点的种质资源.本研究应用单体分析和双端体分析方法对241材料进行了遗传学研究.结果表明, 小麦新种质材料241的1A,A,5A和4B染色体上具有控制株高的隐性基因,6B染色体上具有控制株高的显性基因,其中A,5A和6B染色体上的基因表现为强效,1A和4B染色体上的基因表现为弱效. 通过双端体分析进一步将控制株高的基因定位到1AS,AS,5AL和4BL上.

Abstract: The genes which controled the height of the giant spike wheat germplasm 241 were located on chromosome and chromosome arms with Chinese spring monosomic series and ditelosomic series as the testing lines.The results showed that the height of 241 is controlled by genes on the chromosomes 1AS,3AS,5AL,4BL and 6B respectively,three major genes on 3AS,5AL and 6B,and two minor gene on 1AS and 4BL.The result of monosomic analysis indicated that the four genes are recessive (1A,3A,5A and 4B),and the gene on chromosome 6B is dominant.

Key words: Giant spike wheat germplasm, Height, Monosomic analysis, Ditelosomic analysis, Gene location
