| 摘 要： | 通过t测验比较了单片段代换系与受体亲本华粳籼74之间的表型差异，对以6个水稻品种为供体的52个单片段代换系代换片段上株高及其构成因素的QTL进行了鉴定。以P≤0.001为阈值，在14个代换片段上共鉴定出24个QTL，包括10个株高QTL、2个穗长QTL、4个倒1节间长QTL、5个倒2节间长QTL、3个倒3节间长QTL，这些QTL分布于水稻的9条染色体上。QTL加性效应值为-4.08～3.98 cm，加性效应百分率为-19.35%～10.43%。

| Abstract: | QTL for plant height and its components on the substituted segments of 52 single segment substitution lines(SSSLs) in rice were identified between SSSLs and the recipient parent Huajingxian 74 by t-test.On 14 substituted segments,24 QTL were detected,10 for plant height,2 for panicle length,4 for length of the first internode from the top, 5 for the length of the second internode from the top and 3 for the length of the third internode from the top,respectively.All these QTLs were distributed on 9 rice chromosomes except chromosomes 5,9 and 11.The additive effect of QTL ranged from 4.08 to 3.98 cm.And the additive effect percentages of the QTL varied from 19.35% to 10.43%. |
