The quantitative trait loci (QTLs) for 21 traits of agronomy importance on ten substituted chromosomal segments were identified using single segment substitution lines (SSSLs) in rice, which were developed by the use of Taichung 65 as a recipient and zhai-ye-qing and dee-geo-woo-gen as donors respectively. Total length of the substituted segments in the SSSLs was 230.00 cM, which was 12.62% of rice genome. T-test was used to detect QTLs in the condition that the difference in phenotypes between a SSSL and the recipient parent (Taichung 65) was significant at the 0.1% level (P< or = 0.001). A total of 57 QTLs for 17 traits had been detected on the ten substituted segments, which were on chromosomes 1, 3, 5, 7, 8, 10 and 12 respectively. The additive effect percentages of the QTLs ranged from 1.10% to 89.73%. Among of 57 QTLs, fifteen QTLs had the additive effect percentage over 10%, thirty QTLs varied from 3% to 10% and other twelve QTLs were below 3%.
利用以台中65为受体，分别以窄叶青和地谷为供体培育的单片段代换系（SSSLs），鉴定了水稻10个代换染色体片段上21个农艺重要性状的数量性状基因座（QTLs）。SSSLs中代换片段的总长度为230.00 cM，占水稻基因组的12.62%。采用t检验在单片段代换系与受体亲本（台中65）表型差异在0.1%水平显著（P≤0.001）的条件下检测QTLs。在10个代换片段上共检测到17个性状的57个QTLs，分别位于第1、3、5、7、8、10和12染色体上。QTLs的加性效应百分比范围为1.10%至89.73%。在57个QTLs中，15个QTLs的加性效应百分比超过10%，30个QTLs在3%至10%之间，其他12个QTLs低于3%。
