| 摘 要： | 以川香29B和中国香稻构建的重组自交系群体为材料,通过建立144个SSR标记连锁遗传图谱,采用复合区间作图法对水稻外观品质和蒸煮食味品质的相关性状进行了数量性状基因定位。共检测到了45个与水稻粒长、粒宽、长宽比、垩白率、直链淀粉含量、糊化温度相关的QTL,分布在水稻的第1、2、3、4、6、7、9、10、12染色体上,其中有9个QTL的效应被重复检测到。

| Abstract: | A linkage map consisted of 144 SSR(simple sequence repeat) markers was constructed based on a recombinant inbred line(RIL) population of rice from the cross between Chuanxiang 29B and Zhongguoxiangdao.Quantitative trait loci(QTLs) related with rice qualities of appearance,cooking and eating were analyzed.A total of 45 QTLs for grain length,grain width,length-width rate,chalkiness rate,amylase content and alkali spread value were identified and mapped onto the rice chromosome 1,2,3,4,6,7,9,10 and 12.Nine QTLs can be repetively detected in two years.These QTLs were useful for improving the quality of Chuanxiang 29B through molecular marker-assisted selection. |
