| 1 | GL9 from Oryza glumaepatula controls grain size and chalkiness in rice显示文摘Grain size is a key factor influencing grain yield and appearance quality in rice.We identified twelve quantitative trait loci(QTL)for grain length(GL),nine for grain width(GW),and nine for 1000-kernel weight(TKW)using GLU-SSSLs,which are single-segment substitution lines with Oryza glumaepatula as donor parent and Huajingxian 74(HJX74)as recipient parent.Among the QTL,qGL1-2,qGL1-4,qGL9-2,qGW2-2,qGW9-1 and qTKW9-2 contributed to high grain yield.GL9 was identified as a candidate gene for qGL9-2 by map-based cloning and sequencing,and is a novel allele of GS9.The kernel of NIL-gl9was slenderer and longer than that of HJX74,and the TKW and grain yield per plant of NIL-gl9 were higher than those of HJX74.The proportion of grain chalkiness of NIL-gl9 was much lower than that of HJX74.Thus,gl9 increased grain yield and appearance quality simultaneously.Three pyramid lines,NIL-gs3/gl9,NIL-GW7/gl9 and NIL-gw8/gl9,were developed and the kernel of each was longer than that of the corresponding recipient parent lines.The gl9 allele may be beneficial for breeding rice varieties with high grain yield and good appearance quality. | Shaojun Lin Zupei Liu Kui Zhang Weifeng Yang Penglin Zhan Quanya Tan Yajun Gou Shuaipeng Ma Xin Luan Chubing Huang Zhili Xiao Yuanyuan Liu Bihuang Zhu Ruiqing Liang Wenqi Zhou Haitao Zhu Suhong Bu Guifu Liu Guiquan Zhang Shaokui Wang | 2023 | The Crop Journal2023，11，1： | 1 |
