Quantitative trait loci analysis of chlorophyll content for flag leaf in rice

Chlorophyll contents are one of important physiological traits, which affect photosynthesis in plants. There were significant differences in chlorophyll contents between Zhaiyeqing 8(ZYQ 8), an indica variety and Jingxi 17(JX 17), a japonica variety (Table 1). In 117 DH lines of the cross of ZYQ 8/ JX 17, these parameters distributed conTwo neutral alleles of improving male gamete abortion in indica-japonica hybrid rice LU Chuangen and ZOU Jiangshi, Jiangsu Acad of Agri Sci, Nanjing 210014, China
