图3 代换片段在水稻染色体上的覆盖率 遗传距离(单位: cM)见左侧标尺; 染色体上黑色部分代表该区域可以被来自IAPAR9的代换片段所覆盖; 蓝色字体突出显示相关位点上已克隆的水稻粒型基因。

Fig. 3 Coverage of substitution fragments on rice chromosomes The genetic distance (cM) is shown as rulers on the left margin. Filled and open bars represent chromosomal segments homozygous for IAPAR9 and HJX74 alleles, respectively. The cloned genes are shown in blue font.
