通过对籼S×H3后代桴尖、叶缘、叶鞘颜色分离现象进行分析,明确了其基本遗传规律为:H3紫色稃尖这一性状受1对显性基因控制,籼S/H3后代中紫色叶缘、紫色叶鞘这两个性状均受2对显性基因控制,且2对基因可能完全一致或紧密连锁,而控制叶缘、叶鞘颜色的2对基因中的1对即可能就是控制稃尖颜色的基因,或为紧密连锁,不育基因与控制叶缘、叶鞘、桴尖颜色的基因均不连锁。 By analyzing the color separation of apical, leaf margin and leaf sheath of indica S × H3 progenies, the basic genetic rule was clarified as follows: the purple purple tip of H3 was controlled by one pair of dominant genes and the purple Leaf margin and purple leaf sheath are controlled by two pairs of dominant genes, and the two pairs of genes may be completely consistent or closely linked. One of the two pairs of genes that control the leaf margin and leaf sheath color may be the control tip Color of genes, or closely linked, sterile genes and leaf margin control, leaf sheath, tip color of the gene are not linked.
