本文报导了1979-1982年对水稻叶绿素的遗传研究。结果表明,叶绿素含量与a/b比值是稳定的遗传性状,具有杂种优势,属数量遗传性状,受微效多基因控制;叶绿素的遗传主要受核基因组所控制,叶绿体基因组虽有作用,但未表现出独立自主的遗传作用;叶绿素含量与a/b比值的广义遗传力分别为38.77-81.39％和46.42-77.27％,叶绿素含量与a/b比值和净光合速率(Pn)分别呈正相关与负相关。 This article reports the genetic study of rice chlorophyll from 1979 to 1982. The results showed that the ratio of chlorophyll to a / b was a stable genetic trait with heterosis. It was a quantitative genetic trait controlled by the microscopic polygene. Chlorophyll inheritance was mainly controlled by the nuclear genome. Although the chloroplast genome had a role, The results showed that the general heritability of chlorophyll content and a / b ratio were 38.77-81.39% and 46.42-77.27%, respectively. The chlorophyll content was positively and negatively correlated with the ratio of a / b and Pn .
