摘　　要：:水稻多酚氧化酶活性的遗传最少由 5对微效基因控制 ;遗传效应的组成中 ,以加性效应为主要 ,但也表现出较大的显性效应 ,不存在显著的上位性 ;水稻对白叶枯病的抗性与多酚氧化酶活性呈显著遗传相关 ;受白叶枯病侵染后 ,最少有另外The polyphenol oxidase activity in rice is controlled by five pairs of minigenes at least. Additive effect is mostly factor within genetic effect, there are also fairly dominant effect, and not exiting epistasis effect. There are strongly genetic correlation between the polyphenol oxidase activity in rice and resistance to bacterial blight ( Xanthomonas campestris PV. Oryzas ). There was four other pairs of actived minigenes at least infected by bacterial blight.
