糖甜菜是异花传粉植物,存在着自交不亲和机制。近年来,随着杂种优势的利用,许多学者研究了糖甜菜自交不亲和的遗传机制,提出了成功的研究方法,获得了自交系,并且把自交方法广泛应用于糖甜菜育种之中,取得了显著的成就。本文试图对这个值得注意的问题,做一简要概述。 Sugar beet is a cross-pollination plant, there is a self-incompatibility mechanism. In recent years, with the utilization of heterosis, many scholars have studied the genetic mechanism of sugar beet self-incompatibility, put forward a successful research methods, access to inbred lines, and self-cross method is widely used in sugar beet breeding China has made remarkable achievements. This article attempts to give a brief overview of this noteworthy issue.
