我们在研究番茄自然变异不育株的遗传规律中,发现了具有苗期连锁标记性状的雄蕊退化新类型。现已育成了“农大土豆红”雄性不育两用系,并开始用于生产,为番茄杂种优势的利用,找到了一条低成本的简易杂交制种新途径。现将其有关性状及其遗传和杂交制种方法等简介如下:
In studying the genetic rules of naturally mutated lines of tomato, we found a new type of stamen degeneration with linkage markers in seedling stage. Has now developed a “agricultural potatoes red” male sterile dual-purpose lines, and began to be used for the production of tomato heterosis utilization, found a low-cost easy hybrid crossbreeding a new way. Now its related traits and genetic and hybrid seed production methods are as follows:
