DISCOVERY AND DETERMINATION OF A DOMINANT MALE-STERILE GENE AND

<正> This paper deals with the determination of one male-sterile plant found in Chinese wheatcultivar (T. aestuvum L.). It is the first time in the world that a spontaneous mutant is dis-eovered in wheat. This dominant male-sterile gene is assigned as Ta 1. This determinationfirmly confirms the existence of the genic male-sterility and provides once again the scien-tific evidence to solve the argument of this problem. On the other hand, a breeding programof using this gene, especially in recurrent selection, is herewith proposed.
