A Single Recessive Photoperiod and Temperature Sensitive Genic Male Sterile Line Yahuang 396a in Cotton
1. The present situation and problems of breeding and seed production by using heterosis 1.1. The technique of artificial or chemical emasculation hybridization is simple, any two varieties can be parents of each other, anthesis emasculation and artificial pollination can be used, and chemical emasculation hybridization can also be used for seed production. The advantages are easy to make full use of existing variety resources, strong randomness of hybrid selection, free combination, and partial combination can use F2. Disadvantages are labor intensity, labor, high cost, F2 heterosis than F1 more decline. 1.2 cells
