Application of Anther Culture Technology in Rice Breeding

Edible Gardening 0 views
Using disease-resistant plants from the first backcross generation for anther culture can transfer disease-resistance genes into japonica rice in a short time, accelerating the process of disease-resistant breeding in japonica rice. Zhejiang Agricultural University began making crosses in 1975. An anther culture was carried out in 1976, and by 1977 stable varieties resistant to rice blast and bacterial leaf blight, such as Dan 209, had been developed. The whole process took only 3 years, and resistance genes for two diseases were transferred at the same time; its breeding speed and efficiency greatly exceeded the conventional research methods of Japanese scholars. This study also explored the approach of applying the anther culture method in seed production to produce foundation seed. Tests showed that pure lines from anther culture had a certain effect of purification and rejuvenation compared with foundation seed produced by the "three-plot method." Anther-cultured disease-resistant varieties have now been used as resistance sources for late japonica rice.
