How We Studied Hybrid Rice

Li Pi-hu

Abstract:
In 1964, we some young teachers and students in C-Y Agricultural School began to study "Three Lines" in rice (the male sterile line, the maintainer line and the pollen fertility recoverer line). In 19641965, we found six natural male sterile plants, but had not found an good maintainer line until 1970. Since then, under the steady leadership of our party and sincere concern by Chairman Hua Kuo-feng, the whole country has launched a vigorous mass movement of breeding "Three Lines" in rice and developed socialist cooperation. We have brought the spirit of self reliance and hard struggle into full play. On the basis of discovery of wild male sterile line in rice, we did numerous cross experiments with the rich resources of rice varieties in our country. In 1972, the maintainer line and the male sterile line were discovered and in 1973, the pollen fertility recoverer line was found. Thus we succeeded in the "Three Lines". During 19741976, by experimental plot, demonstrative planting and populization over wide areas, good result was finally obtained and the output of rice increased by 20%C30%. This is not only a new way to increase the output by a big margin, but also enrich the theory and practice in plant genetics and breedding.
