Qin oil on the 2nd of Shaanxi Provincial Land Reclamation Science and Technology Education Center researcher Li Dianrong and other comrades after years of unremitting efforts to cultivate the success of the world’s first hybrid rape combination. The original test code hybrid 37, by the end of 1985 by the Shaanxi Provincial Crop Variety Approval Committee approved, named Qin oil on the 2nd. 1987 QinYu 2 has been promoted to more than 60 million mu, all over China’s rapeseed areas more than 10 provinces, municipalities, of which the largest area in Shaanxi Guanzhong. During the course of undertaking seed production in the province, our county explored and concluded through several years of continuous improvement of seed production techniques. The output per mu increased from 25.7 kg in 1985 to 47.15 kg in 1986, a growth rate of 45.5%. In order to further improve the seed production, we must master hybrid theory
