Abstract:

For the mid-1980s, Sichuan, Chongqing and breeding wheat area and production of varieties of the direction and approval contradiction between the need to practice. From the development of production, market economy and the people need, analyzes the wheat was more validation and promote the use of fewer phenomenon, summed up the red species of small grain spikelet promote slow, farmers do not want to grow, big ear white species of large grain promotion of speed reasons. Proposed a "commodity-based high-quality disease-resistant breeding big ear big grain harvest sprouting resistance of new varieties of white wheat" breeding a new direction. After 20 years of efforts, and encouraged the ‘Mianyang25’, ‘Mianyang26’, ‘Mianyang27’, ‘Mianyang28’, ‘Mianyang31’, ‘Xikemai1’, ‘Xikemai6’ number of other white wheat varieties, these varieties of wheat in Sichuan Province has become the sixth largest replacement headed varieties. Of Sichuan Province and China's wheat breeding, wheat production and food security in the country made a great contribution. Promote the cultivation of varieties of the above, that white wheat varieties in yield, quality, disease resistance and other aspects as much as red wheat, and in the value of commodities, promotion speed is superior to red species. As a result, I believe, is easy to break through the traditional red wheat breeding validation constraints, the market economy, people's needs, social development closely, breeding high-yielding commodity-based, high-quality, disease resistance, large panicle large grain wheat harvest sprouting resistance varieties of wheat breeding is Xinan Mai District, a new direction.
