Only a good variety can make a big enterprise.

The corn seed industry has developed by leaps and bounds in recent decades, which is reflected in the continuous expansion of corn planting area. The planting area of less than 200 million mu in the early days of liberation has hovered at the level of 200 million mu for 30 years, exceeded 300 million mu in the 1990s, maintained this level for 15 years, exceeded 400 million mu in 2005, and began to exceed 500 million mu in 2011. it is expected to reach 550 million mu this year.

The development of planting area provides a good condition for maize breeding, which is based on two points: one is the increase of population and the improvement of people's living standards; the other is the adjustment of industrial structure. Corn belongs to crops with high light efficiency and good production capacity, and the comparative benefit is relatively good. All these have created good conditions for the development of maize seed industry. At the same time, the development of corn is also faced with certain restrictions. according to the current distribution of crops in China, the threshold of corn seed planting area in China will not exceed 600 million mu. The improvement of maize yield per mu can only be completed by the seed industry, which poses a challenge to how to adapt to mechanized production and how to increase comprehensive stress resistance.

A good enterprise depends on variety, and without variety, it is impossible to make a big enterprise. Without hybrid rice, there would be no Yuan Longping. Without Canyou 63, there would be no Xie Huaan. Liangyu Company made a net profit of more than 80 million yuan last year. What does it rely on? it is a series of varieties of Liangyu cultivated by Song Xieliang. Now is the best period for the development of enterprises, there are a lot of good policies and project support, seed enterprises as a whole is much bigger and stronger than the initial stage of industrialization, but the overall is still small and messy. At present, the backlog of the seed market is expanding, and the burden is very heavy. under such circumstances, enterprises should be solid and refined, and the times should make heroes. Enterprises should sort out their ideas for future development according to their own scale, and large enterprises should continue to engage in breeding. research and development of competitive new varieties, medium-sized enterprises can join hands with scientific research institutes to tackle key problems, and small enterprises can make profits by buying good varieties. But in the final analysis, it still depends on the variety. It is hoped that this conference can reach a consensus on breeding cooperation and make use of their respective advantages to jointly select and breed really good varieties.
