China's current development potential for the production of sunflower oil
Sunflower originated in North America. According to the test, it was introduced in China during the period, but mostly it was ornamental with flowers or nuts. After the release, Chinese breeders introduced oil sunflowers from the former Soviet Union and began developing large-scale oil sunflowers. The varieties that were promoted at that time were conventional varieties, with a long period of growth, low oil content, unstable yield, only within a certain range. Promoted inside.
With the promotion of microwave drying machinery and equipment technology, the production of sunflower oil is gradually increasing. The oil yield of the sunflower oil press is much higher than the traditional press method.
In the 1960s, the French discovered the cytoplasmic male sterile sunflower line, and gradually matched the infertile maintenance line and the sterile restoration line to carry out the production and promotion of the three-line sunflower hybrids. In the 1970s, China introduced France's male-sterile sunflower source, and gradually began to apply the hybrid of three sunflower oil lines in agricultural production.
