- Abstract:
- Jiyu 612 is a high-yield and quality ‘double-high’ soybean hybrid which was selected by the ‘three-line’ method. The maternal sterile line is JLCMS57A, and the parental restorer line is JLR9. The main characteristics of Jiyu 612 are high and stable yield, good quality and strong disease resistance. In the two-year regional trials, the average yield increased by 16.0% compared with the control variety, and the production trial increased by 4.4% compared with the control variety. Jiyu 612 is resistance to soybean mosaic virus disease and high resistance to soybean gray spot disease by artificial inoculation identification. The grain fat content is 20.92% and the protein content is 42.07%. Jiyu 612 seed production must be with drought, less rain, irrigation conditions. And the plant areas must be with many natural insect populations. Parents must be planted at different times with planting ratio of 1∶2 or 1∶3 and density of 150 000 plants?ha-1. Honey bees also can be used for pollination, and the mixed and inferior plants must be strictly removed during entire growth period to ensure the purity of the seeds.
