Suiyu 5 by the Academy of Agricultural Sciences in Heilongjiang Academy of Agricultural Sciences Suihua bred in 1988, the combination of BC482 1_2 × 15 46 19. The species is a single early-maturing cross-species, emergence to mature 10 9d, the need for ≥ 10 ℃ active accumulated temperature 2 2 5 49 ℃ · d. From 1989 to 1993, different yield test showed the features of early maturity, high yield, disease resistance and so on. In the hectare seedling 5000000 density, the average yield of 7811 2kg hectare, than the standard varieties of jade jade 5 10% increase. It is suitable for the low humid zone in the eastern part of the third accumulated temperate zone in Heilongjiang Province and the hilly area in the western plain, and the semi-mountainous area in the eastern part of Jilin Province. Generally suitable for planting in early May, the variety like fertilizer, yield potential. Seed production can be planted in the same period as the parents, with 5,000 to 60,000 hectares of seedlings per hectare. The proportion of parents planting this 1: 4.
