Breed Source: The breed was hybridized by the Rice Research Institute of Heilongjiang Academy of Agricultural Sciences. In 1990, it was examined and approved by the Provincial Crop Variety Approval Committee to determine the promotion. Yield performance: From 1986 to 1987, the province participated in the regional test of 3 accumulated temperate zone. The average yield at 13 o’clock was 5548.2 kg / ha. The yield was 5.0% higher than that of the control variety Hejiang 19 and from 1988 to 1989, The average yield at the point was 6840.5 kg / ha, an increase of 9.1% on average compared with the control variety Hejiang No. 19. Characteristics: The variety of breeding days, 110-115 days under direct seeding conditions, transplanting cultivation conditions than the control variety Hejiang 19 night 1-2 days, the activity accumulated temperature 2230 ~ 2300 ℃, height 81-85 cm, each ear The grain number is about 70, the false rate is low, the grain weight is about 27 grams, the rice quality is better, the brown rice rate is 83.0%, the chalkiness size is 5.1, the protein content is 8.85% and the amylose content is 18.9%. Low temperature at budding stage, strong tillering ability, green leaf color, strong stalk resistance, Ying and Ying sharp stalk yellow, rare short, more resistant to blast. Cultivation points: The varieties suitable for moderate fertility cultivation, one
