The results of the regional test in Hunan Province included a plant height of 183.8 cm, a number of effective branching of 8.5, and 353 valid pods per plant, with 21.9 granules per kerf and a weight of 3.65 g. Field performance of Sclerotinia and the incidence of viral diseases is low. Production and Quality In 2002, the average regional test yield of rapeseed in Hunan Province was 136.39 kg, which was 4.52% higher than that of the control (Xianyou No.13, the same below). In 2003, the average yield of 667 square meters of rapeseed was 137.83 kg. An increase of 4.33% was achieved; in 2004, an average of 667 square meters of rapeseed production was 184.39 kg, an increase of 18.25% over the control. Quality test: The seed oil content was 39.89%, the erucic acid content was 0.98%, and the glucosinolate content was 41.24 μmol/g. Cultivation points Sow seedlings are planted around September 10, with a sowing rate of 0.5 kilograms to 0.6 kilograms per 667 square meters. Live cultivation should be sown in late September. The sowing amount per 667 square meters is 0.2 kg to 0.25 kg. Seedlings 6 leaves to 7 leaves, seedling age about 35 days when transplanting, before the end of October planted, 6000 to 8000 per 667 square meters planting. Live seedlings are 8000 to 10,000 plants per 667 square meters. For every 667 square meters of nitrogen, 11 kg to 15 kg of pure nitrogen, 7 kg of phosphorus pentoxide, 7 kg of potassium chloride, and 1 kg of borax. Apply enough base fertilizer to catch Miaofei as early as possible and reapply wax. After transplanting, weeding and weeding were conducted one or two times, and attention was paid to drought-resistant drainage. Pre-winter attention should be paid to locust-infested insects and cabbage worms, and attention should be paid to draining the drains after the spring to prevent Sclerotinia disease. Suitable areas The variety is suitable for planting in Hunan Province.
