Precocious, Disease Resistant, Quality Chinese Cabbage - Jin Qiu Wang

"Jinqiuwang" Chinese cabbage is the early-maturity, disease-resistant, high-quality, and resistant-storage straight-type variety cultivated by the TuMV resistance cross breeding technique of Shandong Cabbage Center Weishan Office. Its wide adaptability, strong resistance, suitable for early autumn and winter storage cultivation in most areas of China. After 2001-2003, demonstrations of variety and trials across the country showed that its high-quality, storage-resistant, disease-resistant and precocious performances have been outstanding. Currently, they have been established in Lu, Yu, Shan, Gan, Ning, Yun, Gui and Chuan. Black, Kyrgyzstan, Liaoning, Inner Mongolia and more than 20 provinces have been widely promoted. I. Breeding After the "Jinqiuwang" Chinese cabbage is bred by two self-incompatible lines, 99-8 and 99-16, as parents. 99-8 After crossbreeding with Tianjin Bunting leaves and B75, it has been selected from successive generations of self-crossing systems. The affinity index is 0.28-0.46, and the growth period is 55 days. The leaf color is dark green and the spine is buckled. Strong disease resistance. 99-16 is a self-incompatible line created by self-intersection of several generations of Jincao No. 3, with an affinity index of 0.42-0.65. The growth period is 60 days. The leaves are green, and the piles in the leaves are comfortable. Good disease resistance. In 2000, the test was successful. Second, the characteristics of "Jinqiu" growth period 60-65 days, outer leaves dark green, light green ribs, degree of development 48-52 cm, plant height 35-38 cm, straight-shaped, ball screwed hold, ball top Comfortable, ball height 32 cm, diameter 14 cm. Single ball mass 2-3 kg, net meal rate 62%, soft leaf rate 58.6%. This species is highly resistant to viral disease, and it is also resistant to soft rot and downy mildew. After a 3-year regional survey, the disease index of viral disease, downy mildew, and soft rot disease was 0.6%, 28%, and 12.1%, respectively. The quality of the variety is sweet and delicate, and the cooked food is easy to be rotten. The quality is excellent, and it is resistant to storage and transportation. Third, the cultivation of technical points The compact plant type is particularly suitable for close planting, planting 3300-3500 per acre is appropriate. To apply basic fertilizers, mainly high-quality organic fertilizers, three-water seedlings, and five-water fixed trees, the topdressing nitrogen and nitrogen fertilizers should be applied in time during the rosette stage and the ball-bearing period. The growth period of this variety is short. Promote the prevention of pests and diseases in a timely manner.
