Jinyou 207 rice

The breeding unit Hunan Hybrid Rice Research Center used Jin 23A and Xianhui 207, which was bred in 1995 and developed by Longping seed Industry. It has been examined and approved by Hunan, Guizhou, Guangxi and Hubei provinces.

The variety belongs to mid-mature indica late rice. The plant type is moderate, the plant height is about 100 cm, the growth potential is general, the tillering ability is weak, the whole growth period is about 115 days; the total number of grains per panicle is 120, the seed setting rate is 80%; 1000-grain weight is 26 grams, medium photosensitivity and temperature, short-day high temperature growth is long, cold resistance in the later stage, and color is good. Moderately resistant to rice blast and susceptible to bacterial blight.

Yield performance 2000-2001 participated in the regional test of late rice varieties in Hubei Province. In 2000, the yield of 471.75 per mu increased by 4.92% compared with the control Shanyou 64, which was very significant. In 2001, the yield per mu was 517.05 kg, 4.66% higher than that of Shanyou 64. Analyzed by the Rice quality testing Center of the Ministry of Agriculture, the rate of brown rice is 79.4%, the rate of head rice is 62.2%, the rate of chalky grain is 19%, the size of chalkiness is 1.9%, the ratio of length to width is 3.1, the content of amylose is 24.1%, and the gel consistency is 51 mm. In 1999, it was rated as the third grade high quality rice in Hunan Province.

The key points of cultivation are as late rice in Changsha area, sowing around June 20, and the seedling age is no more than 30 days. Sparse sowing, uniform sowing, reasonable close planting, strengthen fertilizer and water management. Planting 80, 000 basic seedlings per mu, the total number of seedlings per mu reached 300000, and began to dry the field. Heavy fertilization promotes tillering in the early stage and less application in the later stage to prevent lodging. Focus on the control of rice blast, sheath blight and bacterial blight.

Due to the differences in ecological conditions in different places, please follow the specific guidance of the local agricultural technology department.

Suitable areas are suitable for Hunan, Hubei, Guizhou, Guangxi and other provinces and regions, mountain areas, hills, plains can be planted. This variety is a national control variety and has a wide range of adaptability.
