Giant embryo rice enters the breeding method stage, blood pressure-lowering rice expected to reach the market
Red rice with anti-atherosclerosis properties and giant embryo rice with blood pressure-lowering functions have entered the laboratory breeding stage and are expected to reach people's dining tables in the near future. This is the news the reporter obtained yesterday at the opening ceremony of the "2007 Shanghai Science and Technology to the Countryside" series of service activities. It is reported that "high-protein rice breeding," undertaken by the Plant Molecular Genetics Laboratory of Shanghai Normal University, has been listed as a key project of the Municipal Science and Technology Commission. According to project leader Professor Li Jianyue of Shanghai Normal University, cultivating high-protein rice is of great significance in many respects.

Giant embryo rice has entered the laboratory breeding stage
Red rice with anti-atherosclerosis properties and giant embryo rice with blood pressure-lowering functions have entered the laboratory breeding stage and are expected to reach consumers' dining tables in the near future. The "high-protein rice breeding" project undertaken by the Plant Molecular Genetics Laboratory of Shanghai Normal University has been listed as a key project of the Shanghai Municipal Science and Technology Commission. Red rice is a natural colored rice that has anti-atherosclerosis properties and can enhance the body's antioxidant capacity. It is rich in bioactive substances such as carotene, flavonoids and alkaloids, as well as mineral elements including iron, zinc and calcium. Scientific researchers have combined high-protein

Detailed Introduction to the Jiuqi Xiang No. 1 Rice Variety
Jiuqi Xiang No. 1 rice was independently developed by the Zengcheng Agricultural Science Research Institute as part of the Guangzhou Science and Technology Commission's "High-Quality Rice Breeding Experimental Project," the Ninth Five-Year Plan's "96-2-48-4" project. It was bred by crossing a mixed male parent of Basmati, Batai Zaoxiang, and Xiangsimiao varieties with Qingzhen 8 as the female parent. It is an early indica medium-maturity rice, and when planted in the late season it is a stable-yielding, high-quality, and efficient fragrant soft simiao-type variety (when planted in the early season, it sprouts on the panicle). The full growth period is 125 days in the early season and 110 days in the late season, with a plant height of 100

Key High-Yield Transplanting Techniques for Rice Variety Xinyou 205 in Jinggu County
Xinyou 205 is one of the main rice varieties promoted under the 2010 Science and Technology Demonstration County Project in Jinggu County. The following technical points should be noted during transplanting: 1. Field preparation: the field must be plowed three times and harrowed finely, with the field level and the soil turned to mud. 2. Fertilization: apply 1000-2000 kg of decomposed farmyard manure deeply per mu, 40 kg of compound fertilizer in the middle layer, and 10-15 kg of potassium sulfate or potassium nitrate. 3. Transplanting time and density: the transplanting period is mid-April, and transplanting should be done on the second day after field preparation, with seedling age of 40-45 days.

How to grow direct-seeded rice? Experience shared by Jingtoushan Farm
Our farm has nearly 700 hectares of paddy fields. We began direct seeding of rice in 1987 and fully promoted it starting in 1999, with a 100% success rate. The key points of this direct seeding technique are mastering the following three critical stages. 1. Land preparation stage. Plow the paddy field, break up the soil, and irrigate; either machine leveling or oxen leveling will do. Then use a leveling bar to smooth the field flat. Use a homemade ditching board to open the furrows. The ditching board is 2 m long, 45 cm wide, and 3 cm thick. On the wooden board, nail 2 handles on each side, each 30 cm long, with a width of 1.6 m between the handles, for attaching ox harness ropes

Introduction to the Jingchuyou 148 Rice Variety
Jingchuyou 148 is a hybrid late rice variety developed by the Jingzhou Seed Company by crossing the male sterile line "Jingchu 814A" with the restorer line "R148". It was approved by the Hubei Provincial Crop Variety Approval Committee in 2002 (variety approval number 017-2002), and in 2003 was designated by the Hubei Provincial Department of Agriculture as a main recommended variety. The variety participated in the Hubei Provincial hybrid late rice variety regional trials in 2000-2001. In the 2000 regional trial, it showed obvious advantages in rice quality, yield, growth period, comprehensive agronomic traits and other aspects.
