Detailed Introduction to the Jiuqi Xiang No. 1 Rice Variety

Edible Gardening 0 views
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

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 cm, 200,000 effective panicles per mu, an average of 150 grains per panicle, and a seed-setting rate of 80-90%. The 1000-grain weight is 16 g. The rice quality has been nationally assessed as special-grade rice, comparable to the top-grade Thai fragrant rice from abroad. The total resistance frequency to rice blast is 90%. The resistance frequency to both IB and IC groups is 100%. Resistance to bacterial leaf blight is grade 9. The average yield per mu for a single season is 380 kg, and the highest yield in trial planting reached 513 kg. This variety has been the fastest-growing, most widely planted, most widely planted, and most significantly income-increasing in the Zengcheng area in recent years. The "Gualu Brand" nutritional health rice processed from this paddy received the '@#@119@#@ Gold Award' at the '99 Second Asian International Famous, Excellent, New Products, New Technologies, and New Inventions Expo, and the special-grade simiao rice was recognized as a Chinese famous-brand product at the '99 Fourth China International Agricultural Expo.
