Changmi 011

　　Our state’s rice planting area exceeds 1.5 million mu. Due to Liangshan’s distinct three-dimensional climate and significant diurnal temperature variations, the rice produced here is of superior quality, with high nutrient accumulation and high per-unit yield. Liangshan rice has long enjoyed an excellent reputation. Many locally bred and introduced varieties are grown, among which a considerable portion are national and provincial premium-quality rices. Changmi 011 is a grassy plant belonging to the Poaceae family and is an indica-type rice. It is a new variety bred in 1995 by the Liangshan Prefecture Agricultural Science Institute through complex hybridization using IR26/Chengdu Late Japonica // Romeo/Li Zha. In 1992, it won the first prize in the Indica Rice category at the inaugural Sichuan Province “Rice Fragrance Cup” awards. It is a provincial high-quality rice. This variety stands about 85 cm tall, has a growth period of 176–180 days, weak tillering ability, but a high effective panicle formation rate with many productive panicles. On average, it has 113 spikelets per panicle, 84 filled grains, and a setting rate of 74%, yielding over 500 kg per mu. The grains are slender, awnless, light yellow in color, with a brown rice rate of 81%, milled rice rate of 66.9%, and head rice rate of 63.5%. The rice grains are translucent and glossy with minimal chalkiness. The cooked rice is soft, does not harden when cooled, and has a sweet aftertaste, making it extremely palatable. Nutritionally, Changmi 011 contains 10.3% protein and 14% amylose, classifying it as a high-protein, low-amylose variety. Compared to other varieties, it generates an additional output value of 125.27 yuan per mu, and its price per jin is 20–30% higher. This variety is primarily grown in counties and cities such as Xichang and Dechang at elevations of 1,300–1,700 meters, with current planted area exceeding 5,000 mu. Its cultivation range is continuously expanding. (Xichang)
