The early maturing hybrid rice combination “Minghui 77” from Qianghui was characterized by its strong combination of high yield, blast resistance, suitable growth period, wide adaptability, easy seed production and better quality of rice. The combination to participate in the national regional test, the average yield increased by 8% Wei than 64%. In the provinces of Hunan, Guangdong, Guangxi, Jiangxi, Hubei and Fujian, a total of 1,433,300 hm2 was promoted, with a cumulative increase of 1,009 million kg of grain. In recent years, the annual promotion area of 333,300 hm2 or more, become China’s rice planting areas of early maturing hybrid rice one of the main combinations.
