Successful trial of new hybrid rice varieties of Honglian type

Just after the autumn harvest, news came from Jiangjin District in Chongqing that a new type of rice variety, Honglian Luoyou 10, was successfully planted in the area a few days ago. Without pesticide application, the average yield of this variety reached 600 kg per mu at the altitude of 400 meters and below, 400 to 600 meters and more than 600 meters, and there were no diseases and insect pests such as rice blast, rice false smut, sheath blight and bacterial blight.

Honglian Luoyou hybrid rice is the latest scientific research achievement of Zhu Ying, academician of the Chinese Academy of Engineering and Professor Zhu Ying of the Academy of Life Sciences of Wuhan University. It is a stable ecological variety with wide adaptability, multi-resistance, high temperature tolerance, high nitrogen efficiency, high selenium adsorption, economy and high efficiency. It is suitable for mechanized and light cultivation. Different from other hybrid rice varieties, this variety can also achieve the goal of high yield through intensive cultivation under special ecological and climatic conditions. In 2016, the variety passed the variety approval in Hubei Province, and applied for the protection of new plant variety rights. According to Professor Zhu Ying, the variety was bred by the combination of molecular marker-assisted selection and conventional breeding, combined with directional selection at high temperature and low nitrogen. It has the characteristics of fertilizer saving, drug reduction, environmental friendliness, ecological efficiency and so on. It is suitable for light and simple cultivation. It is the first choice for the production of selenium-rich, ecological and organic rice, and has good economic and social benefits. (Tao Dawei reporter Feng Jing)
