Hunan Introduces Five Quality Hybrid Rice Varieties to Achieve New Breakthrough in Rice Breeding in China

On the 30th, Hunan, which is known as the "Kyushu granary," officially launched a new hybrid rice variety of 5 new rice varieties with high quality rice standards. The rice quality is comparable to that of Thai rice.

Liu Zonglin, director of the Hunan Provincial Agriculture Committee, said that these five high-quality hybrid rice varieties have achieved organic integration of yield, resistance, and quality, and solved the long-standing problem of “best but not abundance, excellent but not resistant” and ended. The history of high-quality rice cultivation, high risk, and low yield is another major breakthrough in China's rice breeding and is another major achievement of the agricultural research team represented by Academician Yuan Longpian.

As the nation's largest rice production province, Hunan has created splendid rice production and quality. Hunan is also the earliest province to develop high-quality rice. At the time, the “cat teeth rice” and “silk seedling rice” produced in the 1990s were very popular. However, due to changes in the situation of grain purchases and marketing, the development of high-quality rice has been intermittent, but also encountered the "not to sell Hunan rice today."

In order to reinvigorate Xiangmi, since the beginning of 2010, the Hunan Provincial Government has launched the project of “Doing Strong and Strong Xiangmei Industry”, and adhered to the three wheels of “selection and breeding, construction of bases, and development of enterprises” to strengthen the technological innovation. With the creation of the brand, a sound development pattern of “good planting good grain, good grain out of good rice, and good rice selling good price” has been formed.

Liu Zonglin introduced that in variety breeding, the province has successfully launched a new conventional rice variety with high quality rice, such as Xiangwanzao 17 and Yujiaxiang, which are the first rice varieties with quality standards. Today, the five new rice varieties are introduced again. A new hybrid rice variety with quality standard of the second-class second-class quality rice standard; in scale production, the standard base for high-grade high-quality rice has grown from more than 100 million mu to more than 3 million mu this year, extending from Pinghu District to high-altitude mountainous regions; In terms of cultivation, the high-quality rice output of the leading enterprises has increased year after year. The proportion of sales of high-quality rice has increased from less than 10% to more than 50% now. The annual sales volume of Hunan Grain Group has increased from 70,000 to 80,000 tons to more than 500,000 tons, and the high-quality rice accounted for 94%. %, among the top five food industry in the country.

According to Liu Zonglin, in order to upgrade the Xiangmi industry, the province has established a high-quality, high-quality rice variety breeding cooperative research group. It is composed of 9 outstanding breeding experts, and conducts on-the-spot assessments and field assessments every year to exchange and share germplasm resources. The Hunan Provincial Agriculture Committee has organized high-quality rice selection several times, collecting new varieties from the southern rice region, planting them uniformly, and grouting during the same period. The experts are invited to be screened by experts to perform rice appearance evaluation and taste evaluation.

The reporter learned that the five varieties released by the Food Quality Inspection Agency of the Ministry of Agriculture on the 30th, of which 2 were middle rice and 3 were late rice, were among the more than 300 varieties and could be widely promoted. The collection of "four good": First, good species. Mid-maturity or mid-maturity in the growing season is late, and sowing in mid-June, the normal year in the province can be safely eared. Rice blast disease has a high comprehensive resistance index, which is a kind of rice blast disease. It can be completely controlled and controlled in production. The average yield per hectare of two mid-season rice varieties was more than 600 kilograms, and the average yield of three late rice varieties was more than 500 kilograms, which was 20% higher than that of ordinary high-quality conventional rice. Second, it was delicious. According to experts' taste evaluation, the taste scores of these breeds ranged from 8.55 to 8.99 points, which was much higher than the 8.00 points of the Hunan high quality rice planted on a large area in Hunan Province on the 13th; the third was good-looking. The transparency of rice is Grade 1, and the chalkiness is 0.7%~1.7%. The appearance is crystal clear and translucent. The fourth is good processing. The rate of whole polished rice is 56.5%~66.2%, which is 3~13% higher than the high-quality and high-quality conventional rice widely promoted at present.

“Hunan as a major grain producing province in China will vigorously promote new varieties of high-quality hybrid rice and strive to reach 5 million mu in 2018. In 2020, the province will develop a standardized production base for high-quality high-quality rice to 15 million mu, ensuring that 80% of the quality of rice products is achieved. The country's first and second-class quality rice standards," Liu Zonglin told reporters.
