It is necessary to select seeds for farmers.

On the morning of September 6th, the 2016 national exhibition and exchange meeting of new high-quality and high-yield rice varieties was held in Hefei, Anhui Province. More than 150 technical experts from the middle and lower reaches of the Yangtze River in the National Rice Regional trial and relevant provincial rice variety testing officials, together with more than 200 rice growers, dealers, members of the rice professional committee, and rice experts, came to Shitang Town, Feidong County, Hefei City, Anhui Province to observe the rice varieties.

"in order to build a strong agricultural province, the Anhui Provincial Agricultural Committee and provincial government has always regarded the crop seed industry as a basic and strategic core industry." Xiong Chengguo, director of Anhui seed Management Station, told reporters, "by the end of 2015, the number of seed enterprises in Anhui Province had decreased from 479 in 2010 to 254, the industrial capital had increased from 1.4 billion to more than 4 billion, and the annual production and operation of all kinds of improved varieties had reached 2 billion jin. Sales income is 5.8 billion yuan. There are more than 40 enterprises in Kaizhong breeding innovation work in the province, with an annual investment of 200 million yuan in scientific research. "

With the increasing investment in scientific research, farmers pay more and more attention to the stability and adaptability of rice. "I ask my variety to have no obvious shortcomings, not only to resist high temperature, but also to resist low temperature, but also to resist all kinds of diseases and insect pests, to be adaptable and to adapt to a wide range of areas." Chen Liyun, a professor at Hunan Agricultural University, said at the exchange meeting, "for example, the variety of'C Liangyouhuazhan 'has been approved and can be planted in the upper and middle and lower reaches of the Yangtze River."

"'C Liangyouhuazhan'is a new indica hybrid rice combination with high quality, high yield, high resistance and stable yield, which has the characteristics of strong tillering ability, good stem toughness and moderate plant type." Zhang Zhengguo, vice chairman of the Rice Professional Committee of the National crop Variety approval Committee, commented, "this variety has a wide adaptability and is a good variety with market promotion potential."

"at present, the general trend of rice breeding is heterosis plus ideal plant type, and multi-panicle coincides with this trend." Qian Qian, deputy director of the China Rice Research Institute, said, "We should follow the trend and follow the experience summed up by experienced old scientific and veteran breeders for a long time."

With good varieties, it is also necessary to have matching production and cultivation techniques. Zhang Xiufu, a researcher at the China Rice Research Institute, said when introducing the high-yield cultivation techniques of "C Liangyouhuazhan": "now rice cultivation must be standardized, simplified, and modernized."

After observing and discussing the new rice varieties with high quality and high yield, more than 150 national rice regional test technical experts and responsible persons attended the national rice experimental technology training course. "Why is it necessary to conduct variety testing and variety approval?" Ma Zhiqiang, director of the Variety Department of the seed Administration of the Ministry of Agriculture, introduced the revision of the measures for the examination and approval of Major crop varieties: "this work is carried out to ensure the safety of varieties in production and to check the selection of varieties for farmers. in order to avoid and reduce as much as possible no major losses in actual production, varieties used in production should not have serious defects." "the importance of improved varieties in agriculture is self-evident. Strong farmers must first strengthen seeds, and improved varieties account for more than 43% of the increase in agricultural production. " Luo Zhixiang, deputy director of the Rice Research Institute of Anhui Academy of Agricultural Sciences, said when explaining the field test methods and techniques of rice variety test, "Variety test is an important link in variety upgrading and provides a scientific basis for variety examination and approval." In addition, Wang Shufeng, an associate researcher at the Beijing Agricultural Information Technology Research Center, introduced the research and application of information collection technology for rice variety regional trials.
