On May 26, with the sound of a Gong from ye Zhenqin, member of the Standing Committee of the Guangdong provincial Party committee, the finals of the first Guangdong agricultural science and Technology Innovation Contest - "Wen's Cup" Guangdong seed industry science and technology innovation contest hosted by the Guangdong agriculture and rural department was held in Guangzhou national modern agricultural science and technology innovation center. In this contest, a total of 10 teams were shortlisted for the finals. A total of 50 referees were selected from 11 provinces (autonomous regions and cities) in the competition. The "breeding technology of all male Hybrid Snakehead 'male snakehead No. 1' selected by PRFRI participated in the selection as the only aquatic seed industry project in the finals and was rated as" excellent project ".

Seeds are called agricultural "chips". This year, the No. 1 central document issued the general call for "fighting the seed industry" and issued top-level design and strategic deployment at the national level. Liu Yutao, director of Guangzhou National Agricultural Science and technology innovation center, said that the competition direction of this contest is the cutting-edge innovation basic research of the seed industry. Within one month after the notice was issued, more than 360 projects were attracted to sign up for the competition. After two rounds of strict selection, 10 projects finally entered the finals, covering the whole chain of "big seed industry" such as planting industry, breeding industry and processing industry.

PRFRI is the pioneer of seed industry in Guangdong Province. In 1958, Mr. Zhong Lin of PRFRI overcame the world problem of "artificial reproduction of domestic fish", ended the history of human relying on rivers to catch natural fish and flowers, and opened the brilliant history of seed industry in Guangdong. Generation after generation of scientific researchers of PRFRI have continued to deeply cultivate the freshwater seed industry along the road opened by Mr. Zhong Lin, made remarkable achievements in the development of new breeding objects and improved seed cultivation, and made important contributions to Guangdong's aquatic seed industry leading the country. PRFRI has successively introduced and developed new objects such as tilapia, Macrobrachium rosenbergii, Silurus meridionalis, California perch, gem perch, pointed pond snakehead, American shad, silk tailed shad and Basa fish to the whole country. At the same time, it has made remarkable achievements in the cultivation and research of large and famous varieties of grass carp, tilapia, perch, snakehead, mandarin fish and Chinese soft shelled turtle, Eleven new aquatic varieties approved by the state were cultivated, including tilapia "Guangfu No. 1" and "Yuemin No. 1", big mouth bass "Youwei No. 1" and "Youwei No. 3", "black spotted Hybrid Snakehead", Chinese soft shelled turtle "Zhushui No. 1", cocked mandarin fish "Guangqing No. 1", Hehua carp "Ruyuan stone carp No. 1". The promotion of these new objects and varieties has improved the national aquaculture structure, greatly improved the economic, social and ecological benefits, and supported Guangdong to become the "world's largest freshwater fish seed industry base" to meet the needs of more than 60% of the country's aquatic seedlings.

The all male Hybrid Snakehead "male snakehead No. 1" was jointly bred by PRFRI and four units on the basis of the new variety of "black spotted Hybrid Snakehead" through molecular breeding and gender control technology, which solved the problems of slow growth, small individual and high feed coefficient of females in the breeding population, which seriously affected the economic benefits of breeding. After three consecutive years of pilot cultivation, the male rate of "male snakehead 1" is more than 93%, the overall growth rate is increased by more than 25%, the feed input of the same yield is reduced by 8-20%, the income per mu in the main production area of Guangdong is increased by 30000-50000 yuan, and the comprehensive benefit is increased by more than 40%. It is a revolutionary new breeding variety with grain, land, high value and high efficiency, It will play an important role in winning the turnaround of seed industry and Rural Revitalization Strategy.
