Excellent varieties make dining tables more diverse for the masses
2023-06-06
This year, the No. 1 central document of the Central Committee proposed to establish the concept of "big food" and accelerate the construction of a diversified food supply system that integrates food, economy and feed, combines agriculture, forestry, animal husbandry and fishery, and combines plants, animals and microorganisms. From eating fully to eating healthily and abundantly, good breeding is indispensable. How to accelerate the cultivation of diversified varieties to meet the constantly upgrading demand of the masses for dining tables? The reporter conducted an interview. The "Vegetable Basket" has more new varieties. At 8 am, it is located at the Hanjiawan Aquaculture Base by Liangzi Lake in Jiangxia District, Wuhan City, Hubei Province. As soon as the automatic feeding machine is turned on, schools of fish flock to it. Farmer Han Ming'an said that this batch of Wuchang fish is expected to go public in August and September of this year, with a profit expected to reach 1800 yuan per acre. The scientific name of Wuchang fish is the round head bream, commonly known as the bream. Its meat is delicious and nutritious, making it one of the important freshwater aquaculture fish in China. Due to factors such as inbreeding, the germplasm of blunted bream in various regions has deteriorated, its growth rate has slowed down, and its body shape has become shorter and thicker. "Professor Wang Weimin from the School of Fisheries at Huazhong Agricultural University said that since 2008, the scientific research team has collaborated with Yangxin County Bairong Aquatic Products Co., Ltd. and other companies to adopt family selection, group selection, and fish parent-child identification techniques, continuously breeding for four generations, and testing has been conducted in multiple parts of the country, Finally, in 2017, a new round head bream variety "Huahai 1" with strong disease resistance and fast growth speed was successfully bred. The new variety can grow to a pound and a half in just over a year, with thicker meat and good transportation resistance. It can be marketed in a staggered manner one to two months in advance. "Han Ming'an said that the base currently has over 50000 head breams, and last year, the net profit from selling fresh fish was over 90000 yuan. Breeding high-quality aquatic products to bring more fresh fish and shrimp to the table. Across the country, a total of 266 new aquatic species have been announced, and the Ministry of Agriculture and Rural Affairs has also launched the National Aquatic Breeding Joint Research Program this year to strengthen the security guarantee of aquatic species sources in China. China is a major producer and consumer of edible mushrooms. Li Feng, Director of the Edible Fungi Research Institute of the Xinxiang Academy of Agricultural Sciences in Henan Province, introduced that in order to adapt to the production and market consumption needs of edible mushrooms, the team has selected more than 60 excellent new varieties of the "New Family" series of Pleurotus and Pleurotus through hybridization and molecular methods, and has obtained 21 plant new variety rights protection varieties from the Ministry of Agriculture and Rural Affairs. At the Jitun Edible Mushroom Planting Professional Cooperative in Huixian City, Xinxiang City, the thick stacked umbrella covers of mushroom mushrooms are propped up one after another. This variety is called 'Pinggu 108', which is a new variety cultivated by the Academy of Agricultural Sciences. It not only has a beautiful flower shape, but also has a high conversion rate. One kilogram of dry material can produce one kilogram and two liang of mushrooms, and five crops can be harvested within six months. "Wang Linning, the chairman of the cooperative, said that with the support of the Academy of Agricultural Sciences and technology, the cooperative produces nearly 3 million kilograms of edible mushrooms annually, mainly sold to Beijing, Henan, and other places, with a total revenue of over ten million yuan. Behind the increasingly abundant "vegetable basket" are generations of updated and excellent varieties. Last year, four national edible mushroom germplasm resource banks were selected as the first batch of national agricultural microbial germplasm resource banks, providing strong support for the preservation and utilization of high-quality mushroom resources and the growth of the edible mushroom industry. In terms of vegetables, the coverage rate of major vegetable varieties in China's main production areas has reached 96%, while the coverage rate of domestic variety production is 87%. The support capacity of vegetable breeding for the industry is constantly increasing. Innovative industry, academia, and research
