Successful breeding of new wheat varieties with high quality and weak gluten in China

Introduction: according to the American Association for food and agricultural policy research According to the news from the Wheat Research Institute of Henan Academy of Agricultural Sciences, the project of "Research on the selection of new high quality weak gluten biscuit pastry wheat varieties and their high-efficiency cultivation techniques" undertaken by Zhengzhou branch of National Wheat Improvement Center, Anhui Agricultural University, Hubei Academy of Agricultural Sciences and other scientific research institutions and enterprises has been a breakthrough in the selection of several new varieties, and two varieties have passed Approved by experts TBP reported that the total annual wheat consumption in China is 105 million tons, including 39.5 million tons of commercial wheat, while the consumption of standard weak gluten wheat in China is 3.5 million tons, which is expected to be 3.6 million tons in 2005 However, there are few high-quality weak gluten wheat planted in China, and all the raw materials needed by flour and food processing enterprises to produce high-grade biscuits and pastries are basically imported Therefore, it is of great significance to research and develop high-quality weak gluten wheat varieties, to promote the standardized production of high-quality weak gluten in China, to meet the market demand, to promote the adjustment of agricultural structure, and to achieve high-quality and efficient agricultural production The project leader said that during the implementation process, two new varieties of high-quality weak tendons have been approved by Henan Province and Anhui Province respectively, namely space5 and Annong 98005 Space 5 is a new wheat variety with high quality, high yield and weak gluten, which was selected by Zhengzhou branch of national wheat improvement center with space mutation breeding technology It is also the first new wheat variety successfully selected and approved by China with space mutation breeding technology In Henan Province, the yield of Yumai 18 was 5.33% higher than that of Yumai 18, ranking first, and its quality was better All the indexes reached the national standard of weak gluten wheat with high quality Annong 98005 is a new wheat variety with high yield, high quality and weak gluten, which was bred by the Department of agronomy of Anhui Agricultural University In the regional test of spring water group in the south of Huanghuai River, the yield of Annong 98005 is 8.8% higher than that of Yumai 18, and the average yield per mu is 447.1 kg All indexes meet the standard of weak gluten wheat (GB / 17320-1998) According to TBP, there is also a new high-quality weak gluten line Zhengmai 004 in the implementation of the project, which has outstanding performance in the national and Henan regional trials Zhengmai 004 participated in the multi-point yield ratio test, with an average yield of 521.1kg per mu, 7.3% higher than that of Yumai 49, reaching a significant level It has high resistance to stripe rust and leaf rust, medium resistance to powdery mildew and leaf blight Through the analysis of sedimentation value, wet gluten, farinograph and other indicators, it has reached the national standard of high-quality weak gluten wheat In addition, three new high-quality weak gluten lines, Annong 0305, Zhengmai 2441 and 94661, have been successfully selected and are participating in the provincial pilot test and multi-point comparison test.
