Breeding Report on the Winter Wheat Variety Tianxuan 79 with Resistance to Stripe Rust and High Yield
摘要
Abstract
In order to breed winter wheat varieties with disease resistance,high yield and wide adaptability suitable for planting in Longnan wheat area and similar areas in Gansu Province,Tianshui Institute of Agricultural Sciences carried out sexual hybridization with self-bred line 00127-2-2-3 as female parent and Zhoumai 22 as male parent.After years of continuous pedigree selection of hybrid offspring,a new winter wheat variety Tianxuan 79 with high yield and resistance to stripe rust was bred.During 2019-2021,it participated in the regional test of Longnan area in Gansu Province.The average yield of 10 points in 2 years was 7 437.90 kg/ha,which was 6.87%higher than that of the control variety Lantian 33.From 2021 to 2022,data from the production test showed that the average yield of 5 pilot sites was 6 910.35 kg/ha,which was 3.25%higher than that of the control variety Lantian 33.The plant height of this variety is 78.4 cm,the panicle length is 8.0 cm,the number of grains per panicle is 40.96,the grains are white and hard,the 1000-grain weight is 46.31 g,and the number of effective panicles is 5.7 million/ha.It has the characteristics of stripe rust resistance,stable yield and lodging resistance,and is suitable for planting in the low altitude areas of the Weihe River channel area in Tianshui,Gansu Province and the wheat area in Longnan.关键词
