Breeding Report on the New Winter Wheat Variety Tianxuan 83 with Stripe Rust Resistance and High Yield
摘要
Abstract
In view of the fact that the disease resistance of wheat varieties in Longnan,the northwest oversummering source ar-ea of stripe rust in China,is highly susceptible to breakdown,which poses a continuous threat to the safe production of wheat in the re-gion,in this study,the triticale derivative line 9913-1-1-2 was used as the female parent,and the self-bred high-yield germplasm 00155-5-1-2-1 was used as the male parent for hybridization.Using the technical system combining conventional pedigree selection and molecular marker-assisted selection,a new winter wheat variety Tianxuan 83 with disease resistance and high yield was bred through multi-generation directional selection and identification.The average equivalent yield of this variety in 2 a was 7 095.30 kg/ha,which was 6.01%higher than that of the control Lantian 33 in the regional experiment of winter wheat for the river valley area group of Longnan in Gansu Province,2021 to 2023.In the 2023 to 2024 production experiment of winter wheat for the river valley area group of Longnan in Gansu Province,the average equivalent yield was 6 734.76 kg/ha,which was 5.40%higher than that of the control Lantian 33.Test results showed that the grain protein content was 142.0g/kg,the wet gluten content was 317.0 g/kg,the sedimentation index was 16.5 mL,the dough stability time was 1.4 min,and the quality index reached the standard of high-quality medium gluten wheat.At the adult plant stage,it exhibited immunity to stripe rust physiological races such as Tiaozhong 32,Tiaozhong 33,and Tiaozhong 34.In areas at an altitude of 2 100 m,the overwintering survival rate of Tianxuan 83 was 89.45%to 90.55%,and it is suitable for culti-vation in the river valley areas of the Longnan wheat-growing region with an annual precipitation of 450 to 600 mm.Timely sowing from October 10 to 20,together with combined application of nitrogen and phosphorus fertilizers,water regulation at critical growth stages,and timely prevention and control of diseases and pests,can maximize the varietal potential.The successful breeding of this va-riety provides a theoretical basis and technical guidance for disease-resistant breeding and sustainable production of winter wheat in the river valley area of Longnan,Gansu.关键词
