Correlation Analysis of Agronomic Characters and Yield of New Wheat Variety Xinmai 58
[Objective] The aim was to provide scientific basis for the popularization of a new wheat variety Xinmai 58 with high quality and strong glutenin the southern wheat area of Huang-Huai-Hai. [ Method] Based on the data of regional test and production test of Water Land Group in south Huang-Huai-Hai area of the national winter wheat variety test from 2019 to 2022, we analyzed the agronomic characters and quality, yield composition, yield and correlation of Xinmai 58. [Result] The heading rate of Xinmai 58 was higher in the 3-year experiment of Water Land Group in south Huang-Huai-Hai. The effective panicle number was 6385900 panicles/hm2 with 33.90 grains per ear, 43.44 g thousand-grain weight, 9264.6 kg/hm2 average yield of production test. The yield was 5.68％ higher than that of the control, and the increase point rate was 100％. The quality result reached the quality standard of strong gluten wheat. The quality result reached the quality standard of strong gluten wheat. The correlation of three factors of yield and direct path coefficient showed that grains per ear was the main factor affecting Xinmai 58. [ Conclusion] We should ensure proper effective ears, pay more attention to grains per ear, stabilize the 1000-grain weight, and further explore the high-yield potential of Xinmai 58.
