Stability and Adaptability Analysis of Yuzagu No.2 in the Spring-sowing Region
摘要
Abstract
In order to comprehensively understand the production characteristics of Yuzagu No.2 in the spring-sowing region,the agronomic traits,yield performance and stress resistance of Yuzagu No.2 were analysed based on the results of the national joint appraisal test of the foxtail millet variety re-gional adaptability from 2020 to 2021.The results showed that the variety exhibited good adaptability in the Early-Maturing Spring-Sowing Region of Northwest and Spring-Sowing Region of Northeast.Traits such as plant height and panicle length were stable.The yield performance was outstanding.The average yield in the Early-Maturing Spring-Sowing Region of Northwest reached 6 747.9 kg/hm2,with an increase of 8.67%compared with the control;In the Spring-Sowing Region of Northeast,it was 5 441.0 kg/hm2,with an increase of 7.53%compared with the control.Stability analysis showed that the mean-coefficient of variation and Shukla coefficient of variation were higher than or equivalent to those of the control,and the AMMI model stability parameter Dg was bigger than that of the con-trol varieties.However,its average high stability coefficient(HSC)was better than the control,a-chieving a balance between high yield and stable yield.In terms of adaptability,the yield-increasing point rates of Yuzagu No.2 in the Early-Maturing Spring-Sowing Region of Northwest and Spring-So-wing Region of Northeast were 76.92%and 77.27%respectively,and the adaptation degrees reached 84.62%and 72.73%respectively.In addition,the variety had strong comprehensive stress resistance and is suitable for simplified cultivation.In conclusion,Yuzagu No.2 had excellent characteristics such as high and stable yield,wide adaptability and multiple resistances,and had broad popularization and application potential in the spring-sowing region.关键词
