摘要
为全面了解豫杂谷2号在春谷区的生产特性,依据2020—2021年全国谷子品种区域适应性联合鉴定试验结果,对豫杂谷2号在春谷区的农艺性状、产量表现及抗逆性进行分析。结果表明,豫杂谷2号在西北春谷早熟区和东北春谷区表现出良好的适应性,其中株高、穗长等性状稳定。产量表现突出,在西北春谷早熟区平均产量达6747.9 kg/hm^(2),较对照增产8.67%;东北春谷区为5441.0 kg/hm^(2),较对照增产7.53%。稳定性分析显示,均值-变异系数和Shukla变异系数高于对照或与其相当,AMMI模型稳定性参数(Dg)均大于对照品种,但各生态区平均高稳系数(HSC)优于对照,实现了丰产与稳产的良好平衡。适应性方面,豫杂谷2号在西北春谷早熟区和东北春谷区的增产点率分别为76.92%和77.27%,适应度分别为84.62%和72.73%。此外,豫杂谷2号综合抗逆性强,适宜轻简化栽培。综上表明,豫杂谷2号兼具高产稳产、广适多抗等优良特性,在春谷区具有巨大的推广与应用潜力。
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 regional adaptability from^(2)020 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 6747.9 kg/hm^(2),with an increase of 8.67%compared with the control;In the Spring-Sowing Region of Northeast,it was 5441.0 kg/hm^(2),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 control varieties.However,its average high stability coefficient(HSC)was better than the control,achieving 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-Sowing 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.
