基于高稳系数和AMMI模型评价黄淮芝麻品种的产量稳定性OA

In order to screen out sesame varieties with high and stable yield suitable for planting in Huanghuai area,the results of regional test of new sesame varieties in China(Huanghuai area)from 2023 to 2024 were used as data sources,and seven tested sesame varieties(Shangzhi No.10,Zhu 22B07,Yuzhi No.4,Yuzhi 6801,Zhu 22B03,Xinzhi No.6 and Shangzhi No.11)were used as test varieties.Based on the high stability coefficient and AMMI model,the yield performance and stability of the tested sesame varieties in six test sites(Xinyang City,Nanyang City,Zhumadian City,Zhengzhou City,Suzhou City,Fuyang City)were comprehensively evaluated.The results showed that among the seven tested sesame varieties,the average yield of Shangzhi No.10 was the highest(1 542.15 kg/ha),followed by Zhu 22B07(1 519.96 kg/ha).Based on the analysis of high stability coefficient,the high stability coefficients of Xinzhi No.6,Zhu 22B03 and Zhu 22B07 were 86.18％,85.67％and 81.30％,respectively.Based on AMMI model analysis,the stability parameter of Yuzhi No.4 was the smallest(6.91),followed by Yuzhi 6801(12.39)and Zhu 22B07(12.59).In addition,the yield of sesame varieties was significantly affected by environment,variety and variety×environment interaction effects,and the cumulative contribution rate of IPCA1 and IPCA2 was 86.28％,which was the main source of variety×environment interaction.In summary,Zhu 22B07 had good yield level and stability in Huanghuai area,and was suitable for planting in Huanghuai area.
