Abstract：This study aimed to screen high‑yield and stable‑yield sesame varieties suitable for planting in Zhoukou City,a comparative test of 12 new sesame strains was carried out in Zhoukou City in 2024.The grey correlation analysis method was used to comprehensively evaluate the 10 agronomic traits(equivalent yield,plant height,initial capsule height,empty slightly length,fruit axis length,capsule number per plant,number of seeds per capsule,thousand‑grain weight,whole growth period and stem spot blight disease index)of the 12 new sesame strains.The results showed that,from the perspective of agronomic traits,empty slightly length,stem spot blight disease index and yield were the key factors affecting the comprehensive performance of the sesame strains,and the cumulative weight exceeded 70.00%.From the perspective of sesame strains,the sesame strains P3,P8 and P9 showed better comprehensive performance.Among them,the sesame strain P3 had a yield of 1 396.80 kg/ha,which was 24.50%higher than that of the sesame strain P1.In summary,in the process of sesame breeding,the varieties with shorter empty slightly length,stronger disease resistance and higher yield should be selected.
