Abstract：This study aimed to identify the best peanut strains suitable for cultivation in Xuchang City,a comparative test of 13 new peanut strains was conducted in Changge City in 2024,the Yuhua 9326 was used as the control variety,and the growth period,main agronomic traits,disease situation,economic traits,fruit morphological and yield of the tested peanut strains(species)were investigated.The results showed that in terms of the growth periods,the whole growth periods of the strains C6601,C6602,C4160 and C6609 were shorter,and the whole growth periods of the strains C4210,C4253,C4212,C3465 and C4254 were longer.In terms of the main agronomic traits,the main stem height and lateral branch length of the strain C4212 were the longest,the total number of branches and the number of fruiting branches of the strain C6604 were the most,and the emergence rate of the strain C3454 was the highest.In terms of disease situation,the strains C4210,C4254 and C4212 showed mild resistance to net spot disease and leaf spot disease.In terms of economic traits,the strain C3465 had the highest full fruit rate,the strain C4254 had the highest 100-fruit weight and 100-kernel weight,the strain C4202 had the largest number of fruits per kilogram,the strain C4261 had the largest number of kernels per kilogram,the strain C4160 had the highest rice yield,and the strains C4212 and C4253 had higher single-plant productivity.In terms of yield,the pod yields of the strains C4212 and C4253 were both relatively high,reaching 539.62 and 527.18 kg/ha respectively.The seed kernel yields of the strains C4202,C4212 and C4253 were all relatively high,being 370.03,356.15 and 355.85 kg/ha respectively.In summary,the strains C4212,C4253 and C4202 have obvious advantages in high yield,stability and adaptability in Changge City,and are suitable for planting in Xuchang City and similar ecological areas.
