Comparative Test of New Peanut Strains in Xuchang Pilot in 2022
To identify the best peanut strains suitable for cultivation in the Xuchang area,a comparative test of new peanut strains was conducted in 2022.The results showed that the strains W1552,W1503,H155,and H306 demonstrated good overall performance and strong disease resistance.The pod yields were 7 612.3,7 534.6,7 419.5,7 189.4 kg/ha,respectively,while the grain yields were 5 553.7,5 668.9,4 944.4,5 152.7 kg/ha,respectively.The oleic acid content of strains W1552 and W1503 was 33.72%and 33.01%,respectively,which makes them suitable as low oleic acid peanut varieties for promotion and planting.Conversely,the oleic acid content of strains H155 and H306 was 80.18%and 77.77%,respectively,making them suitable as high oleic acid peanut varieties for promotion and planting.
