Screening and Identification of New Peanut Strains with High Yield and High Resistance in the South of China

In order to screen out the new peanut varieties with high yield, disease resistance and high quality suitable for being planted in the south of China, Zhanyou 75 was used as the control variety to identify the yield, quality and disease resistance of the 10 new peanut strains newly bred in the south of China. The results showed that the pod yield of Haikehua 181 and Fuhua 0945 respectively increased by 39.66% and 23.05% compared with that of Zhanyou 75, and the seed kernel yield respectively increased by 43.79% and 24.42% compared with that of Zhanyou 75, with extremely significant differences. Compared with Zhanyou 75, the pod yield of Quanhua 1478, Guihua 66 and Shanyou 121 increased significantly, but the seed kernel yield did not increase significantly, while the pod yield and seed kernel yield of Qianyoufense and Zhanyou 103 did not increase significantly. Qionghua 1104 had higher oleic acid content (70.12%). The protein content of Heyou 1079 was 29.43%, which reached the national high protein standard (28%). The drought resistance and flood resistance of all the tested peanut strains were strong, and the disease resistance level was medium. In consideration of the indexes such as the yield, field growth and resistance to disease, Haikehua 181 and Fuhua 0945 showed better overall performance and could be used for the small-scale planting demonstration experimentally. Qionghua 1104 could be used as the parent of high oleic acid material and Heyou 1079 could be used as the parent of high protein material.
