Abstract:
In order to screen out the new varieties of peanut which were suitable for being planted in Fuqing City with high yield, disease resistance and good quality, 13 new varieties of peanut were introduced in the spring of 2020 for the comparative test. By taking Quanhua No.7 as the control group, the agronomic characters, high yield, stress resistance and adaptability of the tested varieties of peanut were comprehensively compared. The results showed that the pod yield of Quanhua 1104 and Quanhua No.21 was 16.06% and 8.75% higher than that of the control group, respectively, and the yield of seed kernel was 34.72% and 14.34% higher than that of the control group, with extremely significant differences. Compared with the control group Quanhua No.7, the pod yield of Quanhua 1439 and Quanhua 1112 was significantly increase; the seed kernel yield of Quanhua 1439 was extremely significantly increased, while the seed kernel yield of Quanhua 1112 was increased but not significantly; the pod yield of Quanhua No.23, Quanhua 1306 and Quanhua No.17 were increased but not significantly. The seed kernel yield of Quanhua No.23 was significantly increased, the seed kernel yield of Quanhua 1306 was significantly increased, and the seed kernel yield of Quanhua No.17 was not significantly increased. However, the pod yield of Quanhua No.20 decreased but not significantly, while the seed kernel yield of it increased significantly. Except for the weak drought resistance of Quanhua 1306 and Quanhua No.23, the growth potential and stress resistance of all the tested varieties of peanut were medium or strong. The protein content of Quanhua 1104 and Quanhua 1439 was 28.08% and 28.48%, respectively, which reached the national standard of high protein (28%). The oil content of Quanhua No.21 and Quanhua No.23 was 56.97% and 58.86%, respectively. Through the comprehensive comparison of the yield, stress resistance and adaptability of the tested varieties of peanut, Quanhua 1104 and Quanhua No.21 could be planted in a small area next year; Quanhua 1439 and Quanhua 1112 could continue to be tested, while Quanhua No.23, Quanhua 1306 and Quanhua No.17 could continue to be observed and planted next year.
