[Method] A total of 16 peanut cultivars of Huayu series were studied systematically by field experiment and laboratory analysis. In addition, the main stem height, lateral branch length, pod number per plant, 100-pod weight, 100-kernel weight, pod length, pod width and yield of different peanut cultivar were compared. [Result]Under the condition of mulched drip irrigation, the appearance of major agronomic traits of peanut cultivars in Xinjiang was better than that in Shandong areas. In Xinjiang, the yields of the peanut cultivars were increased in varying degrees. However,there were some differences in appearance of major agronomic traits, as well as yield, among different peanut cultivars. Among all the peanut cultivars, the single-plant productivities of Huayu 22, Huayu 28 and Huayu 50 were higher than those of the other cultivars, and the yields of Huayu 33 and Huayu 50 were higher than those of the other cultivars. Meanwhile, the late two cultivars' comprehensive traits were excellent. [Conclusion] In the high-yielding breeding of peanut in Xinjiang, Huayu 33 and Huayu50 can be used as core parent materials. Under the condition of mulched drip irrigation, their yield potential can be further explored.展开更多
