Analysis on Major Agronomic Traits and Yield of Huayu Series of Peanut Cultivars under Mulched Drip Irrigation

摘要

Objective] This study aimed to investigate the appearance of major agronomic traits and yield potential of Huayu se-ries of peanut cultivars under the condition of mulched drip irrigation, so as to provide core parent materials for new peanut cul-tivar breeding in Xinjiang during Thirteenth Five-Year Plan. [Method] A total of 16 peanut cultivars of Huayu series were studied systematical y 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 bet-ter 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 wel as yield, among different peanut cultivars. Among al 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 culti-vars’ comprehensive traits were excel ent. [Conclusion] In the high-yielding breeding of peanut in Xinjiang, Huayu 33 and Huayu 50 can be used as core parent materials. Under the condition of mulched drip irrigation, their yield potential can be further ex-plored.
