摘　　要： [目的]为宁夏灌区花生生产提供理论依据。[方法]2014—2016年引进24份国内花生种质资源,在宁夏引黄灌区进行农艺、产量、抗病以及生物学等性状鉴定。[结果]整个生育期内鉴定品种病虫害较轻,株高、分枝数随品种的不同而不同。单株结果数5~52个,平均22.4个,饱果数占69.46%;百仁重51.7~108.4 g,属大中型果粒;出仁率65.21%~76.52%。相关分析表明,单株产量与株高呈显著正相关,与单株结果数、饱果数呈极显著正相关。产量0.64~4.11 t/hm^2,产量前4位的品种为天府18号、冀花11号、冀花7号、黑花生,均较对照(鲁花11号3.19 t/hm^2)增产,增幅8.78%~28.84%。[结论]筛选出了较适宜宁夏灌区种植的花生品种资源7份。 [Objective] To provide theoretical basis for practical production of peanuts in Ningxia irrigation area. [Methods]Agronomic traits, yield, disease resistance and biology characters were identified on 24 domestic peanut varieties introduced from 2014 to 2016 in Ningxia irrigation area. [Results] The results showed that diseases and insect pests in growth period were slight, and different varieties had different height and branch numbers. The peanuts number per plant ranged from 5 to 52 with the average of 22.4 and full fruit rate accounted for 69.46%. The 100-kernel weight ranged between 51.7 g and 108.4 g, indicating the fruits belonged to large or medium-sized class. Kernel content was from 65.21% to 76.52%.Correlation analysis showed that the yield per plant was significantly positively related to height, numbers per plant and full numbers. Yield ranged from 0.64 to 4.11 t/hm^2, with the top four varieties ＂Tianfu＂ No.18, ＂Jihua＂ No.11, ＂Jihua＂ No.7 and black peanuts, all of which were higher than ＂Luhua＂ No.11（3.19 t/hm^2）, 8.78% to 28.84% higher. [Conclusion]According to the results, seven varieties of peanuts suitable for planting in Ningxia irrigation area were selected.
