Abstract: In order to screen out the silage maize varieties suitable for planting in the central arid zone of Ningxia, in this experiment, 15 silage maize varieties were selected to be sown on May 3, 2021. All varieties were arranged in random blocks, with 3 replicates per variety, and each cell area was 24 m~2（4 m×6 m）, with a total of 45 cells. The experimental area was seeded by a roller seeder with a depth of 4-5 cm, plant spacing of 25 cm, row spacing of 50 cm, and planting density of about 80 000 plants/hm~2. During the growth period, the water needs to be supplemented by drip irrigation, 135 kg/hm~2 of diammonium phosphate and 600 kg/hm~2 of urea were applied throughout the year, and weeding was done manually twice. Harvest was carried out on September 6 after unified determination of the relevant indicators of each variety. After harvest, agronomic traits, yield traits and nutritional quality indexes, and RFV of 15 maize silage varieties were determined, and comprehensive evaluation was carried out by principal component analysis and affiliation function method. The results showed that the average plant height of the 15 varieties was 203.61 cm, among which the control variety（Zhengda 12） was 182.23 cm. The average fresh grass yield was 72.60 t/hm~2, and the fresh grass yield of varieties Datang 13 and Tunyu 168 was 90.90 t/hm~2 and 89.43 t/hm~2, respectively, which were significantly higher than those of other varieties（P＜0.05）. Except for the Datang 13, whose dry matter content was 29.71%, the dry matter content of rest of the varieties were ＞ 30.00%, of which the dry matter content of Xinyin KXA4574 was the highest, reaching 37.21%. The variety with the highest starch content was Runfeng 1602, which reached 42.53%, and the highest crude protein content was the variety Xinyin KXA4574, which reached 8.69%. Tunyu 168 had the lowest neutral detergent fiber and the highest RFV. The cumulative contribution of the first five principal components reached 88.673%, and the top two varieties ranked by the affiliation function were Datang 13 and Tunyu 168, respectively. The results indicated that Datang 13 and Tunyu 168 were outstanding in overall performance in this area and could be used as high-quality silage maize varieties.
