| Abstract: | 【Objective】 To select silage maize varieties suitable for planting in Aral region of Xinjiang.【Methods】 The nutritional components were determined in lab and the nine silage maize varieties and their nutritional quality was evaluated by RFV and grey correlation degree.【Results】 The results showed that there were significant differences in hay yield, CP (Crude protein), EE (Crude fat), ADF (Acid detergent fiber), NDF (Neutral detergent fiber), ash (Crude ash) and str (Starch) contents among nine silage maize varieties (P< 0.05); The fresh yield of Xinsiyu 12 was the highest up to 1.19×105 kg/hm2, the lowest NDF content was 51.87%. CP content of Xinwo No. 1 was the highest up to 7.60%, and the lowest ADF content was 28.53%. EE content of Jiyu 336 was the highest up to 3.16%, the lowest Ash content was to 6.06 %, and Str content was the highest up to 30.87%.【Conclusion】 According to the comprehensive evaluation of field performance and gray analysis, Huamu 3, Jiyu 336, Xinsiyu 11 and Tunyu 168 are suitable for cultivation and planting in Aral area. |
