Abstract: 【Objective】 To analyze the yield potential and adaptability of Xinyu108, a new direct - harvesting maize hybrid with early - mid maturity, and to provide a scientific basis for its extension. 【 Method】Based on the regional test, production test and multi - point test results of early - mid maturity spring maize sown in northern Xinjiang, RCT99 software was used for statistical analysis. 【 Result】 The average yield of the two - year regional trial was 953. 5 kg / 667 m² , 5. 89% higher than that of the control Denghai 3672. The rate of increasing production point was 89% . The yield of production test was 907 kg / 667 m² , which increased by 2. 97% compared with the control. The rate of increasing production point was 80% . The average output was 1,103.4 kg/667 m², and the high-yield field production reached to 1,327 kg/667 m².The average growth period was 120. 1 days, 0. 45 days earlier than that of the control, and the effective accumulated temperature needed was 2, 500℃ ( ≥10℃ ) . Grain bulk density was 782 g/L, crude protein 9. 6% , crude fat 3. 5% , and crude starch 75. 49% . The lodging and breakage rate was 1. 2% , the moisture content was 23. 7% , the damage rate of machine - harvested grains was 3. 78% , the ear - drop rate was 0, the grain - drop rate was 0.7% , and the yield loss rate was 0. 7% . The drought tolerance index is 0.95, which ranked strong tolerance level as same as Xianyu 335 and has two grades of drought tolerance than Zhengdan 958. The density is good with density index of 1.12.【 Conclusion】 Xinyu108 has high yield, good stability, good quality, fast dehydration, lodging resistance, resistance to maize smut, head smut and stem rot, and is suitable for mechanical harvesting.

Key words: early-mid maturity maize; grain harvesting by machine; yield; stress resistance
