Abstract:

【Objective】 To analyze the yield potential and mechanical harvest performance of a new maize hybrid Xinyu 110 with very early maturity in the hope of providing a scientific basis for the promotion of the new variety.【Methods】 Taking the regional trial of very early maize as second crop in southern Xinjiang as materials, the statistical analysis system of crop varieties regional trial RCT99 was used.【Results】 The output of Xinyu 110 was 522.27 kg/667m2 in the regional trial, which was 12.13% higher than that of the control Xinyu 10. The production test was 552.67 kg/667m2, which was 17.01% higher than that of the control. The growth period was 87.9 days, 2.9 days earlier than the control. The unit weight of grain was 768 g/L, the crude protein content was 9.9%, the crude starch content was 74.92%, and the crude fat content was 4.6%. It obtained lodging resistance, resistance to maize smut, head smut, and rough shrinkage. The bracts open naturally at maturity and dehydration was fast.【Conclusion】 Xinyu 110 has high output and great potential for increasing production. It belongs to strong heterosishybrid with very early maturity, good quality as well as wide adaptability. It is suitable for replanting after wheat in southern Xinjiang and spring planting in cold areas of northern Xinjiang. It requires the effective accumulated temperature 2,200℃ above 10℃ and suitable for mechanical harvesting of kernels.
