摘要: 为了解国审玉米新品种‘浚单996’的生产特性和推广应用价值,根据2019—2020年黄淮海夏玉米区域试验、生产试验资料,利用产量平均值法、变异系数法、高稳系数法和回归系数法等多种方法,对‘浚单996’的丰产性、稳产性和适应性进行统计分析。结果表明,‘浚单996’2年区域试验平均产量和生产试验产量分别为10431.8 kg/hm2 和9904.5 kg/hm2,较对照‘郑单958’分别增产3.6%和4.6%。2年区域试验中,‘浚单996’产量变异系数分别为16.73%、12.91%,均低于对照;高稳系数分别为78.29%、82.21%,均高于对照;回归系数分别为0.9440、0.9398,均小于1且低于对照;增产点率分别为64.1%、82.1%。从试验结果来看,‘浚单996’抗倒伏能力、抗病性、耐高温性比较好。综合分析,‘浚单996’是一个丰产稳产性好、适应性广、抗逆性强的玉米新品种,适宜在黄淮海夏播玉米区大面积推广种植。

Abstract:

In order to comprehensively understand the production characteristics and application value of the national approved maize variety ‘Xundan 996’, the high yield, stability and adaptability of ‘Xundan 996’ were statistically analyzed by means of yield average, coefficient of variation, high stability coefficient, and regression coefficient using the data of the regional test and production test in Huang-Huai-Hai summer maize area from 2019 to 2020. The results showed that the average regional trial yield and production trial yield of ‘Xundan 996’ were 10431.8 kg/hm2 and 9904.5 kg/hm2, increasing by 3.6% and 4.6% compared with the control‘Zhengdan 958’, respectively. In the 2-year regional test, the coefficient of variation of yield was 16.73% and 12.91%, both lower than the control. The high stability coefficients were 78.29% and 82.21%, respectively, which were both higher than the control. The regression coefficients were 0.9440 and 0.9398, which were both less than 1 and lower than that of the control. The yield increase rates were 64.1% and 82.1%, respectively. Meanwhile, the trial results indicate that ‘Xundan 996’ has good lodging resistance, disease resistance, and high temperature tolerance. Comprehensive analysis shows that ‘Xundan 996’ is a new maize variety with high and stable yield, wide adaptability, and strong stress resistance, which is suitable for large area planting in the summer maize area of Huang-Huai-Hai.
