摘要
对玉米品种的丰产性和稳产性进行综合评价,可以为品种在适宜区域的推广种植提供理论依据。基于2019~2020年国家黄淮海夏玉米组品种区域试验和2020年国家黄淮海夏玉米组品种生产试验的产量数据,以郑单958为对照品种,利用平均值法、变异系数法和高稳系数法,对石家庄市农林科学研究院和河北德丰种业有限公司共同选育的国审玉米新品种德丰C919(石玉1502)进行了丰产性和稳产性分析。结果表明:2019~2020年国家黄淮海夏玉米组品种区域试验和2020年国家黄淮海夏玉米组品种生产试验,德丰C919(石玉1502)平均产量分别为10542.0、10414.5和10497.0 kg/hm^(2),分别居同组参试品种第3位、第1位和第1位,较CK增产6.3%、9.7%和6.7%,差异均达到了极显著水平;产量变异系数分别为14.59%、14.44%和15.28%,分别居同组参试品种第11位、第2位和第4位;高稳系数分别为82.55%、85.35%和82.17%,分别居同组参试品种第7位、第1位和第4位。综合分析认为,德丰C919(石玉1502)丰产性和稳产性均表现较好,是一个产量稳定、适应性强且增产潜力巨大的玉米优良品种,适宜在黄淮海夏播玉米区大面积推广种植。
The comprehensive evaluation of the high and stable yield of maize varieties can provide a theoretical basis for the popularization of varieties in suitable regions.Based on the yield data of the national regional tests of Huang-Huai-Hai summer maize group varieties from 2019 to 2020 and the national production test of Huang-Huai-Hai summer maize group varieties in 2020,with Zhengdan 958 as the control variety,using the average value method,variation coefficient method and high stability coefficient method,the yield and stability of the national approved new maize variety Defeng C919(Shiyu 1502)jointly bred by Shijiazhuang Academy of Agriculture and Forestry Sciences and Hebei Defeng Seed Industry Co.,Ltd.were analyzed.The results showed that the average yield of Defeng C919(Shiyu 1502)was 10542.0 kg/hm^(2),10414.5 kg/hm^(2) and 10497.0 kg/hm^(2) respectively in the regional tests of national Huang-Huai-Hai summer maize group varieties from 2019 to 2020 and production test in 2020,which ranked the 3rd,1st and 1st in the group,and increased by 6.3%,9.7%and 6.7%,respectively than CK and the different reached a very significant level.The yield variation coefficients were 14.59%,14.44%and 15.28%,respectively,ranking 11th,2nd and 4th in the group.The high stability coefficients were 82.55%,85.35%and 82.17%,respectively,ranking 7th,1st and 4th among the tested varieties in the group.According to comprehensive analysis,Defeng C919(Shiyu 1502)has outstanding performance in high yield and stable yield,and is an excellent maize variety with stable yield,strong adaptability and huge potential for increasing yield,which is suitable for large-scale promotion and planting in Huang-Huai-Hai summer sowing maize area.
