玉米品种漯玉16丰产性、稳产性、适应性及抗逆性分析
Analysis of high yield,yield stability,adaptability and stress resistance of maize variety Luoyu 16
摘要
Abstract
Luoyu 16 is a maize variety developed through pedigree selection,using the inbred line Luo 7007 as the female parent and the introduced line Changgai 3 as the male parent.It was approved by the National Crop Variety Approval Committee in 2019(Guoshenyu 20190309).Based on data from the Huang-Huai-Hai summer maize regional trials(2017-2018)and production trials(2018)conducted by the Henan Agricultural Consortium,this study analyzed the high yield,yield stability,adaptability,and stress resistance of Luoyu 16 using indicators such as coefficient of variation,high-stability coefficient and adaptability index.The results showed that during the period 2017-2018 regional trials and production trials,the yield of Luoyu 16 ranged from 9 456.0 to 10 287.0 kg/hm²,representing a 7.7%-8.3%increase compared to the CK,Zhengdan 958,with an average yield increase rate of 89.8%.The coefficient of variation ranged from 13.7%to 16.3%,the high-stability coefficient ranged from 82.0%to 85.0%,and the adaptability index ranged from 48.6%to 60.0%.The ratio of ear height to plant height was 0.409,the average lodging and breaking rate was 2.1%,and the variety exhibited moderate resistance to stalk rot,ear rot,and southern leaf blight.In conclusion,the maize variety Luoyu 16 demonstrates favorable high yield,yield stability,adaptability,and stress tolerance,indicating high potential for promotion and utilization.关键词
