摘要
文章对1985年-2020年河南省通过审定的125个大豆品种的产量变化进行统计,并做了回归分析。结果表明,已审定大豆品种区域试验和生产试验产量与审定年份之间表现显著的线性回归关系,产量总体呈上升趋势;1985年-2015年区域试验最高产量逐渐增加,2016年-2020年相比2010年-2015年区域试验最高产量略有下降;审定品种区域试验和生产试验平均产量最高值与最低值相比,分别增长39.19%和58.51%。
This paper makes statistics and regression analysis on the yield changes of 125 soybean varieties approved in Henan Prov‐ince from 1985 to 2020.The results showed that there was a significant linear regression relationship between the yield of approved soybean varieties in regional test and production test and the approved year,and the yield showed an upward trend as a whole.From 1985 to 2015,the maximum output of regional test increased gradually,and from 2016 to 2020,the maximum output of regional test decreased slightly compared with that from 2010 to 2015.Compared with the lowest value,the highest value of average yield in re‐gional test and production test of approved varieties increased by 39.19%and 58.51%respectively.
