小麦新品种平安0602高产稳产性分析

Analysis of the high and stable yield of new wheat variety Ping′an 0602

为了揭示小麦新品种平安0602在不同生态区域高产稳产特性,依据2015—2017年河南省冬小麦区域试验产量汇总资料,采用产量、变异系数、高稳系数、回归系数及坐标法对试验数据进行分析。结果表明:平安0602两年度的产量分别较对照品种增产7.04%和4.83%,表现出高产特性;两年度的回归系数值分别为1.0565和1.0199,接近群体回归系数值1.000,表现出稳产特性;高稳系数值均低于对照品种;回归线均在群体平均线以上。以上参数说明小麦新品种平安0602具有高产稳产的特性,且该品种在审定区域内有较高的推广价值。

This study aims to explore the characteristics of the high and stable yield of new wheat variety Ping′an 0602 in different ecological regions.According to the results of Henan Province regional test in 2015—2017,the data were analyzed by yield,variable coefficient,high-stable yield coefficient,regression coefficient and coordinate method.The result showed that the yield of Ping′an 0602 was higher than that of the control variety by 7.04%and 4.83%in two years.Ping′an 0602 showed the characteristic of high yield.The regression coefficient at 1.0565 and 1.0199 was close to that of population 1.000.Ping′an 0602 showed the characteristic of stable yield.The value of high stability coefficient was lower than that of the control variety and the regression line was above that of population,both suggesting high and stable yield.Ping′an 0602 has a high extension value in the examination area.
