苦荞新品种丰产稳产性分析

Analysis on Steady and High Yield Ability of New Tartary Buckwheat Varieties

根据2019—2020年山西省苦荞品种自主联合区域试验数据,采用方差分析、Duncan′s新复极差测验法及高稳系数法对各参试品种进行丰产稳产性分析。结果表明:粱苦荞1号、右苦荞1号、同苦荞1号和品苦荞1号平均产量分别为1921、1865、1851、1804 kg/hm^(2),分别较对照晋荞麦(苦)6号增产16.7%、13.3%、12.5%、9.6%,差异显著,但这4个品种间产量差异不显著;高稳系数分别为24.83%、27.92%、26.49%、31.85%,均小于对照晋荞麦(苦)6号的35.60%。说明这4个品种均比对照高产稳产,在山西省苦荞产业发展中具有良好的应用前景。

According to the data of independent joint regional test of tartary buckwheat varieties in Shanxi Province from 2019 to 2020,the steady and high yield ability of the tested varieties were analyzed by using variance analysis,Duncan′s new multiple range test and high-stability coefficient method.The results showed that the average yields of Liangkuqiao 1,Youkuqiao 1,Tongkuqiao 1 and Pinkuqiao 1 were 1921 kg/hm^(2),1865 kg/hm^(2),1851 kg/hm^(2)and 1804 kg/hm^(2)respectively,which were 16.7%,13.3%,12.5%and 9.6%higher than that of the control Jinqiaomai(ku)6,and the difference reached a significant level,but the yield differences among the four varieties were not significant.The high-stability coefficients were 24.83%,27.92%,26.49%and 31.85%respectively,which were less than 35.60%of the control Jinqiaomai(ku)6.It indicated that compared with the control,these four varieties had higher and stabler yield,and had a good application prospect in tartary buckwheat industry development in Shanxi Province.
