几个藜麦品种在凉山州的产量稳定性及适应性分析

Analyses on Yield Stability and Adaptability of Several Quinoa Varieties in Liangshan Prefecture

以凉山州藜麦品种多点试验数据为基础,采用Finlay和Wilkinson模型及品种与地区互作效应估算,分析了Blanca(v1)、Black pixankalla(v2)、Pasankalla(v3)、西选17-8(v4),陇藜1号(v5)、陇藜2号(v6)、陇藜3号(v7)、青藜1号(v8)等8个藜麦品种的在凉山州的丰产稳定性和适应性。结果表明,不同品种在不同地区的产量表现存在着极显著差异,v4为高产较稳定型品种,在不同的试验场点均表现出较好的丰产性,具有较好适应性,v1、v5为高产不稳定型品种,在适宜的地区产量表现较好,具有特殊的适应性,v8、v2、v6为较高产稳定型品种,产量尚可,但具有较广泛的适应性;v7、v3为低产稳定型品种,不适宜该地区种植。

Based on data from multi-site tests in Liangshan prefecture,using Finlay and Wilkinson models and estimating interactive effects between varieties and test sites,we analyzed the yield stability and adaptability of eight varieties of quinoa,i.e.,Blanca(ν1),Black pixankalla(ν2),Pasankalla(ν3),Xixuan 17-8(ν4),Long quinoa 1(ν5),Long quinoa 2(ν6),Long quinoa 3(ν7),and Qing quinoa 1(ν8)in Liangshan prefecture.The results showed that the yield performance of different varieties differed significantly in different test sites.Theν4 was a high-yield and stable variety,which showed good yield and adaptability in different test sites.Theν1 andν5 were high-yield and unstable varieties,which showed good yield performance and special adaptability in suitable environments.The v8,v2 and v6 were high-yield and stable varieties with modest yields but have a wider range of adaptability.The low-yield and stable varieties of v7 and v3 are not suitable for planting in Liangshan region.
