新疆大麦品种(系)不同生态区适应性鉴定试验

Assessment of the Adaptability of Barley Varieties(Lines) to Different Ecological Zones in Xinjiang

本研究以10个大麦品种(系)为试验材料,在新疆不同生态区进行适应性鉴定试验,对各品种(系)在农艺性状、抗逆性、产量构成及产量等方面进行比较。结果表明,奇引6号的产量最高,达413.71 kg/667 m^(2);奇引2号、奇引9号、奇引5号和奇引3号的产量分别为393.21、390.64、387.26、377.83 kg/667 m^(2),分别比对照甘啤4号增产14.76%、14.01%、13.02%、10.27%,增产达到极显著水平;奇引7号、奇引4号的产量分别为359.94、349.00 kg/667 m^(2),分别比对照甘啤4号增产5.05%、1.86%,增产不显著。

In this study, 10 barley varieties(lines) were assessed for their adaptability to different ecological zones of Xinjiang and their agronomic characters including stress tolerance, yield composition, yielding ability, and yield stability. As a result, the barley variety Qiyin No.6 attained the highest yield of 413.71 kg/667 m^(2), 20.74% higher than the yield of the control variety Ganpi No.4;the varieties Qiyin No.2, Qiyin No.9, Qiyin No.5, and Qiyin No.3 attained the yields of 393.21, 390.64, 387.26, and 377.83 kg/667 m^(2), respectively,increasing by 14.76%, 14.01%, 13.02%, and 10.27%, respectively, compared with that of the control. Furthermore, the varieties Qiyin No.7 and Qiyin No.4 showed the yields of 359.94 and 349.00 kg/667 m^(2), respectively, which were 5.05% and 1.86%, respectively,higher than that of Ganpi No.4, but the yield increases were not significant.
