将216份大麦材料(引自中东5个不同生态地区的5个野生大麦自然群体和其相应地区的5个农家种大麦群体)分2a种植在陕西关中地区,对其9个主要农艺性状进行分析。结果表明,大麦群体间分别在株高、穗长、芒长、穗下节长、旗叶宽、旗叶长、穗粒数、分蘖数等农艺性状上存在显著差异,大麦群体间总体表现出丰富的遗传多样性,野生大麦群体间多样性高于农家种。3个地区的大麦农艺性状差异更加显著;野生大麦群体间多样性高于其群体内,而农家种大麦群体间多样性低于其群体内。试验材料的农艺性状和来源地生态地理环境关联分析表明,部分性状可以和生态地理环境相关联,主要是和作物产量相关的农艺性状与温度、降水量及海拔等因素相关联;与农家种大麦相比,野生大麦与生态地理环境的关联更为密切。
Two hundred and twenty-two barley material (five wild barley populations from five different ecoregions in the Middle East and five farmers in their respective regions) were planted in the Guanzhong area of Shaanxi Province for analysis of nine major agronomic traits . The results showed that there were significant differences in the agronomic traits among the population of barley such as plant height, spike length, mantle length, ear length, flag leaf width, flag leaf length, spike grain number and tiller number. Rich genetic diversity, the diversity of wild barley among the groups is higher than that of the farmers. The differences of agronomic traits among the three regions were more significant. The diversity among wild populations of barley was higher than that of wild populations. However, the diversity among farmers was lower than that of other populations. The analysis of the agronomic traits of the tested materials and the eco-geographical environment of the provenances showed that some traits could be associated with the eco-geographical environment, mainly related to the factors such as temperature, precipitation and altitude, and other agronomic traits related to crop yield. In contrast, wild barley is more closely linked to the eco-geographical environment.
