摘要
对引自我国主要大麦种植区9份啤酒大麦品种在黔中的生育期、主要农艺性状、抗倒伏性、抗病性等进行了观察分析。结果显示:参试的9份大麦品种均能正常生长,但其生育期、各主要农艺性状等表现型均存在明显的差异;在产量构成中,千粒重大于42克以上的啤酒大麦材料有6份,且所有参试材料的穗粒数均有增加的趋势;物候期与农艺性状,以及农艺性状相互间存在显著的斯皮尔曼秩相关性。综合分析表明:云啤2号、浙秀12、鄂32380、扬农啤5号、苏啤4号和盐城01094等6份啤酒大麦品种能适应黔中地区的生态气候条件,这些良好的生态适应性及物候性状的差异,可为进一步筛选出适宜在黔不同生态区种植啤酒大麦的优异农艺性状提供依据。
The growth period, main agronomic characters, lodging resistance and disease resistance of nine beer barley varieties introduced from five provinces in China were determined in Guiyang city to provide the scientific basis for selecting varieties with good agronomic and different ecological characters in Guizhou. The results showed that there was obvious difference in growth period and different main agronomic characters among tested varieties, 1000-grain weight of six tested varieties was over 42g and grain number per ear of all tested varieties showed the increase trend compared with that of varieties grown in their original regions, and there was a significant Spearman＇ s Rho correlation between phonological phase and agronomic characters, and between different agronomic characters. The comprehensive analysis indicated that yunpi 2,Zhexiu 12, E 32380, Yangnongpi 5 and Yancheng 01094 could be adapted to the ecological and climatic condition of the central region of Guizhou province.
