摘　　要：通过对引自黑龙江、四川和河南等地的13份大麦品种材料进行试种,观察这些大麦在黔中地区自然生态条件下和盆栽条件下的生长发育特性和农艺性状表现。结果显示,所有参试品种材料都能完成生长发育的各个阶段,在大麦物候期和主要农艺性状上,不同品种材料间存在着明显的差异,方差分析均达极显著水平(p<0.000 1)。在供试大麦的产量构成上,13份材料中其千粒重超过50 g的有一半以上,仅3份材料的千粒重不足45 g。同时,播期、栽培方式和环境条件等对引种大麦生长的影响极显著,物候期与农艺性状以及农艺性状间存在显著斯皮尔曼秩相关性。综合分析表明,在黔中生态气候条件下,13份省外大麦品种材料均能正常生长,且具有良好的生态适应性,从而为进一步筛选出综合性状优良的大麦品种,培育能适应在贵州种植的大麦新品种提供依据。Thirteen barley cultivars introduced from Heilongjiang,Sichuan and Henan provinces were grown under the natural and potted coonditoins in the Center of Guizhou province（Huaxi in Guiyang）,followed by the investigation of the phenological and agronomic characteristics,as well as the relationship among these characters under the local conditions.The results showed that 13 barley cultivars displayed a normal growth in the center of Guizhou.ANOVA indicated that there were significant differences on the phenological and growth characteristics among 13 barley cultivars.1000-kernel weight of more than half of all barley cultivars was over 50 gram,and only three cultivars had lower than 45 gram.Some factors,i.e.seedtime,cultivation pattern and environmental condition,affected the growth of the barley varieties.Spearman＇s Rho Correlation analysis showed significant correlations among the phenological and phenotypic characteristics.Most barley cultivars demonstrated a good adaptability in the present study.The obtained results provide the valuable information for choosing and breeding new barley varieties which will be grown exclusively in the central area of Guizhou province.
