摘　　要：为了研究不同麦区小麦(Triticum aestivum L.)种质资源在以襄阳市为代表的鄂北岗地品质表现及农艺性状变异情况,对226份小麦品种进行了农艺性状分析和品质指标测定,并对每穗粒数、千粒重、株高等5个农艺性状指标和包括蛋白质含量、湿筋含量、沉淀值等在内的11个品质指标相关数据进行了变异、相关性分析。结果表明,在鄂北岗地,不同品种的每穗粒数差异最大,千粒重、小穗数的差异较小,品质指标中容重变异最小,稳定时间变异最大。相关性分析结果表明,多个农艺、品质性状间存在显著相关性,在小麦育种及种质资源创新中要兼顾考虑,用于提高优质小麦的选择效率和综合评价的准确性。The performance and variation of wheat(Triticum aestivum L.)quality and agronomic characters on wheat germplasm of dif⁃ferent types planted in humpy ground in Xiangyang of northern Hubei province were studied.We have analyzed the agronomic charac⁃ters and quality indices.The variation analysis and correlation analysis were made on five agronomic character indices including grain number per spike,1000-grain weight,plant height and 11 wheat quality indices such as protein content,wet gluten content and sedi⁃mentation value.The results of variation analysis showed that the grain number per spike had the highest variation,while the least vari⁃ation was found on 1000-grain weight and spikelet number.As for quality indices,the bulk density was with the smallest variation while stability time had the highest variation.Correlation analysis showed that significant positive correlations among the agronomic characters and quality indices.It should be considered in wheat breeding and germplasm resources innovation to improve the selection efficiency of high quality wheat and the accuracy of comprehensive evaluation.
