摘　　要：在江苏省 6个小麦生态区 ,选用大面积推广的 7个不同品质类型的专用小麦品种 ,研究了小麦籽粒品质性状的生态变异特点。结果表明 :除籽粒淀粉含量不受环境主效应的影响外 ,其余各品质性状均受基因型和环境主效应以及二者互作效应的显著影响 ;籽粒蛋白质含量和面粉降落值受基因型和环境主效应的影响相近 ,而其余品质指标的基因型主效应明显大于环境效应。表明在江苏省优质小麦生产中 ,品质的遗传改良和深入的品质生态区划非常重要。不同品种在各生态点品质性状的表现趋势不同 ,可能导致品质区划结果不同 。Seven typical specialty winter wheat cultivars were sown at six representative ecological sites in Jiangsu Province to investigate the variation in grain quality traits of different cultivars under different environments.All wheat quality traits were significantly affected by the main effects of genotype and environment,and the interactive effects between genotype and environment,except that grain starch content was not affected by the environment.The main effects of genotype on grain protein content and flour falling number were similar to those of environment,but were greater on the other quality traits than those of environment.It was indicated that both genetic improvement and intensive eco zoning in grain quality were of importance for production of superior specialty wheats in Jiangsu Province.Also,different performances of grain quality traits were not unique at different environments.The eco zoning conclusion could subsequently differ,which should be carefully considered during quality eco zoning in wheat.
