不同基因型和环境影响小麦主要品质的研究

选用参加山东省2005~2006年小麦高肥组区域试验的11个小麦品种(系),研究了不同品种(系)的硬度、容重、粗脂肪含量、蛋白质含量、沉淀值、湿面筋含量、粗淀粉含量、黏度、稳定时间、W值、P/L值和小麦粉白度等小麦主要品质性状在9个地区不同生态环境条件下的遗传变异。结果表明,所有性状均受基因型、环境及其互作的影响,且影响排序为基因型(环境(两者互作(除容重外);所有品种的绝大多数性状表现出显著的差异(P0.05);所有地区的绝大多数性状表现出显著的差异(P0.05);不同品种在不同地区的稳定性不同,DH5197的稳定性较好、泰山098的稳定性较差。

Effects of Different Genotype and Environment on Quality Traits of Wheat

11 wheat varieties selected from the test materials for a high-fertilizer regional trial in 2005~2006 in Shandong Province were used to study the genetic variations of wheat grain hardness,unit weight,crude fat,protein,sedimentation value,wet gluten,crude starch,peak viscosity,stability time,W value,P/L value,and flour whiteness in 9 different ecological environments.Results:All the test traits are affected by genotype,environment and their interaction;and the impact of genotype is greater than that of envi...
