【摘要】 选用我国黄淮麦区141份主要小麦品种(系),探讨了它们的糊化特性遗传变异及其它主要品质的相关分析。结果表明:我国黄淮小麦品种糊化特性表现出较大的变异,峰值粘度、低谷粘度和衰减度等性状的变异范围分别为1196-4241cp、409-2834cp、548-1680cp,15份材料的峰值粘度、衰减度分别超过3000cp和1300cp。说明通过遗传改良我国小麦糊化特性潜力是很大的。淀粉膨胀势与糊化特性的大多数指标均达到极显著相关,在早代单株选择时,用膨胀势代替糊化测定是可行的。更多还原

【Abstract】 In this paper,141 wheat cultivars and advanced lines from Yellow and Huai wheat valleys were used to study the paste traits variation and their relationship with other quality traits.The results showed that significant variations were observed in most of paste traits of these wheat cultivars.The variation range of peak viscosity,hold through and break down was 11964241cp,409-2834cp,548-1680cp,respectively.There were fifteen wheat cultivars peak viscosity up to 3000cp and breakdown up to 1300cp,respectively.So,potentiality of improving Chinese wheat paste traits was very big.The correlations among flour swelling power and most paste traits were significant,so that swelling power was feasible of paste traits in early generation of selecting cultivar.更多还原
