摘要
Starch viscosity is closely associated with noodle quality. RVA(rapid viscosity analyzer) was used to investigate the paste property of leading Chinese wheat varieties arid 38 Australian wheat lines. Results showed that significant variability for RVA parameters was observed among Chinese wheat varieties, particularly among spring wheat varieties. In general, Australia wheat lines performed better paste characters than that of Chinese winter wheats. Genotype (G), environment (E) and genotype by environment (G×E) interaction affected all paste traits. Correlation analysis indicated that peak viscosity correlated highly and significantly with viscosity, breakdown, setback, final viscosity, peak time, and falling number(r = 0.56-0.93, P<0.01). However breakdown was not significantly associated with most paste properties. Paste characters increased from low to high latitude both in the north and south part of Yellow and Huai Valley.
