Correlation Between RVA Profile Characteristics and Main Quality Traits in Waxy Maize

Twenty-six waxy maize varieties were determined on RVA profile characteristics,the total starch con-tent,amylopectin content,amylose content and quality traits,and the relationship among RVA profile characteristics and between RVA profile characteristics and main traits were studied.The results showed that significantly positive correlations were observed among peak viscosity (PV),trough viscosity (TV),breakdown (BD) and final viscosity(FV).RVA profile characteristics had no significantly correlation with total starch content,amylopectin content,amylose content.Glutinousness and PV,TV,BD,FV was significantly negatively,Thickness of skin and PV,TV,FV showed significant negative correlation.
