Abstract: To develop and utilize waxy corn pigment,Xixinghuangnuo 6,Xixingchinuo 1,Zinuo 208 and Xixingheinuo 1 were used to determine the changes of carotenoid and anthocyanin contents during kernel development and the contents of nutritional substances in kernel maturity.The correlations between pigment content and nutritional character were analyzed.The results indicated that the contents of carotenoid and anthocyanin showed a single peak curve with kernel development.In maturity,anthocyanin and pigment contents appeared Xixingheinuo 1 >Zinuo 208> Xixingchinuo 1 >Xixinghuangnuo 6,The order of carotenoid content was just the opposite.Correlation analysis showed that anthocyanin and pigment contents were positively correlated to crude starch,fat,glucose and sucrose contents,and negatively correlated to crude protein and soluble protein contents.The correlation between carotenoid and nutritional substances was just the opposite.Therefore,the darker kernel color was,the higher contents of pigment and anthocyanin,the lower content of carotenoid.There existed a very close relationship between kernel pigment and nutritional character of waxy corn.

Key words: Waxy corn, Pigment, Anthocyanins, Carotenoids, Nutritional character
