Correlation studies made with nineteen diverse genotypes of baby corn (Zea mays L.) for seven nutritional quality parameters, viz., sugar, protein, potassium, ascorbic acid, phosphorus, iron and calcium contents revealed the positive association of protein content with ascorbic acid, sugar and calcium and negative with potassium and phosphorus. Ascorbic acid got a positive correlation with all the quality parameters under experiment except iron. Calcium showed a negative trend with sugar, phosphorous and potassium and positive with remaining parameters. There existed a positive and highly significant correlation between phosphorous and potassium. Iron content showed a positive correlation with potassium and calcium and negative with other parameters. This suggests that breeding for high protein content will lead to simultaneous improvement in ascorbic acid, sugar, and calcium. Similarly, selection for high iron content will simultaneously enhance potassium and calcium.

婴儿玉米营养品质参数之间的相关性研究

与19种不同基因型婴儿玉米（玉米）的相关性研究。L.）就七个营养质量参数而言，即糖，蛋白质，钾，抗坏血酸，磷，铁和钙的含量显示蛋白质含量与抗坏血酸，糖和钙呈正相关，而与钾和磷呈负相关。除铁外，抗坏血酸与所有质量参数呈正相关。钙与糖，磷和钾呈负趋势，其余参数呈正趋势。磷和钾之间存在正相关且高度显着相关。铁含量与钾和钙呈正相关，与其他参数呈负相关。这表明高蛋白含量的育种将导致抗坏血酸，糖和钙的同时改善。同样，
