To understand the association of various quality traits among themselves. Selected maintainers and restorers were analyzed for various grain quality and physico-chemical characters in order. Hulling percentage showed positive significant correlation with milling percentage and head rice recovery indicating that the genotypes with higher hulling percentage also recorded higher estimates for milled rice and head rice. Head rice recovery also showed negative but non-significant correlation with grain L/B ratio. Negative significant association of kernel length with kernel breadth indicates that grain length and slenderness are inherited independently resulting in long slender grain types. Positive significant correlation between kernel length and water uptake indicates that genotypes with longer kernels showed enhanced water absorption. Correlation of amylase content with volume expansion ratio, alkali spreading value and gel consistency was positive but nonsignificant.
