In popcorn vield was found to be positively associated with leaf breadth and node number whereas leaf length showed negative relationship. The multiple correlation co- efficient suggested that number of rows / ear was the most important yield component In sweet corn, node number was positively and significantly correlated with grain yield ear length, number of rows / ear and grain number/row accounted for 64.71 per cent whereas number of rows/ear and ear length contributed 54.48 per cent of variability in yield. Correlation coefficients among yield components were different in sweet and popcorn. This points to the need of development of different selection procedures for these two types of corn.
