Analysis of correlations and path effects for popping expansion in popcorn ( Zea mays var. everta Sturt.)

Correlation and path analysis involving 35 genotypes of popcorn (Zea mays var. everta Sturt.) indicated that degree of popping alone exhibited positive association with popping expansion. The path analysis revealed that cob weight showed very high positive direct effect on popping expansion followed by plant height, days to maturity and days to 50% silking. Characters namely degree of popping, lesser cob length, cob girth and 100- kernel weight could be given greater emphasis while making selections for the improvement of popping expansion.
