AbstractConicalness is estimated in maiz Zea mays L.) by the slope of the ear edge. The trait was measured in random samples of ten ears from 73 local populations from Galicia (northwestem Spain) grown at two Iocations for two years in experiments arranged in randomised complete blocks. The coefficients of correlation of conicalness with 19 other plant and ear traits were in general small. Conicalness showed high values of broad-sense heritability (0.77) and constancy (2.46). It is suggested that the trait should be considered in numerical classifications of local populations of maize.
