Performance of intervarietal crosses of maize and sweet corn and correlations among agronomic characters

Four open-pollinated varieties of maize and sweet corn, Guatemala, Chinta, Hawaiian Sugar and Hawaiian Supersweet 4 were crossed in all possible combinations and evaluated in the field in 1972. Among the 13 characters studied, days to flowering, Helminthosporium score, plant height, ear height, ear...
