There was no significant difference between yields of this new hybrid and the commercial variety i.e. Hibrix 3 which gave 2,589 and 1,898 kg/rai (ca. 414.24 and 303.68 kg/ha) for the corn with and without husk, respectively. Percentage of kernel of Chai Nat 86-1 variety was 40% whereas Hibrix 3 was 31%. Sweetness of Chai Nat 86-1 and Hibrix 3 corns was not different. Average ear size of the new variety was 5 x 18 cm with cylindrical shape. The new corn could be grown well in irrigation and rainfed area before and after paddy rice production season.
