- Abstract
Incorporation of sweetness into waxy background is a means to diversify waxy corn products. The best gene combinations and the consumer preference have not been well documented for waxy corn. The objectives of this study were to incorporate sweetness into waxy background and identify gene combinations that are suitable for commercial production using sensory blind test of evaluation panel. The genes su, sh2 and bt were incorporated into waxy background as both a single gene and combination of 2 sweet genes. The segregation ratio of one sweet gene would be 3:1 of waxy kernels to sweet kernels, and the segregation ratio of two-gene combination would be 9:7 of waxy kernels to sweet kernels. Four of 6 crosses with 2 gene combinations were sweeter than all crosses with single gene combination. Two crosses with 2 gene combinations and 101bt as a female parent were not sweeter than those with one sweet gene. The parents with su and sh2 can be used as male and female parents, but the parent with bt (101bt) can be used as male parent only. Waxy trait was negatively associated with sweetness and crispiness, whereas sweetness was positively associated with crispiness and overall liking, indicating that increases sweetness in waxy corn can increase consumer preference. Sensory blind test can be used for evaluation of eating quality in waxy corn. Implication for breeding is discussed.
