Abstract

White- and yellow-endosperm popcorn synthetics made up of standard popcorn inbreds from the United States were studied mainly to determine their possible utilization as sources of germplasm for high popping expansion. Among the 9 white-edosperm synthetics, Synthetic white Pop nos. 9, 3, and 2, had the highest popping expansion with values of 26.75, 24, 58, and 22, 51, respectively, as against that of the check, Laguna White Pop. Which was 18.70. Synthetic White Pop 2, though the lowest among the three in popping expansion, is also desirable as source of good germplasm for high popping expansion for it had also higher yield and better relative resistance to stalk breaking and Helminthosporium leaf spot than the other two synthetics. Its only outstanding liability is the poor husk coverage on the ears. Among the 19 yellow-endosperm synthetics, Synthetic yellow Pop nos., 12, 3, 8, 7, 2, and 13, (in the order of their decreasing popping expansion) gave both high popping expansion and relatively good yields. Synthetic Yellow Pop nos. 12 and 13 gave popping expansion of 27.45 and 20.32, respectively, as against that of the check, Davao Yellow Pop, which was 14, 32. In the dry season. If recommendations were to be made, these six synthetics, would probably be selected as follows; 3, 12 8, 7, 2 and 13, in the order of their predicted usefulness as source of germplasm for high popping expansion, Fairly good yield, and relative resiatnce to stalk breaking and Helminthosporium leaf spot.
