Yield and Quality Attributes of Rainfed Green Immature Corn in Trinidad

in HortTechnology

Three local varietal types of corn (Zea mays L.)—an improved landrace `ICTA Farm Corn' derived from the Tuson population, the open-pollinated `Across 7728', and the hybrid `Pioneer 3098'—were grown at three cash-crop farms in Trinidad, and evaluated as green corn for agronomic, quality, and chemical traits. `Pioneer 3098' and `ICTA Farm Corn' had similar numbers of marketable ears and marketable yield per hectare, and both were superior to `Across 7728'. Sensory evaluations revealed that the three varieties did not differ in overall quality when boiled with Creole seasoning. When ears were not seasoned, the hybrid variety was preferred over the two open-pollinated varieties. Two-dimensional partitioning indicated that ear appearance and kernel color were the major contributors to total variation in overall quality. The importance of quality characters of green corn to local farming system priorities affects extension recommendations and breeding objectives in Trinidad.
