Description
Text
Hybrid - refers to the first generation of the cross that involves two or more inbred lines. Inbred lines are developed by controlled self-pollination of adapted strains for 4 to 5 generations. Hybrid corn varieties are the result of a repeated process of self-pollination of corn varieties of the same kind, called inbred lines. Different inbred lines are then crossed to produce hybrids. Hybrid varieties tend to have extended vigor and produced higher yield.
Modern Open Pollinated Varieties (OPV) - refers to corn seed materials which are grown for a longer period of time and maintained by natural cross pollination from generation to generation. These are purebred strains with seed that can be saved and planted from year to year. Open pollinated varieties will bred true if they are isolated from other varieties, avoiding cross-pollination. They are usually distinguished by their kernel color, kernel shape and other agronomic characteristics.
Native OPV - refers to the indigenous varieties. If the response is code 3, Go to Column 32.
