Production of F1 hybrid cotton seed depends on either honeybee or bumblebee spred of the pollen from male rows to female rows. It is recognized that bumblebees are the most effective pollinators. Given the indigenous populations of the bumblebee in the east and the lack of destructive insects until late in the season it was reasoned that North Carolina may be an ideal location for the production of hybrid seed. Hybrid seed was produced at two locations in 1990 and 1991. Seedcotton yields on the female rows were equal to that of the male rows at two environments, two thirds as productive at one environment, and half as productive at the fourth environment. Given adequate male and female nicking and late season insect control, one could efficiently produce F1 hybrid seed in North Carolina.
