Abstract
The purpose of this experiment was to determine the value of isolation and male border rows in reducing contamination from foreign pollen in hybrid seed corn production. The study was made at two field stations near Lincoln, Nebraska in 1948. One planting was made with the male rows adjoining the contaminating field, the other with an isolation area between the contaminating field and the male border rows. The male border rows and the rows representing the female parent of a seed field were planted with a white hybrid corn. The contaminating fields were of yellow hybrid varieties. The rows representing the female parent were detasseled before they shed pollen. Crosses were determined by the xenia effect. The highest per cent of seed set occurred close to the pollen source and decreased as the isolation distance increased. Advisor: F. D. Keim.
