Abstract

Two yellow double cross corn hybrids were used in studying the value of complete detasseling in the production of hybrid seed corn. F₁ seed of each hybrid was diluted with various amounts of F₂ seed of the female seed parents involved.

As an average for the two hybrids used in this study, each 10 per cent increase of F₂ mixture was shown to affect a reduction in yield of 2.74 bushels per acre. The increasing percentage of maternal parent F₂ had no appreciable effect on ear dropping or stalk lodging, or maturity.
