Abstract

HYBRID seed of monoecious cucurbits is costly because roguing staminate flowers from seed-parent lines and transferring pollen from male to female parents by hand is costly. The introduction of a new growth-regulating compound, ethrel (2-chloroethanephosphonic acid) (Am-chem Products, Inc., Ambler, Pennsylvania), offers promise in significantly reducing the labour necessary for production of hybrid cucurbit seed.
