Inflence of diverse pollen source on fruitfulness of apple

Abstract

Red Fuji with Red Gold, Mollies Delicious, Oregon Spur, and Silver Spur with Red Gold resulted high fruit set per cent. Golden Delicious with the entire pollen source resulted in good to fair fruit set further, Golden Delicious with Silver Spur and Oregon Spur resulted in above 90-97% fruit set. Coe red Fuji with Red Gold, Oregon Spur, Mollies Delicious recorded very high fruit set whereas with Vista Bella, Silver Spur, Starkrimson and Top red resulted in good fruit set. Prima with Golden Delicious and Granny Smith resulted in very high fruit set, whereas Oregon Spur with Golden Delicious or Maharaji showed high compatibility.Therefore, the information obtained on compatibility studies in apple will be useful in planning breeding strategies, controlled hybridizations and orchard design to ensure adequate pollination.
