Abstract

Under open pollination conditions, the highest fruit set was observed in Red Gold (76.33%) and the lowest in Anna (51.44 %). Cross-compatibility studies revealed that Red Gold as pollinizer gave the highest fruit set in Golden Delicious Reinders (84.09%), whereas Anna showed partial compatibility with Pinova (38.33%), Sunhari (41.66%) and Golden Delicious Reinders (43.33%). Anna used as male against female parents registered maximum fruit drop in Pinova (51.20%). The source of pollen also had positive and significant effects on the fruit's qualitative characteristics i.e. colour. From the present study, it is concluded that the varieties Red Gold and Gala Redlum were the best pollen sources and exhibited maximum compatibility with most of the varieties.
