%Fruit seti. Variability in flowering time, fruit set and fruit quality? (concluded in2010/11 season)• Fruit set was 35% Simone, 37% Van and 38% Sweetheart, around 75% of which was setover a 4-day window, not increased by hand pollination.• Fruit from earlier bloom date was not of higher quality than later bloom date fruit, incontrast to some results from Washington State (where crop loads were much higher)35.030.025.020.015.010.05.00.030-Sep'Sweetheart' Distribution ofFruit/Total Fruit as % by Date0.2 0.3 1.4 4.9 18.52-Oct4-Oct28.76-Oct8.520.28-OctBloom Date5.7 5.7 2.9 2.2 0.7 0.2 0.110-Oct12-Oct14-Oct
