A COMPARISON OF FRUIT YIELDS OF LOWBUSH BLUEBERRY CLONAL LINES AND RELATED SEEDLING PROGENIES

Abstract

Up to 39 tonnes/ha were obtained in three-harvest cumulative yields of superior lowbush blueberry materials planted in 1972 and harvested in 1974, 1976 and in 1978. Plants from four select clones yielded an average of 50% more fruit than did their four respective seedling progenies. At a spacing of 20 000 plants/ha, 70% survived through the third fruiting season.
