Yield Component Interactions in Cultivars of the Highbush Blueberry

James H. Siefker, James F. Hancock

Abstract

Abstract Yield component analysis of 9 Vaccinium corymbosum L. blueberry cultivars indicated that yield was more strongly determined by canes per bush and berries per cane than by berry weight. High numbers of berries per cane were associated with low berry weights in all cultivars. Component interactions ranged from slightly additive in ‘Bluecrop’ and ‘Spartan’ to highly compensatory in ‘Rubel’ and ‘Berkeley’. The consideration of component interactions in cultivar trials may enhance the accuracy in identification of desirable genotypes.
