Natural Variability in Yield of Lowbush Blueberries

Abstract

One hundred lowbush blueberry (Vaccinium angustifolium Ait.) clones were randomly sampled from a commercial field to estimate potential productivity. Yield data exhibited a normal distribution ranging from 300 to 17,000 kg·ha -1 with a mean of 7726 kg·ha -1 . Commercial use of selected clones or improved cultivars through new plantings, interplanting into existing clones, or replacement of low-yielding clones in native stands and increasing the intensity of field management would increase the yielding potential of native lowbush blueberry fields.
