Foliar C isotope discrimination (Δ) and yield of green coffee (Coffea arabica L.) beans were evaluated for seedling populations from 14 diverse coffee cultivars growing in Hawaii. A was negatively correlated with yield of green coffee beans. The 2% variation in A observed in leaves sampled about 2 months after completion of the first harvest corresponded to a 3-fold variation in yield. Substantial variation in A exists among coffee cultivars, and foliar A analyses show promise as a means of selecting superior genotypes of long-lived woody crops.
