Introduction. Breadfruit, Artocarpus spp., is a
staple crop with the potential to alleviate hunger and increase food security in tropical
regions. Guidelines and recommendations for cultivar selection and production practices
are now required for establishment of breadfruit in new areas. Materials and
methods. To respond to this need for spreading breadfruit, our study quantified
the growth, development, yield and seasonality of 24 breadfruit cultivars (26 trees)
established in Kauai, Hawaii, over a 7-year period from 2006–2012. Individual production
profiles were generated for each accessioned cultivar based on major agricultural factors.
Results. Across all cultivars of breadfruit ( A. altilis),
an average of 269 fruits per year was produced by each tree with an average fruit weight
of 1.2 kg. Based on the planting density of 50 trees×ha–1, this translates to an average
projected yield of 5.23 t×ha–1 after 7 years. Hybrids (A. altilis
× A. mariannensis) had a higher yield than breadfruit. The data of our article
support the previously proposed hypothesis for predicting breadfruit seasonality. On
average, the peak season occurred from July to November. Conclusions.
Ma’afala, the first widely available commercial cultivar, started to bear fruit within 22
to 23 months of planting. Other cultivars with potential for commercial production include
Toneno, White, Rotuma and Meinpadahk.
