Breadfruit. Artocarpus altilis (Parkinson) Fosberg. Promoting the conservation and use of underutilized and neglected crops.

1997.

ABSTRACT: Despite its widespread distribution and use, little work has been done on characterization, evaluation and description of breadfruit germplasm. This publication describes the genetic resources of breadfruit and provides an in-depth look at the current status of breadfruit conservation and the extent of ex situ germplasm collections, especially in the Pacific Islands. Chapters cover the following topics: taxonomy, botany, evolution and domestication, properties and uses, conservation and genetic diversity, breeding, production, ecology, agronomy, and limitations, prospects and research needs. Two appendices detail research contacts and research centres, both by country.

Chromosome Numbers and Pollen Stainability of Three Species of Pacific Island Breadfruit (Artocarpus, Moraceae)

Diane Ragone
American Journal of Botany 88(4):693-696
2001

ABSTRACT: Chromosome numbers were determined for 48 accessions of breadfruit (Artocarpus altilis, A. mariannensis, and A. camansi [Moraceae]) from 16 Pacific Island groups, Indonesia, and the Philippines. Artocarpus camansi and A. mariannensis exhibit counts of 2n = 56; 2n = 56 (diploidy) and 2n = 84 (triploidy) were observed for A. altilis. Most diploid cultivars of A. altilis were seeded, but two cultivars with reduced seed number were observed. Micronesian accessions included putative interspecific hybrids between A. altilis and A. mariannensis. The majority of these accessions were seedless diploids, but triploid putative hybrids were also observed. Pollen stainablility was shown to correlate with the degree of seediness.

KEY WORDS: Artocarpus altilis, Artocarpus camansi, Artocarpus mariannensis, breadfruit, chromosome number, pollen stainability, Moraceae, Pacific Islands.

Complex Origins of Breadfruit (Artocarpus altilis, Moraceae): Implications for Human Migrations in Oceania.

Nyree J.C. Zerega, Diane Ragone, and Timothy J. Motley
American Journal of Botany 91(5):760-766
2004

ABSTRACT: Breadfruit (Artocarpus altilis, Moraceae), a traditional starch crop in Oceania, has enjoyed legendary status ever since its role in the infamous mutiny aboard the H.M.S. Bounty in 1789, yet its origins remain unclear. Breadfruit?s closest relatives are A. camansi and A. mariannensis. DNA fingerprinting data (AFLP, amplified fragment length polymorphisms) from over 200 breadfruit cultivars, 30 A. camansi, and 24 A. mariannensis individuals were used to investigate the relationships among these species. Multivariate analyses and the identification of species-specific AFLP markers indicate at least two origins of breadfruit. Most Melanesian and Polynesian cultivars appear to have arisen over generations of vegetative propagation and selection from A. camansi. In contrast, most Micronesian breadfruit cultivars appear to be the result of hybridization between A. camansi-derived breadfruit and A. mariannensis. Because breadfruit depends on humans for dispersal, the data were compared to theories on the human colonization of Oceania. The results agree with the well-supported theory that humans settled Polynesia via Melanesia. Additionally, a long-distance migration from eastern Melanesia into Micronesia is supported.

KEY WORDS: Artocarpus altilis, Artocarpus camansi, Artocarpus mariannensis, amplified fragment length polymorphisms, breadfruit, human migration, Oceania, origin of domesticated plants.

Sensory Evaluation of Fruit Quality and Nutritional Composition of 20 Breadfruit (Artocarpus, Moraceae) Cultivars

Diane Ragone and Catherine G. Cavaletto
Economic Botany 60(4):335-346
2006

ABSTRACT: Twenty breadfruit cultivars growing in a field genebank at Kahanu Garden, National Tropical Botanical Garden, Hana, Maui, Hawaii, were evaluated for sensory attributes and nutrient composition. A taste panel scored eight flavor/aroma attributes, five textural attributes, and color. There were significant differences (P ≤ 0.01) in aroma, visual texture, flavor intensity, sweetness, starchiness, moistness, stringiness, firmness, and color. The greatest differences were in color and texture. Nutrient analyses showed significant differences (P ≤ 0.05) for energy, carbohydrates, ash, crude protein, potassium, magnesium, sodium, iron, copper, and zinc. Considering the versatility of breadfruit as a food, its ease of production, and its nutritional value, the numerous good quality flavorful cultivars should be more widely grown for sustainable agriculture and food security.

KEY WORDS: Artocarpus altilis, Artocarpus mariannensis, breadfruits, cultivars, Pacific Islands, Seychelle Islands, texture, flavor, tropical, proximates, nutritive value, vitamins, minerals, fiber, carotenoids.

Key Access and Utilization Descriptors for Breadfruit Genetic Resources.

This list consists of an initial set of characterization and evaluation descriptors for breadfruit utilization. These, together with passport data, will form the basis for the global accession level information system being developed by the Bioversity-led project, Global Information on Germplasm Accessions (GIGA). It will facilitate access to and utilization of breadfruit accessions held in genebanks. Additional descriptors may be added later if information becomes available.
