“…The passport data to source locations is presented in Online Resource 1. Native species were collected from wild habitats with specimens conservation methods as described in Wongniam et al (2010) including recently reported species, Musa yunnanensis (SS&JS 235, Häkkinen and Hong 2007) and M. serpentina (SS&JS 246, Swangpol and Somana 2011) and introduced species, M. ornata (SS&JS 433), M. coccinea (SS&JS 223), and Musella lasiocarpa (SS&JS 231), were ornamental plants and maintained in institute or private collections. Cultivars samples and the given names called by the local growers were obtained from several banana distributors.…”

Bananas in Thailand have been surveyed by our team to be at least 140 cultivars in the plantations, 10 wild species and, 4 introduced species. To characterize the genetic relationship of species and cultivars, a set of novel SSR markers was developed. Totaling 53 clones containing SSR motifs were isolated from SSR-enriched library of wild Musa balbisiana Colla 'Tani' (BB). Selected positive clones were used to design 28 primer pairs for amplification of 12 wild and 82 cultivar accessions with genome designations AA, AB, AAA, AAB, ABB, and BBB. These SSR markers loci were homology searched to the banana genomes to map their locations. The seven-sets multiplex PCR approach using four fluorescent-labeled universal primers were utilized for cost effectiveness. Capillary fragment analysis yielded the accurate size of amplicons for evaluation of particular patterns for each cultivar. Phylogram and Structure analysis presented the specific genotype of genome groups (A and B genotypes, polyploid hybrid genomes) and cultivar groups. By A:B specific alleles ratio, accurate genome designations of hybrids can be determined. Additionally, a marker, characterized to be partial plastid ycf2 gene, indicated the maternal identification of hybrid cultivars. One SSR marker was also preliminary tested with some wild species and advised to be the candidate fingerprinting marker for species identification. In conclusion, SSR marker sets developed here proved their exploitation in detailed identity and relationship of cultivated bananas, which would be useful for genetic conservation and ongoing breeding programs in Thailand and other areas.

“…In contrast, inflorescences of Rhodochlamys are erect, the bracts are always bright in colour (often red), and the fruit are usually inedible (Cheesman, 1947). Musa chunii, a recently described species (Häkkinen and Hong, 2007), has a close relationship with Musa aurantiaca and Musa sanguinea (subclade E); each of these species has erect inflorescences and brightly coloured bracts and is distributed in Yunnan, China. SSR analysis revealed cross-clustering of Musa and Rhodochlamys species.…”

Musa L. was previously separated into five sections (Eumusa, Rhodochlamys, Callimusa, Australimusa and Ingentimusa) based on basic chromosome numbers and morphological characters. However, several molecular analyses currently support restructuring of Musa species into two sections, Musa and Callimusa. The application of simple sequence repeat molecular marker analysis to Musa phylogeny provided valuable, supplemental information about the classification of, and relationships between, Musa species and subspecies. Totally, 28 accessions of Musa acuminata Colla subspecies and varieties and 25 accessions of other Musa species were evaluated; 12 primers produced 91 polymorphic bands, polymorphic information content ranged from 0.4473 to 0.8394 (average ¼ 0.7226), indicating that the primers showed a high level of polymorphism. Our results generally agreed with previous phylogenetic analyses based on molecular data. One clade comprised species of sections Australimusa and Callimusa (X ¼ 10/9); most species of sections Eumusa and Rhodochlamys (X ¼ 11) formed the other clade. The relationships between most species were as expected; however, some species did not conform to findings of previous studies. A wide range of variability was observed in the M. acuminata complex. M. acuminata var. chinensis and M. acuminata subsp. 522 showed the most distant relationships to other subspecies: Musa laterita, Musa ornata and Musa velutina clustered with M. acuminata var. chinensis, suggesting that they may constitute a secondary gene pool for the improvement of cultivated bananas. Molecular data indicated that Musa tongbiguanensis Chen You & Yao-Ting Wu, which was observed and described by our research group in Yunnan, China, was a distinct, new species.

“…It has been estimated that Musa comprises about 70 species and over 500 cultivars, and new species continue to be discovered (Häkkinen and Hong 2007). However, many specific and infraspecific taxa are still confused and doubtful (Häkkinen and Väre 2008).…”

Banana inflorescences are popularly known as 'navels,' and they are used in Brazil as nutritional complements. However, the nutritional value of banana inflorescences (male flowers and bracts) has never been studied. Therefore, plant material of Musa acuminata, cultivar "ouro", was collected in Rio de Janeiro state, Brazil, and then submitted to chemical procedures to determine its nutritional composition. The experiment was arranged a completely randomized design and performed in triplicate. The sample composition analysis showed percentual average value for moisture, protein, fat and ash as 8.21, 14.50, 4.04 and 14.43, respectively. The dehydrated inflorescences were found to contain a significant nutritive complement based on their high content of potassium (5008.26 mg / 100 g) and fiber 49.83% (lignin, cellulose and hemicelluloses) revealing important functional and nutritional properties. In a parallel evaluation, the anatomical study revealed key elements for the recognition of Musa acuminata when reduced to fragments.
