Morphological characterization and yield performance of indigenous banana cultivars (Musa sp.) in Bangladesh in reference to geographical indicator (GI)

Abstract

In Bangladesh, bananas are the leading fruit crop, supplying more than 20% of total fruit production. This fruit was unique because of year-round availability, diversity, nutritious value, and consumer preference. More than 100 banana varieties are found in different parts of the country. Therefore, the morphological characterization of indigenous banana cultivars is especially significant in terms of geographical indication (GI). Thus, this research aims to characterize different cultivars of bananas facilitating GI protection of physical properties and plant genetic resources as part of variety development, economic growth, export and sustainable agricultural development. Fifty-five indigenous accessions were collected from different parts of the country, and their morphological features (e.g., colour, weight, length, diameter, presence of seed, yield) were compared. Significant variations were found among the collected accessions. More than 50% of the indigenous accession yielded more yield than popular commercial varieties, indicating good market value and export potential. The research findings could add significant insights for identifying indigenous banana cultivars for GI registration.
