Study on the relationsidp of 73 introduced And indigenous. Banana accessions basd on qualitative morphological characters

Abstract

In order to characterize the potential of banana (Musa spp) germplas1JI, 73 accessions consisting of 27 accessions introduced from INIBAP (International Initiative of Banana and Plantain) and 46 accessions of indigenous banana are subjected to relationship analysis through 22 qualitative morphological characters, including pseudostem, petiole, and lamina. Characterization based on scoring method of banana descriptor of IPGRI (International Plant Genetics Resources Institute). Similarity analysis reveals that distance among banana accessions genetics ranges at 0.0-1.0 of similarity value. Highest genetics similarity (1.0 level of similarity) is shown by banana accessions introduced from INIBAP (International Initiative of Banana and Plantain) or FHIA25 group. On the contrary, lowest genetics similarity (0.0 level of similarity) is shown by INIBAP accession of AAcv Rose with indigenous accession of Ambon Amerika B, and Trio/in. Dendogram generated by using SAHN-UPGMA (Sequential, Agglomerative, Hierarchical, and Nested -Unweighted pair­ group method, arithmetic average) indicates that the evaluated accessions separates at 0.21 coefficient of similarity, subsequently at 0.38 coefficient of similarity, the accessions are divided into seven groups. Among those groups, two groups are exclusively, consisting of 1NIBAP accessions, one group consists of indigenous accessions, and the other four groups hared by INIBAB accessions and i digenous bananas.
