Abstract
Along with other South East Asian countries Indonesia is one of the homeland of bananas and is considered as a center of diversity of the genus Musa plants.However, given the vastness of Indonesia, the diversity of banana germplasm, especially in Lampung—oneof Indonesia's provinces on the island of Sumatra, has not been fully known.This study aimed to determine ploidy levels of banana germ plasm in the City of Bandar Lampung, based on the number of chromosomes. Banana plant sampleswere taken randomly from the back yard in 12 districts out of 20 districts in Bandar Lampung. The banana collectionswere then grown in soil media in polybagsand the secondary roots grown were taken for chromosomal preparationusing a modified squash method. The microcospic slide imageswere scanned and computerize analyzed to determine the ploidy level of banana germ plasmaby assessing the number of chromosome.The result showed there are 27accessions of the banana from two genera sections of Musa, 26 accessions belong to the Eumus section and 1 accession allegedly belongs to the section of Rhodhoclamys. Amongthe 27 accessions of bananas,6 accessions showed chromosome number2n = 22, 19 accessions have chromosome number2n = 33, and the last 2accessions have chromosome number 2n = 44.Itcan be concluded that the banana germplasm accessions in the city of Bandar Lampunginclude 3 ploidy levels, namely diploid (2n = 2x), triploid (2n = 3x) andtetraploid (2n = 4x). Keywords: Ploidy, banana germplasm, chromosome number, banana accessions
