Abstract

Cytogenetics of the different varieties of banana from Batangas, namely Musa sapinetum var. cineres (latundan), Musa sapientum var. lacatan (lacatan), and Musa sapientum var. compressa (saba) were examined through microscopy of the squashed, lacto-aceto-orcein stained meristematic cells of the root. The chromosome behaviour of the meristematic cells during mitosis was characterized through the appearance of the chromosomes, relative chromosomes lengths during metaphase and presence of chromosomal abnormality. All cultivars manifested normal mitotic division. Mitotic index of the cultivars was determined and was suggested to be in association with growth and survival rate of the plant. Musa sapientum var. cineres (70.77%) has the highest mitotic index followed by Musa sapientum var. lacatan (61.36%), and lastly, Musa sapientum var. compressa (48.57). Thus, Musa sapientum var. cineres has the highest survival rate with shortest gestation period while Musa sapientum var. compressa has the lowest survival rate with the longest gestation period.
