Bananas are one of the most economically and socially important fruits in the world. The continuous obtaining of new varieties is crucial to increasing the resilience of the banana production chain. One of the main breeding methodologies is the crossing of commercial varieties with improved diploid varieties. Thus, this study evaluated the germination rate of three improved diploid banana genotypes over twelve months, analyzing and comparing the average monthly and total germination rate of each accession and observing the fluctuation of the germination rate within each genotype over the months evaluated. A genotype dependence was observed in the average monthly and total germination rate, with genotype 4223-06 presenting higher monthly and total germination rates. It was also observed that in all genotypes there was a fluctuation in germination throughout the months evaluated, with a higher germination rate in the months of the first half of the year, highlighting the meteorological seasons of summer and autumn.
