Abstract

1. Microsporogenesis of the three most common varieties of edible bananas, Pei Cha, Sen Jen Cha, and Feng Cha on the Island of Formosa were studied and illustrated. 2. All of them are triploids, being with 33 somatic chromosomes. 3. The chromosome configurations of these 3 varieties are very diverse, although their chromosome size and shape can not be identified, owing to the smallness of the banana chromosomes. 4. Although Pei Cha and Sen Jen Cha are morphologically similar, their chromosome configurations are very different. The cause of such difference and the possible origin of Sen Jen Cha were discussed.
