Natural Polyploids in Cucurbitaceae I. Cytogenetical Studies in Triploid<i>Momordica Dioica</i>Roxb.

Abstract

SUMMARYCytomorphological studies have been carried out in a naturally occurring triploid male plant of Momordica dioica. Different vegetative and floral parts of these triploids were found to be intermediate between diploids and natural tetraploids. Meiosis was highly irregular, forming trivalente and univalents. Pollen fertility was very low (about 2%). This triploid has been used in crossing experiments from which some fruits and seeds have been obtained.
