Colchitetraploids were produced in a pure white flowered variety of Phlox drummondii, a
garden ornamental, and studied for morphological and cytological characters for three
succe..ive generations. Flowers were bigger and their longivity was increased by "-5 days
in the colchiploids, thus, increasing their ornamental value. There was a sudden drop in
quadrivalent frequency from Co to Ct generation and this tendency was maintained in C2
also which lead to rapid cytological diploidization of the colchiploids in the second
generation itself.
