Investigations on artificially induced tetraploids of radish and white cabbage varieties

, : Investigations on artificially induced tetraploids of radish and white cabbage varieties. J. Hort. Ass. Japan. 18: 121-28

Tetraploid strains of 10 radish, 11 white cabbage and a few other types of cabbage were produced and compared with the parent diploids. In general, the tetraploids were less vigourous or as vigourous as the diploids, while flowering was usually delayed. In the radish variety Manchurian Red Globe, the tetraploid flowered earlier. Seed production in the tetraploids was reduced. Self compatibility in the tetraploids was lower in the bud but higher in the flower.

Our hypothesis was that the r...
