Mutagenesis in hundred seed weight of okra (Abelmoschus esculentus L. Moench).

Navnath G. Kashid


The induced mutations display a pleiotropic effect due to which several features are changed only one of which however is desired by the breeder. The cross of two mutants can occasionally break undesired pleiotropic effect and valuable transgressions in other features can be achieved. Since majority of point mutations are recessive, the search for deviating phenotypes does not begin until the M2 generation. The determination as to whether a detected variant is a mutant or non-heritable modification can only take place in M2 generation after testing its progeny.

     Datta (1994) has indicated the utility of mutation technique in producing large number of new promising varieties in different ornamentals like chrysanthemums and roses.

. The major objective in employing induced mutations has been to increase variability within shortest possible period and to develop some such genotypes which could carry attributes of immense economic value. Due to mutation breeding okra varieties increased number of fruits per plant, seeds per fruit and seed weight
