Cytological observations on the naturally occurring mutant gram have been described. The mutant was found to be an autotetraploid with 2
Detailed and critical analysis of morphology of the individual chromosomes in the somatic complements of the diploid as well as tetraploid types has been given for the first time.
Decrease in size of chromosomes with increase in chromosome number was not observed in the case of the mutant studied.
The coefficient of multivalency was found to be fairly high in the mutant which indicated that continuous selection in the selfed progenies would be necessary for some years.
Maximum germination of pollen grain was obtained on 12% sugar solution in the case of tetraploid gram and on 71/2% in the case of diploid gram which indicates that the tetraploid gram has higher osmotic pressure indicative of higher concentration of water-soluble cell contents.
