Abstract:

The mutagenic effectiveness and efficiency of gamma rays was studied on greengram breeding lines with dose of 20 kR and 100 kR for creation of desirable variability. These two parameters are the measures of usefulness of a particular mutagen for a particular crop genotype. Highest mutation frequency was found in the breeding lines of DGGV-2 × IPM-410-3 (11.42%) and DGGV-2 × SML-1815 (7.27%) with 100 kR. The mutagenic effectiveness was highest in the breeding lines of DGGV-7 × V-02-709 with 0.25 at the dose 20 kR, whereas the lowest (0.07) was observed in DGGV-2 × SML-1815 with 100 kR. The average mutagenic efficiency was highest in the breeding lines of DGGV-7 × V-02-802 (0.39). Hence, the mutagenic effectiveness was decreased with increased dose of mutagen, while the mutagenic efficiency was reported higher in lower dose of mutagen as the higher dose causes reduction in germination percentage and more lethal plants.
