Description :
Chickpea (Cicer arietinum L.) is most important pulse crop among the legumes. It is rich in protein. In spite of its importance it has narrow genetic diversity. Morphological mutations affecting almost all the parts of the plant and seed characteristics were isolated in M2 generation of a popularly grown cultivar of chickpea, Phule G-81-1-1 (Vijay), treated with chemical mutagens, sodium azide (SA) and ethyl methane sulphonate (EMS). They included leaf, pod, seed, flower colour and morphological mutants. A high frequency of viable mutations was observed with EMS followed by SA treatments.The small leaf mutant with better canopy was isolated in M2 generation from 12 mM EMS treatment. Breeding behavior of this mutant was studied for various quantitative and qualitative traits in M5 generation. True breeding mutant lines in the M5 generation differed considerably in their quantitative traits from the control. Induced mutant lines showed both positive and negative increases in quantitative traits. The yield and yield contributing traits and protein content were studied during the M5 generation. The mutant showed the increased, plant spread, number of pods per plant and number of seeds per plants. The protein content and protein profile showed variation as compared to control. Keywords: chickpea, EMS, mutagenesis, SA.
