Induced Chemical Mutagenesis for the Improvement of Yield Attributing Traits and their Correlation Analysis for M1 Generation of Chickpea (Cicer arietinum L.)
Ramreddy Sindhuja Reddy | Gabrial M. Lal
Abstract: Four widely adopted Chickpea genotypes SABOUR CHANA - 1, BRC - 5, BRC - 100 - 84, IPC 2012 - 49 were induced by chemical mutagen with different concentration (0.01%, 0.02%, 0.04%, 0.06%, 0.08% with SA) of sodium azide (NaN3) and soaked with the above mentioned treatments for about 6hrs at the post graduate laboratory and were sown at field experimentation center, Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agricultural, Technology and Sciences, Prayagraj, U. P (Rabi - 2019). For study of micro - mutation, randomly selected fifteen plants were selected from each concentration/treatment lines were selected and threshed separately. A trail laid in randomized block design with three replications. In the present study, the treatments showed that maximum GCV and PCV for seed yield per plant (54.94 & 52.964), biological yield (39.10 & 40.2), number of effective pods per plant (30.793 & 31.70) in M1 generation. Heritability and genetic advance were recorded maximum for number of pods per plant (94.40% and 16.01%) and number of effective pods per plant (91.6% and 14.77%). High heritability coupled with genetic advance was recorded for seed yield per plant (98.2% and 96.18%) followed by biological yield (95.40% and 78.68%) in M1 generation. Seed yield was positively correlated with days to 50% flowering, seed index, biological yield and harvest index at the both genotypic and phenotypic levels in M1 generation.
