Abstract:

Mutation breeding is an effective approach in improvement of crop having narrow genetic base such as soybean by creating variability. Studies on variability, heritability and genetic advance on yield and yield contributing characters are the pre – requisites for selection of parents. Hence, 283 M4 mutants along with their parents viz., Co (Soy) 3 and JS 335 were raised in Randomized Block Design (RBD) with two replications at Department of Pulses, Centre for Plant Breeding and Genetics, TNAU, Coimbatore, during Kharif 2013. In the present investigation, high PCV and GCV coupled with high heritability was observed in plant height, number of clusters per plant, number of pods per plant, seed yield per plant and phytic acid content. This indicates the lesser influence of environment in expression of these characters and prevalence of additive gene action in their inheritance. Hence, these traits are amenable for simple selection.


Keywords: Soybean, Variability, Heritability, Genetic Advance as per cent of Mean, M4 Mutant lines.
