Kodo millet is one of the important small millet rich in nutrition and has the ability to withstand extreme climatic conditions. Since. It is a highly self pollinated crop variability in this crop is limited. Mutation and selection is one of the breeding approach carried out to induce variability and helps in the selection of better performing mutants for the future use. The present investigation was carried out to study the relationship between progenies of 67 families of M₄ and M₅ mutants of Kodo millet. Observation on the traits, Stomatal Length (µm), Stomatal number, Chlorophyll Index, Culm thickness (cm) and Yield (g) were the key traits for selection. The regression analysis shows that there was a strong relationship between two generations M₄ and M₅. Intergeneration correlation was positively significant among M₄ and M₅ generations revealing traits are heritable to the further generations. Higher narrow sense heritability was observed all the traits except Stomatal length and Chlorophyll index which showed moderate heritability. This suggests the traits are governed by additive gene action. Selection on these generations based on the traits would be rewarding and focus on the improvement of the population
