SUMMARY

The present investigation was carried out to evaluate 118 mutant oats including three checks JO-1, JO 03-91 and Kent for association among traits and to judge the direct and indirect effect of
various yield and its attributing traits in pooled of M4 and M5 generation. The study were conducted during Rabi season 2016-17 and Rabi 2017-18 under All India Coordinated Research Project on Forage Crops, Seed Breeding Farm, JNKVV, Jabalpur. Data obtained for correlation and path studies suggested the most important traits observed among the mutant lines were dry matter yield per plant per day, thousand seed weight, plant height hence, direct selection may be effective for the improvement of these characters because these traits had highly significant and positive correlation along with direct positive effect with dry matter yield per plant. Whereas, the characters crude protein yield per plant, crude protein yield per plant per day and panicle weight were also found important as, indirect selection through such traits may be effective in yield improvement as the correlation is mainly due to indirect effects of the character through other component trait. Moreover, these traits can be considered for
formulating plant ideotype and selection based on these characters shall be rewarding for higher yield.

Key words: Correlation, yield, ideotype, selection, crude protein
