SUMMARY

The present study on variability and character association in fodder oat was carried out at Forage Research area, Department of Genetics & Plant Breeding, CCS HAU, Hisar during rabi 2010-11. The results revealed that the magnitude of genotype and phenotypic coefficient of variation was moderate for dry mater yield, number of fellow/m and green fodder yield. The green fodder yield had maximum positive direct on dry fodder yield followed by plant height and number of tillers/m though heritability estimated accomparied with moderate genetic advance were observed for dry matter yield and green fodder yield. 

Key words : Variability, correlation, path analysis, heritability genetic advance, fodder oat
