SUMMARY
An experiment comprising 32 different genotypes of oat was conducted during rabi 2021 in four different environments. In each environment each genotype was sown in a two-row plot of 2.5m length in randomised block design with two replications. Observations of five randomly plants of each genotype in each replication were recorded on ten different characters viz., days to 50% flowering, plant height(cm), leaf length (cm), leaf width (cm), number of tillers per plant, green fodder yield (gm), leaf dry weight per plant (gm), stem dry weight per plant (gm), leaf stem ratio, dry matter weight (gm), days to maturity and plant population. Analysis of variance revealed that significant differences existed among genotypes for all the characters in all four environments. High estimates of broad sense heritability along with high estimates of genetic advance as percent of mean was observed for green forage yield, leaf dry weight, stem dry weight, leaf stem ratio in all the three environments.
Key words: Oat, Variability, Heritability, Genetic advance
