The present study was carried out to estimate the extent of variation for qualitative traits for advanced mutant generations of oat. Observations were recorded for the different agro-morphological characters viz., plant growth habit, ligule shape, leaf blade hairiness, leaf blade hairiness, recurved flag leaves, stem width, leaf width, leaf color, panicle attitude. Characterization of accessions provides the important information about morphological and agronomical aspects of the material that is essential for gene bank management. | Morphological characterization of advanced mutant lines of oat Avena sativa L.
