Abstract
Characterization of restorer lines of rice based on seedling and plant morphology contributes in assessment of varietal identity and further its utilization in development of hybrids. With this objective the work was carried over with 90 restorer lines with three replications during Kharif season 2018. The experiment conducted under Rice Improvement Project at Seed Breeding Farm, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (M.P.).Out of 41 morphological traits as per DUS guidelines, variability was reported for all traits except leaf sheath anthocyanin colouration, presence of leaf auricle, presence of leaf collar, presence of leaf ligules, white colour of leaf ligules, absence of stem anthocyanin colouration of internodes, male sterility and presence of secondary branching in panicle. The genotypes Mahamaya, ANP-526 and ANP-553 revealed distinctness for most of the traits.
