Abstract: The experiment was conducted during 2016-2017 at Division of Plant Genetic Resources, ICAR-Indian Institute of Horticultural Research (ICAR-IIHR), Hessarghatta, Bengaluru. Genotypic variability, heritability and genetic advance for yield and yield contributing traits were studied in ten <em>Oroxylum indicum</em> (L.) Vent. accessions. Data were recorded for plant height (m), stem girth (cm), leaf length (cm), leaf width (cm), petiole length (cm), leaf area (cm²), number of pods per tree, pod length (cm), width of pod (cm), number of seeds per pod, pod yield (kg/plant). Among different yield attributing characters studied, the highest magnitude of PCV and GCV were recorded in leaf area (26.869 and 27.827 %), number of pods per plant(36.593 and 37.610 %) and pod yield per plant (46.319 and 46.912 %).High heritability coupled with high genetic advance as per cent over mean was recorded for the characters <em>viz., </em>leaf length (90.30 %), petiole length (85.20%), leaf area (93.20 %), number of pods per tree (94.70 %) and pod yield per plant (97.50 %).Hence, these characters were predominantly governed by additive gene action and could be used as a selection criterion for breeding programmes in the future.
