Relationship Between Physiological Traits and Seed Yield of Ocimum Genotypes

The present investigation was carried out to study the physiological traits and productivity of Ocimum genotypes during kharif season of 2007–2008 in randomized block design with three replications at medicinal and aromatic plants, department of crop physiology, college of agriculture, J.N.K.V.V., Jabalpur (M.P). The results revealed that genotypes AIC 369247 recorded higher magnitude (1534.40 μ mol/m²/sec)) of photosynthetically active radiation (PAR) interception, net photosynthetic productivity (28.97 μmol/m²/sec) and H₂O utilization (1.023 KPa) reflected in maximum leaf area index and net assimilation rate (1.18 dm/m² and 0.070 mgcm⁻²day^{1). The genotypes AIC 369247 also had highest seed yield (2097.9 kg/ha) followed by O. basilicum JBP (2088.9 kg/ha), owing to more number of inflorescence per plant (170.3 and 156.7) and higher number of seeds per inflorescence (951.7 and 720.0).}
