The present experiment conducted in the period of rabi season at Sorghum Improvement Project, M.P.K.V., Rahuri, Maharashtra during the period of 2016 to 2017. During investigation to observed the physiological parameters under non stress and moisture stress condition with cross two genotypes SPV 1830 x IS 6427. In this study of mean performance of the basic generation P1, P2, F1, F2, B1 and B2 of the cross SPV 1830 x IS 6427 was observed various physiological parameters viz. photosynthetic rate, rate of transpiration, stomatal conductance, relative leaf water content, SPAD reading, total chlorophyll content and chlorophyll stability index. The present results to observed the B₂ and F₁ generation recorded significantly highest photosynthesis rate (25.98 and 22.47 µ mole CO₂ m-²s-¹) under non stress and moisture stress condition, respectively. The parent B₁ recorded highest transpiration rate (3.27 and 1.92 mmole H₂O m-²s-¹) under non stress and moisture stress condition, respectively. The F₁ and B₁ generation recorded significantly the highest mean for stomatal conductance (0.24 and 0.18 mole m-² s-¹) under non stress condition and moisture stress condition, respectively. The B₁ generation recorded the highest total chlorophyll content (3.30 and 2.08 %) under non stress and moisture stress condition, respectively. The present experimental study to observe physiological parameters of sorghum cross two genotype (SPV 1830 x IS 6427)   directly affected in growth and grain yield under non-stress and moisture stress condition. Therefore, present study to find out the drought stress effects on sorghum through the physiological parameters.
