The present investigation entitled “Morpho-physiological characterization of inbred lines in maize” was carried out during rabi 2019-20, at research field of Agriculture Research Station, Buldana. The experiment was laid out in RBD design with three replications and eleven inbred lines. viz., BMI-6-2-2BMI-28-1, BMI-34-3, BMI-23-1, BVM-21-1, MGT-53-2-1, MGT-53-36, MGT-53-23, MGT-53-24-4, V1543-6-12, V1551-15. Sowing was done by dibbling method on 21^st December 2019 at a spacing of 60 x 20 cm. There after all the intercultural operations were done as and when required. The recommended dose of 120:60:40 NPK kg/ha was applied. Morpho-physiological parameters were recorded at 30, 60 DAS and at harvest, days to 50% tasseling and silking was recorded at the proper stage. Growth parameters were recorded at 30-60 and 60-harvest. Biochemical parameter was recorded at 30 and 60 DAS. Yield and yield attributes were recorded at harvest.

Result revealed that, significantly maximum values of morphological parameters like plant height (cm), leaf area (cm²), leaf area index were recorded in Inbred line V1551-15; physiological parameters like dry matter production (g), relative water content (%) were recorded in inbred line MGT-53-2-1. Form overall results it can be concluded that Inbred line V1551-15 was found to be superior for morphological parameters. Hence, they can be utilized for improving morphological and physiological, and for further breeding programme.
