A study was undertaken in the laboratory of National Seed Project Shalimar and in the laboratory of Department of Genetics and Plant Breeding, Faculty of Agriculture, Wadura during 2019-2021. The objective of the present study was to standardize the hydro-priming technique in two maize hybrids SMH-3 and SMH-5 and to know the physiological changes associated with the priming in maize seeds. Different combinations of temperature and duration of soaking were tested and the most efficient priming temperature was 25±1ºC and the ideal duration of soaking was 24 h. All the physiological attributes like first count, final count of germination, T50, BRI, MSL, MSDW, SVI-I, SVI-II were significantly higher in both hybrids and their parental lines than the non-primed maize seeds.
