Abstract: The experiment was conducted in Post Graduate Laboratory, Department of Genetics and Plant Breeding, Sam Higginbottom University of Agriculture, Technology and Sciences, Allahabad (U.P.), in order to standardize the suitable method of priming for Wheat seeds (var. DBW-17). Four methods of priming viz., T₁-Unprimed (Control), T₂ and T₈ Hydro-priming with Distilled water, T₃ and T₉ Osmo-priming with PEG 20%, T₄ and T₈ Halo-priming with NaCl 1%, T₅ and T₁₁ Halo-priming with CaCl₂ 1%, T₆ and T₁₂ Organic priming with Tulsi leaf extract 5% and T₇ and T₁₃ Organic priming with Neem leaf extract 5% hydration for 8 and 12 hours respectively. It was found that among all the priming showed significance difference with the control and the highest germination percentage (%), germination index, energy of emergence, seedling length (cm), seedling fresh weight (mg), seedling dry weight (mg) and vigour indices were observed in CaCl₂ priming for 12 hours. This study also showed that Seed priming with CaCl₂ were found to increase the seedling characters. The seeds treated with CaCl₂ (1%) hydration 12 hours followed by CaCl₂ (1%) hydration 8 hours and PEG (20%) hydration 8 hours recorded numerically higher values but for energy of emergence and for germination index second best was Neem leaf extract 5% hydration 12 hrs and for dry and fresh weight PEG (20%) hydration 8 hours was higher value compared to control. The study helps to improve the seedling character, growth of seeds with the help of seed priming treatments which are cost effective, economic, non-toxic and eco-friendly sources.
