Abstract 

 The present study was carried out at seed testing Laboratory of the Department of Genetics and Plant Breeding, SHUATS Allahabad, U.P during Rabi 2020-2021 with marigold varieties Pusabasanti and Kalyan-2 This experiment was carried out inCRD for lab experiment (9 Traits with 4 Replications). The experimental observations summarized below based on the objectives and traits under taken in the study. The study revealed that  when varieties primed with T₁₀ (GA3 100 ppm) resulted in increase of Germination percent, Speed of germination, Root length, Shoot length, Seedling length, Fresh weight, Dry weight, Vigour index I, Vigour index II . GA3 performed better among other treatments and enhanced seedling characters followed by T₉ (GA₃ 50 ppm), T₁₂ (NAA 50ppm). By the study it can be recommended that marigold  seedlings  characters are improved with the application of GA3.

Keywords: GA3, marigold, priming, speed of germination, seedling characters etc.
