The study was conducted to standardize an efficient protocol for callus induction, subsequent growth and in-vitro regeneration in six genotypes of proso millet viz., Gavhe, Sakhroli, Kalsuli, Vari No.10, Asond and Sukdhar. The seeds were surface sterilized with 70% ethanol for 1 minute + 1% HgCl2 for 10 minutes recorded maximum aseptic culture establishment in all genotypes. The mature embryo (seeds) of proso millet was cultured on MS medium supplemented with varying concentrations of 2,4-D (0.1-2.0 mg/l) and NAA (1.0-4.0 mg/l) NAA for callus induction for their callus induction and subsequent growth. Maximum frequency of callus induction was observed on MS media supplemented with 2 mg/l 2,4-D + 0.5 mg/l BAP. MS media supplemented with 2, 4-D produced friable, white and yellow colour calli while, in the same media supplemented with NAA produced loose light yellow and loose white colour calli. Maximum shoot regeneration was achieved by transferring calli on MS media supplemented with 4mg/l BAP and 4mg/l Kinetin. These regenerated plantlets were significantly showed rooting, when transferred on full strength MS supplemented with 0.2mg/l IBA + 0.1mg/l BAP and 2% sucrose. The rooted plantlet was hardened and transferred to soil.
