The investigations on the effect of seed colouring of redgram, blackgram and bengalgram seeds encompassing 25 dyes were conducted to identify non-deleterious and deleterious dyes based on their effect on seed quality. The dyes namely Rhodamine-B, Fuchsine and Titan yellow for redgram, Rhodamine-B, Fuchsine and Phenol red and Rhodamine-B, Crystal violet, Titan yellow for bengalgram were found to be the best dyes for seen colouring at 0.75% concentration. In this paper we discuss developing colour standards for redgram, blackgram and bengalgram seeds and their resultant implications for Indian seed industry.
