Studies on seed colouring in redgram, blackgram and bengalgram

Abstract

Experiments were conducted to study the effect of seed colouring of red gram, black gram and bengal gram seeds encompassing 25 dyes to identify non-deleterious and deleterious dyes based on their effect on seed quality. The dyes namely Rhodamine-B, Fuchsine and Titan yellow for red gram; Rhodamine-B, Fuchsine and Phenol red for black gram; and Rhodamine-B, Crystal violet, Titan yellow for bengal gram were the best dyes for seed colouring at 0.75% concentration. The development of colour standards for red gram, black gram and bengal gram seeds and their implications for the Indian seed industry are also discussed
