In recent years, several rapid multiplication techniques have been developed for quick potato multiplication. These techniques aim to improve the efficiency and speed of potato seed production. Under conventional system, an attempt was made to evaluate the sprout cutting as a rapid multiplication technique (RMT) which can be a valuable technique for farmers without access to hi-tech systems. Healthy tubers of seven varieties, viz., K. Jyoti, K. Lauvkar, K. Chipsona-3, K. Sindhuri, K. Surya, and K. Chandramukhi, were used for the study. Desprouting was performed three times within 40–45 days (to fit in seed window), leading to a high multiplication rate of 10.5–18 sproutlings per tuber, depending on the variety. Sprouts were harvested every 10–15 days, and the number of sprouts increased with each harvest. Ultimately, the multiplication rate exceeded one hundred minitubers per tuber for all tested varieties. This method provides an efficient alternative for farmers and seed growers who may not have access to advanced technologies, ensuring a high multiplication rate and maintaining seed health. It is ideal to use indexed tubers for multiplication through sprouts.
