Abstract
Potato (Solanum tuberosum L.) is one of the most economically significant annual vegetable crops occupying the fourth position worldwide among all the food crops. The main drawbacks of the traditional seed production method are the seed tubers' high size, which drives up seed production costs, the ease with which viruses and other diseases can damage them, the slow rate of seed multiplication, and the lengthier time it takes to obtain breeder seed. There are various benefits to the invention and use of microtubers in potato farming. It is not necessary to acclimatize or move to a different medium when growing microtubers because they can be kept for up to a year and then transported straight to the market. By doing this, the field cycle needed to produce a sufficient amount of seed potatoes is greatly reduced, and a high quality of materials is guaranteed. Shoot tip and node or internodal explants, which have a survival probability of about 90%, are frequently used in the process of in vitro plant regeneration. Positive outcomes in stimulating shoot formation have been observed when Murashige and Skoog media enriched with benzyl amino purine (BAP) and kinetin is used. Furthermore, employing the MS medium has been reported to maximize the effectiveness of microtuber induction in potatoes. It's been found that exposing the plants to a 16-hour photoperiod and complete darkness can improve the effectiveness of microtuber induction even further. Ultimately, this review study offers an appropriate method for a successful pathway in the in vitro regeneration of potatoes by carefully examining prior scientific data.
