Abstract

This article focuses on identifying and evaluating wild tuber-bearing (WTB) Solanum species for de novo domestication to develop more resilient potato crops. From 107 known WTB species, ten were selected based on literature for their resistance to biotic and abiotic stresses, tuberization under long- and short-day conditions, steroidal glycoalkaloid (SGA) content, starch digestibility, and tissue culture performance. Among these, Solanum bulbocastanum emerged as the prime candidate due to its broad-spectrum pest and disease resistance, ability to tuberize under long-day conditions with relatively large tubers, high regeneration efficiency in vitro, and a distinct SGA profile dominated by α-tomatine, which is less toxic to humans than the SGAs found in cultivated potatoes. The study highlights the potential of applying gene editing to introduce domestication traits such as reduced SGA content and improved tuberization into S. bulbocastanum, supporting its development as a climate-resilient, sustainable potato crop.
