The current system of plant variety protection and registration using assessment of DUS (Distinctness, Uniformity, and Stability) characteristics predominantly relies upon morphological traits which are quite laborious, time‐consuming, requires skills, expertise, and evaluation under special designs for most quantitative traits. With the advent of novel breeding technologies, new varieties differ only for few traits or at few loci which make the process of detecting distinctness in varieties, a challenging task. Even with increasing numbers of plant varieties, DUS testing is becoming quite expensive. In a review by Jamali et al. (2019), DNA‐based molecular markers have been proposed to be a reliable alternative for conducting DUS testing. Molecular markers not only cut cost, time and labor but will also help in the proper sharing of Plant Breeder’s Rights with an assessment of few distinct traits, particularly in essentially derived varieties.
