Overcoming barriers to the registration of new plant varieties under the DUS system

C. J. Yang, J. Russell, et al.

Explore the evolving challenges of the Distinctness, Uniformity, and Stability (DUS) system for plant variety registration in this compelling study analyzing 805 UK barley varieties. Conducted by Chin Jian Yang, Joanne Russell, Luke Ramsay, William Thomas, Wayne Powell, and Ian Mackay, this research reveals significant deficiencies and presents an innovative 'genomic DUS' system, poised to revolutionize registration processes.

Abstract
The Distinctness, Uniformity, and Stability (DUS) system, crucial for plant variety registration, relies heavily on morphological traits despite advancements in crop biology. This paper evaluates 805 UK barley varieties to highlight DUS system deficiencies, including inconsistencies across environments, limited trait combinatorial space, and inadequate markers. The authors advocate for "genomic DUS," a genomics-enabled registration system, providing evidence for its robustness and advantages.
