Abstract
Wilt disease is a significant constraint in linseed production, necessitating the identification of resistant cultivars. This study evaluated 23 linseed cultivars under high inoculum pressure in both pot and field conditions during the 2023-24 and 2024-25 growing seasons. Wilt incidence varied significantly among the entries, with some exhibiting strong resistance and others showing high susceptibility. RLC-92, RLC-148 and Selection EC-99001 recorded the lowest wilt incidence across both conditions and years, while NL-260 and IC0499042 exhibited the highest susceptibility. The findings suggest the potential for selecting resistant cultivars for breeding programs and improving linseed productivity.
