Abstract

The effectivity of Vada resistance against leaf stripe in barley varieties.

Abstract

Single-gene resistance to the Danish population of Drechslera [Pyrenophora] graminea found many years ago in some European varieties was traced back to Vada and Minerva, from a cross between Svalöf Gull and Hordeum laevigatum, and the resistance gene involved was linked to the laevigatum gene Ml-(La) for Erysiphe graminis resistance. When Golf, with the Vada-type resistance, was compared with the susceptible Triumph in yield tests after inoculation in the field, with and without seed dressing with fungicide, there was no D. graminea in Golf and seed dressing caused a non-significant yield loss, while 12.5% incidence of D. graminea in untreated Triumph led to 14.3% yield loss (0.92 t/ha).
