Abstract

Abstract

Common root rot caused by Cochliobolus sativus (Ito et Kurib) Drechs. ex Dastur causes substantial loss in spring wheat (Triticum aestivum L.) in the northern USA and Canada. This study was done to test hard red spring wheat cultivars and lines for susceptibility to common root rot. Spring wheat genotypes were planted in Fargo, ND, in eight field experiments from 1977 to 1990 on a Fargo silty clay (Vertic Haplaquoll). Genotypes exhibited a continuous range of response from susceptible to moderately resistant but none were entirely free from disease. Eight genotypes equalled or exceeded the level of resistance of ‘Thatcher’, long considered the standard for a high level of resistance to this disease.

Published with the approval of the director, North Dakota Agric. Exp. Stn. as Journal Series no. 2107.
