Abstract

Three pairs of near-isogenic lines of Vicia faba L. were bred that differed in anthocyanin-based pigmentation of the petals, one line within a pair having pigmented flowers, the other one white flowers. Condensed tannins, as determined by the vanillin-sulfuric acid method, were virtually absent in seed of the white-flowering genotypes. The isogenic lines, four parental genotypes and a commercial variety were compared with respect to resistance to soil-borne pathogens by exposing them to diseased soil in a controlled greenhouse. Plant resistance of white-flower lines or varieties was equal to or higher than that of antho-cyanin-pigmented genotypes. Emergence under conditions of cold-stress was significantly lower for one of the white-flower lines, but not so for the other two. Poor emergence was alleviated by a combined seed dressing of thiram and benomyl.

The present results seem to justify the conclusion that the disease resistance of white-flower, tannin-free faba beans depends on the genetic background and that tannin-free genotypes can be bred that have adequate levels of disease resistance under stress conditions.
