Resistance of triticale to wheat leaf rust (Puccinia triticina)
Czech Journal of Genetics and Plant-Breeding 47 (1), 10-16
Abstract: Reactions of winter triticale cultivars mostly from central Europe to recent and old leaf rust isolates were tested in the greenhouse. In one trial 20 cultivars were tested with 8 leaf rust isolates, collected recently from official wheat and triticale trials in the Czech Republic and Slovakia. In another trial 15 cultivars were tested with 6 old leaf rust isolates, used to identify leaf rust resistance genes in wheat. The cultivars Cando, Hortenso and Tricolor, registered in the Czech Republic, were resistant to the majority of the recent isolates. The Hungarian cultivar Tatra was resistant to all the recent isolates. The old leaf rust isolates were virulent only to a few of the triticale cultivars. Randomly selected isolates from wheat and triticale were tested on triticale cultivars and on Thatcher near isogenic lines with different Lr genes. On average, leaf rust isolates from triticale were virulent to a higher number of triticale cultivars than isolates collected from wheat and vice versa.
