Behaviour in the field and in the glasshouse of some genes of resistance to Puccinia recondita f.sp. tritici

In the field, the most effective resistance genes of adult plants were Lr 9, Lr 12, Lr 13, Lr 15, Lr 19, Lr 24 and Lr 25. On seedlings in the greenhouse, genes Lr 9, Lr 19, Lr 20, Lr 24 and Lr 25 were effective against all the isolates.

Behaviour of Aegilops species with respect to Puccinia recondita f. sp. tritici, Puccinia graminis f.sp. tritici and Erysiphe graminis f. sp. tritici. Seedlings of strains of a number of Aegilops species were inoculated with three biotypes of P. recondita (B22, B21 and B9), corresponding to physiological races 211, 12 and 77 respectively, with one biotype of P. graminis (N21), corresponding to p...
