Abstract

The occurrence of rust leaf disease (Tranzschelia discolor f. sp domesticae) was verified in 24 peach and nectarine selections at the Jundiaí Experimental Station (23°08'S and 46°55'W) State of São Paulo, Brazil. The trees of the germoplasm bank were evaluated using a sympton scale to evaluate selection susceptibility to the pathogen, at different levels. The less susceptible selections were: 1) peaches 'Regis' and IAC 4685-45 and 2) nectarines 'Josefina' and IAC N 2680-91.
