description: Resistance of tomato fruits to Phytophthora infestans  Late blight, caused by Phytophthora infestans (Mont) de Bary, is one of the important  diseases in organic potato and tomato production. While some information on foliar  disease resistance of tomatoes is available, virtually no information exists on the  relation of leaf to fruit resistance.  The central parameters of the infection chain, incubation and latency period were  determined for 40 tomato varieties using three isolates of P. infestans. A total of 2858  fruits were drop inoculated in the lab and assessed daily for symptoms or sporulation  for 16 days.  There were significant variety by isolate interactions for incubation period, latency  period and the interim time suggesting race specific interactions with tomato fruits. A  Manteltest showed that the distance matrix of the isolate x variety interaction of leaf  and fruit reactions were not correlated. Thus, it appears that fruit and leaf resistance  are independent characters.
