Resistance to Pseudomonas solanacearum in the potato: II. Aspects of host-pathogen-environment interaction

Abstract: Host-pathogen-environment interaction in the potato -P. solanacearum pathogenic system was investigated by testing eight true potato seed progenies and four clones for resistance to three potato isolates of P . solanacearum under two temperature regimes . Highly significant interactions of all types : progeny x isolate, isolate x temperature, progeny x temperature, and progeny x isolate x temperature were observed . Changes in pathogenicity of isolates with temperature were the major source of the total variat… Show more

“…Germplasm showing resistance to R. solanacearum at high altitudes often becomes susceptible when grown at warmer temperatures in the lowlands (French and De Lindo 1982;Tung et al 1990). This suggests the existence of latent infections (i.e., infected plants that remain asymptomatic), adding further complexity to breeding programs for resistance to bacterial wilt.…”

“…It is considered a threat because it can cause disease at cooler temperatures than tropical R. solanacearum strains and is widespread in the cool highland tropics (8,9,45,46). If R3bv2 could overwinter in the harsher climate of the northern United States and Canada, it could threaten the $4 billion North American potato industry (http://www.agr.gc.ca/).…”

“…'Achat' mostrou maiores níveis de doença do que os observados em testes anteriores, quando alternavase com a 'Cruza 148' em termos de resistência (Lopes & Quezado Soares, 1995). Este fato se deve à interação do patógeno e da hospedeira com fatores 33 -131433 - ,72 11, 26, 7, 13, 5, 17 -4 151933 - ,03 -197833 - ,95 25, 18, 28, 16, 10, 21, 8 Bintje (1978 ambientais (French & De Lindo, 1982;Schmiediche, 1985;Tung et al, 1990a;Tung et al, 1990b). Conforme indicado por , 'Achat' não é indicada para plantios sujeitos a temperaturas elevadas, como observado no período do ensaio (média das temperaturas máximas acima de 28 o C).…”
