Quantitatively expressed resistance to anthracnose (Colletotrichum gloeosporioides) in Stylosanthes scabra

Abstract: Nineteen accessions of Stylosanthes scabra that had low terminal severities of anthracnose in the field were evaluated for their response in the glasshouse using four isolates representing three different races of Colletotrichum gloeosporioides. Accessions could be allocated to one of three groups: one showed a higher disease severity after inoculation with isolate UQ14 compared to the other isolates; the second showed a higher severity after inoculation with isolates WRS32 and/or WRS20 compared to isolates SR… Show more

“…Given the length of the incubation period of C. gloeosporioides on cv. Fitzroy (Chakraborty et al ., 1988), the high prediction success of series 3 models probably represents long‐term correlations within weather and may not explain a direct causal relationship between weather and anthracnose severity. Further studies are necessary to explore this.…”

“…In the susceptible cv. Fitzroy the interval from inoculation to the first sign of symptom appearance is 3·9 days (Chakraborty et al ., 1988), and another 2–3 days elapse before at least 10% of typical sporulating lesions are clearly visible. To account for the lag in symptom expression, three series of models were developed to examine the influence of weather on disease severity.…”

“…Entretanto, há patossistemas em que o PI e o PL não são componentes úteis para detectar a resistência quantitativa, como em Stylosanthes scabra Vog. -C. gloeosporioides e trigo de inverno -S. nodorum (Chakraborty et al, 1988). Se for componente importante no patossistema cebola -C. gloeosporioides, provavelmente, aumentando-se o número de acessos/cultivares testados e, ou, de repetições, diferenças quanto ao PL poderão ser detectadas.…”

“…e SCHERENK., é o principal agente causal da antracnose. Tal patógeno incita dois tipos de sintomas distintos, tipos A e B (CHAKRABORTY et al, 1988). O sintoma tipo A caracteriza-se pela ocorrência de lesões marrom-claras a cinzas e margens escuras em caules, folíolos e inflorescências.…”
