Abstract

Based on the systematic study of the nature of symptoms and extent of damage, a rating scale of 1 (healthy plant) to 9 (deadheart) was developed to allow the screening of maize genotypes for resistance to the pink stemborer, Sesamia inferens (Walker). The maize plants were separated into three distinct groups, namely least susceptible (1–3 score), moderately susceptible (4–6) and highly susceptible (7–9).

Résumé

En se basant sur l'étude systématique de la nature des symptômes et de l'étendue des dégàts, une échelle de classement comprise entre 1 (plante saine) et 9 (coeur mort) a été développée pour permettre un criblage des génotypes de maïs contre le foreur rose, Sesamia inferens (Walker). Les plants de maïs ont été séparés en trois groupes, peu attaqués (échelle 1–3), modérément attaqués (échelle 4–6) et fortement attaqués (échelle 7–9).
