SUSCEPTIBILITY OF DIFFERENT GARLIC (Allium sativum L.) TYPES TO Sclerotium cepivorum Berk.

Abstract

The objective of this study was to confirm field observations on differences in susceptibility to white rot (Sclerotium cepivorum Berk.) shown by white, red and pink types of garlic cultivars planted in Mexico. Pink cultivars of garlic were the most susceptible followed by red and white cultivars. White rot induced the higher yield reductions on the pink cultivars (75 to 99 %), red varieties 65 to 90 %, and white cultivars 23 to 55 %. The white cultivars Perla and Blanco de Cortazar together with ‘Massine’ and ‘Taiwan’ types of red and pink cultivars, respectively, showed the lowest susceptibility to S. cepivorum.
