Evaluacion de Germoplasma de Pimenton y Aji Picante a Meloidogyne incognita en Panama

Abstract

Eighteen cultivars and breeding lines of bell (Capsicum annum) and chile (C. frutescens) peppers from Costa Rica and Panama were tested for their reaction to Meloidogyne incognita. Many of these materials already have resistance or tolerance to bacterial wilt caused by Pseudomonas solanacearum and Xanthomonas spp. All materials tested were susceptible to the root-knot nematode. Gall indices and final nematode populations were high in the majority of the cases. However, the breeding lines P-63, P-66, and 10871 developed a significantly larger root mass with extensive ramification and smaller galls than the rest, suggesting that these materials might be tolerant. Additional evaluation under field condition and in bacteria infested soil is required.
