Pathologic Reaction of Garden Pea (Pisum sativum L) Cultivars/ Advanced Breeding Lines to Fusarium oxysporum f sp pisi (Linford) Synder and Hansen

Abstract

Pot experiments were carried out under greenhouse conditions to evaluate the resistance of eight garden pea cultivars/ advanced breeding lines to Fusarium oxysporum f. sp. pisi (FOP). The effect of FOP inoculation on plant height, fresh and dry weights of shoots and roots and number and weight of pods were assessed 60 days after planting. Stems were examined for necrotic lesion scores.

Based on the necrotic lesion score and pathologic reaction of plants at 60 days after inoculation, Betag, CGP 110 and 154 were rated as resistant; CGP 59, 11, and 34 as intermediate; and CLG and CGP 13 as susceptible to Fusarium wilt.
