Abstract

Prevalence of Curvularia species associated with sorghum (Sorghum vulgare) seed samples collected from eight different locations of Marathwada region (viz., Omerga, Osmanabad, Latur, Beed, Jalna, Nanded, Parbhani and Aurangabad) was recorded. During seed health testing, 19 Curvularia species (C. clavata, C. cymbopogonis, C. eragrostidis, C. geniculata, C. inaequalis, C. intermedia, C. ischami, C. lunata, C. oryzae, C. ovoidea, C. pallescens, C. penniseti, C. robusta, C. senegalensis, C. siddiquii, C. sorghina, C. trifolii, C. tuberculata and C. verruculosa) were detected on the infected sorghum seeds. Seed infection of C. lunata was higher (39%) than the other species (11 to 34%) across the eight locations of Marathwada region. Among these Curvularia species, highest seed germination loss was recorded in C. ischami, while the least in C. clavata. Seed germination loss due to different Curvularia species ranged from 24.4 to 25.9%.
