Abstract

A study was conducted to identify Botrytis spp. isolated from bulb onion, green onions, garlic and garlic chives grown in Hubei Province of China. Based on colony morphology and conidial characteristics, 367 strains of Botrytis spp. were identified as five distinct species, namely B. cinerea, B. squamosa, B. porri, B. byssoidea and an undescribed species of Botrytis (Botrytis sp.), which accounted for 64.3, 29.9, 3.3, 0.3, and 2.2%, respectively. Botrytis sp. is herein described as a new species, Botrytis sinoallii sp. nov., which is characterized by production of numerous small sclerotia on potato dextrose agar. Phylogenetic analysis using partial sequences of three nuclear genes (G3PDH, HSP60 and RPB2) showed that B. sinoallii forms a unique lineage, which is closely related to the lineage of B. squamosa, a well-known species on Allium crops, but distantly related to lineages of the other species of Botrytis on Allium crops, including B. cinerea, B. porri, B. aclada, B. allii, B. byssoidea, B. globosa and B. sphaerosperma. Results of inoculation tests showed that B. sinoallii is a novel agent causing leaf blight of green onion, garlic and garlic chives. Potential impact of B. sinoallii on production of Allium crops in China is discussed.
