Abstract

Cacao (Theobroma cacao) is a tropical plant that is grown throughout India. Cacao pods exhibiting chocolate brown patched symptoms were collected. The organism was isolated and cultured on V8 Agar from the diseased samples. The pathogenicity was proved on Cacao pods by inoculating mycelium of the organism and Koch’s postulates were proved by re-isolating the pathogen. The pathogen was identified as Phytophthora tropicalis based on cultural and morphological characters, followed by molecular investigations (ITS and COX1). This is the first report of Phytophthora tropicalis causing black pod of Cacao in India.

热带疫霉菌引起印度可可黑荚病的首次报告

可可（Theobroma Cacao）是一种热带植物，生长在印度各地。采集表现出巧克力褐色补丁症状的可可荚。从患病样品中分离该生物体并在V8琼脂上培养。通过接种该生物的菌丝体证明了其在可可荚上的致病性，并通过重新分离病原体证明了Koch的假设。根据病原菌的培养和形态特征，通过分子生物学研究（ITS和COX1），鉴定为热带疫霉菌。这是印度首次报道热带疫霉菌引起可可黑荚病。
