Screening, Morphological and Biochemical Basis of Resistance against Leaf Curl Disease in Sunflower Coordinated Entries

K. Venkataramanamma, B. V. Ravi Prakash Reddy, K. Prabhakar, S. Ramadevi, R. Naseeruddin & T. Raghavendra · Journal of Advances in Biology & Biotechnology · 2026

Background: Sunflower leaf curl disease, caused by begomovirus and transmitted by whitefly (Bemisia tabaci), is a major constraint in sunflower production, leading to significant yield and oil losses. Identifying resistant genotypes and understanding associated resistance mechani...
