Abstract
One hundred and twelve accessions of sunflower (Helianthus annuus L.) were screened under field conditions in two seasons (Rabi 2016 and Kharif 2017) at Sambavar vadakarai and Udappankulam villages of Tirunelveli district of Tamilnadu for their resistance against leaf hopper (Amrasca biguttula biguttula Ishida). Observations on the number of nymphs/adults per plant at weekly interval revealed promising accessions against the study insect. In the first season, four accessions viz., KBSH 1, IHT 751, GK 2002, and AHT 14 harboured the least population whereas in the second season, KBSH 1, IHT 751 proved to be promising. In both seasons, the mean insect population showed significant difference with passage of time.
