A field screening trial was laid out with 20 genotypes of sesame along with one susceptible check YLM-66 against the leafhopper in the Agriculture Research station, Utukur during kharif 2018 and 2019 in three different dates of sowing (I&II FN of July and I FN of August). Pooled data analysis of two years revealed that, highest leaf hopper and phyllody incidence were observed in first date of sowing only (I FN of July). Among the entries in first date of sowing, leaf hopper population ranged from 0.50 to 5.70 per plant, lowest leaf hopper per plant (0.50) was observed in entry UTS-59 followed by IC-205556 (0.90) and UTS-208 (1.60) and highest in Gowri (5.70). The per cent phyllody disease incidence ranged from 1.25 to 30.38, lowest phyllody incidence (1.25%) was recorded in UTS-59, followed by IC-205556 (4.90%) and UTS-208(5.80%) where as highest phyllody disease was recorded in Pragathi (30.38). The leaf hoppers were collected and sent for identification to Division of entomology, IARI, New Delhi and identified as Orosius albicinctus
Screening, sesame entries, leaf hopper, Southern zone
The entries UTS-59, IC-205556, UTS-208 have recorded lowest leaf hopper population per plant and phyllody disease incidence. These three entries can be promoted for further studies like identification of physical and biochemical parameters contributing resistance against leaf hopper and phyllody and also they can be used in breeding programme to develop phyllody resistant varieties
