Assessment of germplasms for their relative susceptibility against thrips (Scirtothrips dorsalis Hood) infesting chilli [Capsicum annum L.]

Abstract

Investigations were carried out on “Assessment of germplasms for their relative susceptibility against thrips (Scirtothrips dorsalis Hood) infesting chilli [Capsicum annum L.]” at Instructional Farm, ASPEE College of Horticulture and Forestry, Regional Horticultural Research Station, Navsari Agricultural University, Navsari during 2017-18 and 2018-19. The results revealed that, maximum thrips population was found in GVC-121 (3.01/3 leaves) whereas, it remained maximum thrips population in GCH-3 (6.95/3 leaves). Likewise, maximum fruit yield was obtained in GAVC hybrid-1 (50.60 q/ha) it was minimum in GCH-3 (35.11 q/ha). Overall, GVC-121 and GVC-111 were grouped under highly resistant category with respect to susceptibility to thrips population. Similarly, GAVC hybrid-1 and GVC-101 were grouped in resistant category against thrips population. GAVC-112 and AVNPC-131 were grouped in the susceptible category against thrips population. Lastly, GCH-1 and GCH-3 were grouped in highly susceptible category against thrips population.
