Field evaluation of sesame lines against phyllody

Abstract

In the integrated management of phyllody disease of sesame, host plant resistance plays an important role. Use of resistant genotype is one of the most viable options for the management of the sesame phyllody. Screening of material is essential to identify the real source of resistance. Sesame lines were screened against sesame phyllody during kharif 2015. In the IVT entries screened against sesame phyllody the disease incidence ranged from 4.61 to 28.49 per cent, while in AVT entries it ranged from 13.95 to 30.53 per cent. In the germplasm lines (25) the incidence of phyllody ranged from 4.60 to 28.19 per cent. Among the sesame lines screened against phyllody disease under field conditions, three genotypes viz., KAU-05-2-12, PC-14-2 and Kanakapura local showed resistant reaction, 27 lines viz., DS-28, RT-363, CUHY-57, AT-255, DS-23, DS-10, NIC-16236, AKT 101, RT-54, Amrit, AKT-64, RT-125, TMV-3, TKG 306, ST-9-2, ES-48, Chandana, ES- 8779-4, IS 294, E-8, DS-1, GT-1, DS-9, K-15284, RT-11, EC-303419 and Gulbarga showed moderately resistant reaction, 13 lines viz., JCS-2464, AT-249, PC-14-1, TKG-22, AT-282, GT-10, DS-19, CUMS-17, JLS-301-24, AT-231, DS-5, Local variety (black) and DSS-9 showed susceptible reaction.
