Abstract
A field experiment was conducted at dryland farm, S.V. Agricultural College, Tirupati to evaluate sesame germplasm against phyllody disease during two seasons i.e., kharif, 2019 and late rabi, 2019-20. Hundred and seven sesame genotypes were screened in a randomized block design for resistance to phyllody. The per cent phyllody incidence ranged from 6.25 (IC 203871) to 86.90 per cent (YLM 66) and 2.09 (IC 203871) to 56.73 (Gowri) during kharif, 2019 and late rabi, 2019-20, respectively. The pooled results of two seasons indicated that out of 107 sesame genotypes screened for resistance to phyllody, the phyllody incidence was in the range of 4.17 to 71.64 per cent and two genotypes viz., IC 203871 (4.17) and EC 377002-2 (4.41) were found to be resistant to phyllody.
