A study involving eight sesame genotypes conducted during 2018-2019 at the Regional Agricultural Research Station, Tirupathi with an objective of identifying climate resilient Sesame genotypes suitable for both Kharif and rabi seasons in southern region of Andhra Pradesh indicated the existence of differential response of genotypes for seed yield and yield components except for number of branches pert plant in both the seasons. Combined analysis also revealed that the genotypes differed significantly for all the characters except for branches per plant. The component of variation due to seasons was significant for all the characters except for days to maturity and thousand seed weight. The genotype x seasons interaction was non significant for number of branches per plant indicating the less influence of environment on the expression of the character. Among the sesame genotypes studied YLM 136 was found to be early in flowering and maturity. Plant height was more in rabi season compared to Kharif. Similar trend was recorded for number of capsules per plant. The genotypes viz., YLM 136 and YLM 139 have recorded more number of capsules per plant in both the seasons. All the genotypes recorded higher mean values for Specific Chlorophyll meter readings over the check YLM 66 in both the seasons. Hundred seed weight was found higher in rabi season compared to Kharif. Three genotypes viz., YLM 136, YLM 142 AND YLM 147 have registered higher mean values for seed weight over the seasons. Mean seed yield was found to be higher in rabi over Kharif season. All the genotypes have recorded higher seed yield over the check YLM 66 in Kharif while YLM 136, YLM 142, YLM 146 and YLM 147 registered higher seed yield during rabi over YLM66 .Based on seed yield and yield components and two seasons YLM 136 and YLM 142 were found to be superior to the check YLM 66 for seed yield. Theses genotypes may be recommended for commercial cultivation in Southern region of Andhra Pradesh after extensive testing under on – farm testing / adaptive minikit testing.
