Cultivated sesame (Sesamum indicum L., 2n = 2x = 26), one of the world’s most important and ancient oilseed crop is cultivated in subtropical and tropical regions of the world, including India. Waterlogging is one of the adverse factors constraining sesame production (Li et al., 2017). Loss of sesame seed yields due to waterlogging ranges from 30 % to 100 % worldwide (Li et al., 2017) and 15 % to 80 % in India (Sreepriya and Girija, 2020), depending on the duration of waterlogging, growth stage of the crop, and type of soil (Sarkar et al., 2016). Therefore, identification of waterlogging tolerant sesame lines is crucial to waterlogging tolerant sesame breeding program. With this background, an experiment was conducted to identify waterlogging stress tolerant sesame lines.
METHODOLOGY
An experiment was conducted during Rabi season of 2020 at the research farm of ICAR-Indian Institute of Oilseeds Research, Hyderabad, India. A panel of 120 sesame lines were sown in 3 metre rows following alpha lattice design with triplication. A spacing of 10 cm plan-to-plant and 45 cm row-to-row was followed with recommended package of practice. The crop was exposed to 10 days waterlogging stress at the seedling establishment stage, followed by six days during flowering stage. Data on seed yield and related traits were recorded from five random individual plants and the statistical analyses were performed with AGRICOLA package in R software.
RESULTS AND DISCUSSIONS
A studied set of 120 sesame genotypes were subjected analysis of variance (ANOVA) and genetic variability and results are summarized in tables 1 and 2 respectively. Sesame genotypes varied significantly for most of the traits (Table 1), and most of the traits showed statistical significance p
