Abstract

An investigation was undertaken to study the “Estimation of Stability Parameter for Yield and Yield Contributing Characters in Sesame (Sesamum indicum L.)” to gather information on different variability parameters, genotype × environment interactions and stability parameters. The experimental material comprised of 60 different Varieties of sesamum. The experiment was conducted in Randomized Complete Block Design with three replications at Project Coordinating Unit (Sesame and Niger) Research Farm, JNKVV, Jabalpur during Kharif 2016 (E1), Summer 2017 (E2), Kharif 2017 (E3) and Summer 2018 (E4). Observations on five randomly selected plants per genotype per replication in each environment were recorded for days to flower initiation, days to 50% flowering, days to maturity, flower petal colour, flower petal hairiness, plant branching pattern, plant branching habit, stem hairiness, leaf lobes, leaf size, leaf serration of margin, capsule shape, capsule arrangement, capsule hairiness,

Keywords

Sesame, stability, yield components, Genotype × Environment interaction.

Conclusion

Overall results of stability analysis indicates that genotype YLM-11 was found as stable genotypes which exhibited stable performances for more than two characters, while genotypes N-32, SAVITRI, RAMA, RAJESHWARI, RT-351 and GT-1 exhibited above average stability for yield and yield components and therefore, these genotypes were specifically adapted to unfavorable environmental conditions.
