Description
Summary:The relationship between genotype and season significantly hinders the development of stable genotype selection and improved genotypes for senna breeding programs. This study aimed to assess stable, high-yielding senna genotypes under South Indian conditions. Twenty-five different senna genotypes were tested for yield stability using a randomized, completely-block design. The additive main effects and multiplicative interaction (AMMI) model was used to investigate the relationships between genotype (G), environment (E), and genotype × environment. Based on the findings, the three genotypes—GEN 1, GEN 9, and GEN 18—might be recommended for large-scale production. Stable and high-yielding genotypes should be the main genetic resources used in senna-based cropping season breeding programs. [Display omitted]
