Stability pattern and simultaneous selection for the stable essential oil-yielding genotypes of basil

Basil leaves are used to make a tea that promises to assist with vomiting, rheumatic pain, and loose motions. It includes a high concentration of antioxidants, which may increase longevity and health. The current study aims to assess the consistency, stability, and recommendations for producing essential oils from commercial genotypes and cultivars. To investigate genotype stability, field experiments were conducted in a semi-arid tropical climate in an RBD and replicated three times over three years in 2017, 2018, and 2019, at the CIMAP, RC, Hyderabad, south India. Each of the thirteen economic variables exhibited substantial diversity. In a three-year experiment, the stability of 20 basil genotypes was studied. There have been very few studies on the genotype and environmental interactions, stability, and diversity of basil. Nonetheless, no simultaneous assessments, stability, or reliability analyses have been performed in a multi-environment essential oil yield study on basil. According to the AMMI model, genotypes OC-6 and 8 for oil yield and OC-6 and 10 for linalool (%) were the most adaptable and stable varieties because they could withstand a wide range of environmental conditions. This leads to the conclusion that the most stable genotypes for linalool content (%) and essential oil production are OC-6, OC-8, and OC-10, all of which provide excellent yields. As a result, it is suggested that these genotypes and cultivars be commercialized.
