Abstract

Aim: The aim of the study was to evaluate the stability, reliability and suggestions for making essential oils from commercial basil genotypes.

Materials and Methods: To examine the stability of genotypes, field experiments were conducted in three years and twelve distinct basil cultivars were examined in order to identify those that consistently produced high levels of linalool oil under various settings and seasons.. The RBD two factor design and Principal component analysis (PCA) were performed to explore the interrelationships among traits under different environments.

Results: Results revealed that the genotypes for essential oil yield and O-2, O-6, and O-10 for linalool content (%) had the most adaptability and were the most stable variety due to their capacity to endure a broad range of environmental conditions over time. Given this, it can be said that the genotypes/varieties O-6, OC-8, and OC-10 were the most stable and had good yield performance for linalool content (%) and essential oil production. PCA revealed significant genetic variation in this basil sample as well, with PC1 through PC12 exhibiting high variable data values for each PC. The PCA also revealed the considerable genetic variety in this set of basil materials. For example, PC1 to PC11 showed extremely varying data values for each PC. Among the twelve characteristics of the basil, the corresponding greatest eigenvalues were 5.121 and the percentage of variances was 42.671.

Conclusion: It was concluded that genotypes O-6, OC-8, and OC-10 and variability can be efficiently used for additional genetic progress through heterosis breeding.
