Determination of seed yield, quality and fixed oil components of different basil (Ocimum basilicum L.) genotypes: Evaluation of fatty acid profile by PCA biplot analysis

Abstract

Basil (Ocimum basilicum L.) plants are generally grown for different properties and produce seed with a considerable amount at the end of the growing season. This study was carried out to determine the seed yield, quality and fixed oil components of eight different basil (B) genotypes with purple (PB) and green (GB) leaf color obtained from different countries. In other words, seed yield and quality, fixed oil components, the seed yield, 1000 seed weight, oil content, oil yield, crude protein, ash, linoleic acid, linolenic acid, oleic acid, palmitic acid, stearic acid, hexadecatrienoic acid properties, ethyl linolate and trace oil contents were investigated. Seed yield, 1000 seeds weight and oil yield were significant statistically among the genotypes. While the best result in terms of seed and oil yield was obtained from GB1, the highest 1000 seeds weight was recorded in GB4. Palmitic acid and trace oil contents of genotypes were significant statistically. The highest palmitic acid content was detected in GB2, whereas the maximum trace oil contents were obtained from GB5. In results of principal components analysis (PCA) purple and green basil types demonstrated different features in terms of fixed oil components. GB2, GB4 and GB5 basil genotypes which have green leaf types were superior according to the PCA. GB2 genotype obtained from Hungary was the better in terms of seed yield and fixed oil components among the purple and green basil genotypes used in this research.
