Genetic diversity in a collection of borage (Borago officinalis) germplasm

Abstract

The common borage, Borago officinalis L., is of Euro-Mediterranean origin, but is found extensively in the wild. It is also cultivated as a garden plant, crop vegetable, or pharmaceutical herb. Analysis of random amplified polymorphic DNAs (RAPDs) revealed high levels of genetic diversity among 10 borage wild accessions and seven cultivars, which included five white-flowered selections grown in northern Spain for petiole production, and two blue-flowered lines used medicinally. These latter two cultivars and populations, sampled far from the original habitat of the species, were closely related to wild borage populations from northern Europe. The two medicinal cultivars did not differ from each other, while those used for petiole production differed significantly from their Spanish wild relatives. Differences among the 17 populations accounted for 41.4% of the total genetic variability; this value increased to 50.8% when only the 10 wild populations were considered. Population differentiation and within-population variability are discussed in relation to mating system, selection, and conservation practices.

Evaluation of Borage (Borago officinalis L.) Genotypes for Nutraceutical Value Based on Leaves Fatty Acids Composition

“…When leaf blades and petioles were analyzed separately, these results were reinforced. Sales et al [43], who studied some of the genotypes used in this work, also described a similar trend in borage germplasm after using molecular tools.…”

Production of doubled haploid plants from anther cultures of borage (Borago officinalis L.) by the application of chemical and physical stress

“…Unfortunately, to the best of our knowledge there are no SSR available for borage. The only available molecular markers are AFLPs (De Lisi et al 2014) and RAPDs (Sales et al 2008).…”
