“…The combination of both qualitative and quantitative characters has earlier been realized through interspecific hybrids of aromatic grasses (Cymbopogon group), leading to development of the hybrid clones, namely CKP-25-i.e., C. khasianus x C. pendulus, and Jamarosa i.e., C. jwaruncusha x C. confertiflorus [7]. More recently, Srivastava et al [21] has reported the occurrence of huge variation in qualitative profile in the essential oil of Ocimum basilicum differentially enriched either for methyl chavicol, methyl euginol, linalool, methyl cinnamate, promising the development of diverse varieties for commercial cultivation. Further, to fix this natural variability and to enhance the growing potential of such variant genotypes from annual to perennial, interspecific hybrids are developed between O. basilicum after inter-crossing this with cold tolerant O. kilimandscharicum to change it to evergreen genotype [2].…”

Whereas the splitting of ancestral lineage into daughter species remains a common course of speciation, but hybridizing the two related species to give rise to a third independent lineage could be a powerful tool to hybrid speciation. The latter could give way to new plant type/s featuring novel combination for physiological, developmental, and metabolic pathways. Pre-selection of progenitor parental genotypes could enable realization of hybrid lineages with predictable features to a large extent. At the same time such derived lineages shall ensure hybrid fixity through vegetative propagation, but could offer opportunity of seed cultivation through ploidy mediation for fixation and/ or variation through meiotic segregation for selection of novel types. Experimental manoeuvring imitating homoploid speciation or somatic variation could be the other means to release de novo variation. In view of above, a prospective outline is discussed towards qualitative breeding for secondary metabolites.

Basil (Ocimum basilicum L.) is found worldwide and is used in the food, pharmaceutical, and cosmetic industries; however, the nutritional and functional properties of the seeds are scarcely known. Basil seeds contain high concentrations of proteins (11.4–22.5 g/100 g), with all the essential amino acids except S-containing types and tryptophan; dietary fiber (soluble and insoluble) ranging from 7.11 to 26.2 g/100 g lipids, with linoleic (12–85.6 g/100 g) and linolenic fatty acids (0.3–75 g/100 g) comprising the highest proportions; minerals, such as calcium, potassium, and magnesium, in high amounts; and phenolic compounds, such as orientine, vicentine, and rosmarinic acid. In addition, their consumption is associated with several health benefits, such as the prevention of type-2 diabetes, cardio-protection, antioxidant and antimicrobial effects, and anti-inflammatory, antiulcer, anticoagulant, and anti-depressant properties, among others. The focus of this systematic review was to study the current state of knowledge and explore the enormous potential of basil seeds as a functional food and source of functional ingredients to be incorporated into foods.

“…Several aromatic plants have been reported to produce ME, including basils of the genus Ocimum (Lamiaceae family), which are widespread in Asia, Africa, Central America and South America (Pandey et al, 2014;Srivastava et al, 2018). Some of these basil plants include O. tenuiflorum L., O. basilicum L., O. gratissimum L., O. kilimandscharicum Gürke, and O. africanum Sims, which are annul and perennial herbs cultivated for many uses, including cooking, traditional medicine and other (economic) benefits.…”

IntroductionHorticulture is an important sub-sector for many African countries. Tephritid fruit flies continue to cause serious direct and indirect damage to the sub-sector. The male annihilation technique (MAT) using methyl eugenol (ME) is among the most revered techniques in fruit fly management. However, ME-based lures are only available to some farmers in Africa. Several basils of the genus Ocimum produce ME.MethodsIn laboratory experiments, we used a dual choice olfactometer to assess the attraction of adult oriental fruit fly Bactrocera dorsalis to intact plants, 100 µL commercial methyl eugenol (ME) (positive control), 10 mg/mL of O. tenuiflorum aqueous extract (Otae), and a negative control (blank). Large arena experiments were conducted to compare the responses of four fruit fly species of economic importance in Africa to Otae-baited traps.ResultsIn dual choice olfactometer assay, more B. dorsalis males (78.6%) than females (23.8%) were attracted to Otae. Most B. dorsalis males were attracted to the positive control (90.5%) and 10 mg/mL Otae (88.5%) compared to the whole plant (84.0%). In large arena experiments, Otae attracted the most B. dorsalis males (47.7%), followed by Zeugodacus cucurbitae males (25.1%), while males of Ceratitis species were the least attracted. The analysis of headspace volatiles from aerial plants, Otae and essential oil using gas chromatography-mass spectrometry detected 97 compounds. The intact plant without flowers, intact plant with flowers, Otae, and the O. tenuiflorum essential oil contributed 76, 62, 33 and 28 compounds, respectively. ME comprised the top three most abundant compounds, especially in the essential oil.DiscussionOur study confirms the potential of O. tenuiflorum as a source of ME for tephritid fruit fly integrated management in Africa. Otae, a readily available alternative to commercial ME, can be used to develop fruit fly-baited traps, particularly for smallholder farmers.
