GENETIC VARIABILITY AND VIRAL DISEASE ASSESSMENTS IN SOLANUM SPP.
Garden egg (Solanum gilo) is highly adaptable as a potential crop in the sub-Saharan African tropical region for food security purposes. Garden egg germplasm seed evaluation and characterization was carried out on the nationwide seed collection to expand the National Horticultural Research Institute (NIHORT) genetic base for Solanum. The field layout was a randomized complete block design with five replications. The treatments included Solanum gilo, S. macrocarpon and the local garden egg. There was a significantly phenotypic difference in the S. gilo variety. This difference was observed in the plant spinyness as well as in the deep purple coloration of the stem, leaf and petiole. Our observations revealed significant tolerance to Veinal mottle mosaic virus (VMMV) in the purple colored cultivars compared to the green garden egg cultivar up to harvesting. We propose that inducement of purplish coloration in garden egg might improve tolerance to VMMV and thereby increase yield through further breeding programs.
