Abstract
In order to explore whether reciprocal hybridization can be used to cultivate new varieties of wild vegetable, the experiment used two ecological types (farmland ecotype and mine ecotype) of Solanum photeinocarpum as the experimental material of reciprocal hybridization, and compared the difference of qualities of F1 hybrids and parents. The results showed that the biomass, contents of vitamin C, soluble sugar, total acid, and soluble solids of leaves and stems of the F1 hybrid plants were not significantly different. But the indicators of F1 hybrid were higher than the parents. Among them, mining male × farmland female F1 hybrids has the highest leaf biomass, vitamin C content and soluble sugar content. The highest leaf biomass, vitamin C content and soluble sugar content were increased by 13.70%, 65.90% and 117.26% respectively, compared with the farmland ecotype, and increased by 14.40%, 48.89% and 54.99% respectively, compared with the mine ecotype. It indicated that reciprocal hybridization can effectively increase the biomass and the content of nutrients including vitamin C of F1 hybrids and reciprocal hybridization can be used to get new species of Solanum photeinocarpum.
