Progress in the Molecular Biology of Solanum peruvianum

Solanum peruvianum is wild species related to S.lycopersicum,and possesses potential value for genetic improvement of tomato.In order to effectively utilize S.peruvianum and provide available information for tomato genetic improvement,we reviewed origin,taxonomy,biology character,and molecular biology of S.peruvianum,as well as progress in overcoming distant hybridization barriers between S.lycopersicum and S.peruvianum.The strategies of using S.peruvianum for tomato improvement were discussed in this paper.
