Abstract

Abstract: Fruit carotenoid levels in tomato could be elevated significantly by high-pigment genes hp1 and hp2.They are valuable for quality breeding program targeting increasing lycopene content in tomato fruit.Based on their point mutations,specific molecular markers correspondent to them have successfully developed.Then,hp1 and hp2 could be accurately tagged by these markers,as the markers are in fact amplificated products of gene parts.In F_{2_{population the segregation of molecular markers were in consistent with expected ratio of two independent genes.Lines with both hp1 and hp2 have been developed based on the molecular markers.}}
