Regeneration and Characterization of Plants Derived from Asymmetric Protoplast Fusion in Citrus

LIU Ji-Hong, DENG Xiu-Xin   

Abstract: RFLP (restriction fragment length polymorphism) was employed to analyze cytoplasmic genome of diploid somatic hybrid plant, morphologically similar to rough lemon which was leaf parent, that was produced via protoplast fusion between rough lemon (Citrus jambhiri Lush) and Hamlin sweet orange (C. sinensis Osb.), the embryogenic parent. Three enzyme-mitocondrial probe combinations and one enzyme-chloroplast probe combination demonstrated that the plant had identical band profiles to Hamlin sweet orange as far as mtDNA and cpDNA were concerned.

Key words: citrus, hybrid, RFLP, mitocondrial genome
