Research advances of genetics and breeding in Caragana species.

Recent research advances on genetics and breeding in Caragana species are reviewed in this article, including genetic variation and diversity,gene identification and cloning,genetic improvement and breeding. The results show that the researches on Caragana mainly focus on few species such as Caragana korshinskii, C. microphylla and C. intermedia. There are major researches on genetic diversity,gene cloning and function but slow development on traditional breeding. At present Caragana plants mainly rely on seeds for their regeneration and asexual propagation is still in the stage of research. The researches on structure and function of resistance gene have the important value to cultivate and select the species with high stress resistance. The researches on oil related gene are the basic for bio-diesel fuel development. Fine breeding and crossbreeding will be the research emphases for the future work.
