Wild Crop Relatives: Genomic and Breeding Resources

Abstract

Citrus is one of the most important fruit crops grown in the subtropical and tropical areas of the world and has great economic, health, religious, and cultural values. While there are conservation and management efforts, the lack of sufficient descriptions, specimens, and original habitats has made it difficult for the biogeographers to define precisely the centers of origin and ancestors of citrus. Understanding taxonomy, phylogenetic relationships, and genetic variability in citrus is critical for determining its origin, evolution, and efficient genetic improvement programs. Though citrus breeding is very challenging, different breeding programs throughout the world have made significant progress in the application of conventional and modern approaches for genetic improvement and cultivar development. The recent knowledge and establishment of an array of genomics and bioinformatics tools have provided efficient strategies to identify, tag, and clone many economically important genes. Progress toward these efforts in citrus has been discussed.
