Description - Groundnut Interspecific chromosome segment substitution line (CSSL) population


Speciation superimposed with domestication has contributed to the narrow the genetic basis of cultivated peanut and subsequent lack of genetic variation for important traits. Wild relatives of peanut are an important source of valuable diversity for many important traits such as pests and diseases resistance, tolerance to abiotic stress as well as nutritional value. This chromosome segment substitution line (CSSL)  library represents the entire wild species genome in a set of lines each of which carries one or few wild donor segments in the genetic background of a cultivated species and provide starting points for breeding and for mapping genes underlying QTLs.
