Generation of a 345K sugarcane SNP chip* [Full subscriber]

Abstract DNA markers can enhance rates of genetic gain in breeding programs and are currently being applied in many animal and crop species. The very large sugarcane genome means that many current ‘best bet’ markers associated with agronomic traits of interest are probably not in very close linkage with underlying causal genes. This will limit gains from future applications of markers in sugarcane breeding. The development of single nucleotide polymorphism markers (SNPs) in sugarcane can overcome the current limitations as large numbers throughout the genome can be easily screened across many genotypes. To generate a SNP chip for sugarcane with…
