Description Peanut or groundnut (Arachis hypogaea L.) is second, behind soybean, in the
world’s legume oilseed market. In 2012, global production was 41.2metric tons
from an area of 24.7million hectares (FAOSTAT, 2014). Yield of peanut under
stressed environments is an ultimate goal of improvement for enhanced production
as it is usually susceptible to a range of abiotic and biotic stresses, such as
drought, tomato spotted wilt virus (TSWV), early leaf spot (ELS) and late leaf
spot (LLS), nematodes, rust, and aflatoxin contamination (Guo et al., 2012a).
However, cultivated peanut is an allotetraploid (2n=4x=40) with a large
genome, which greatly complicates interpretation of genomic data compared
with the diploid wild relatives (2n=2x=20) (Guo et al., 2013). It is difficult to
transfer alleles from wild species to cultivated peanuts (Simpson, 1991). For
the last ten years, extensive efforts in the area of peanut genomics have resulted
in a large number of genetic and genomic resources such as mapping populations,
expressed sequence tags (ESTs), a wide range of molecular markers,
transcriptome and proteomics (Guo et al., 2013; Katam et al., 2014; Varshney
et al., 2013). These genetic and genomic resources have been successfully used
to construct genetic maps, to identify quantitative trait loci (QTLs) of traits of

interest, and to conduct marker-assisted selection and association mapping for
peanut improvement (Pandey et al., 2014a).
