abstract: Recombination hot spots (RHP), caused by meiosis, are considered to play crucial roles in
improvement and domestication of crop. Cultivated peanut is one of the most important rich-source of
oil and protein crops. However, no direct scale of recombination events and RHP have been estimated
for peanut. To examine the scale of recombination events and RHP in peanut, a RIL population with
200 lines and a natural population with 49 cultivars were evaluated. The precise integrated map
comprises 4837 SLAF markers with genetic length of 2915.46 cM and density of 1.66 markers per cM
in whole genome. An average of 30.0 crossover (2.06 cMMb−
1) events was detected per RIL plant. The
crossover events (CE) showed uneven distribution among B sub-genome (2.32) and A sub-genome
(1.85). There were 4.34% and 7.86% of the genome contained large numbers of CE (> 50 cMMb−
1)
along chromosomes in F6
and natural population, respectively. High density of CE regions called RHP,
showed negative relationship to marker haplotypes conservative region but positive to heatmap of
recombination. The genes located within the RHP regions by GO categories showed the responding of
environmental stimuli, which suggested that recombination plays a crucial role in peanut adaptation
to changing environments
