An International Reference Consensus Genetic Map with 897 Marker Loci Based on 11 Mapping Populations for Tetraploid Groundnut (Arachis hypogaea L.)

Abstract: Only a few genetic maps based on recombinant inbred line (RIL) and backcross (BC) populations have been developed for tetraploid groundnut. The marker density, however, is not very satisfactory especially in the context of large genome size (2800 Mb/1C) and 20 linkage groups (LGs). Therefore, using marker segregation data for 10 RILs and one BC population from the international groundnut community, with the help of common markers across different populations, a reference consensus genetic map has been develope… Show more

“…Progeny are vigorous, phenotypically normal and fertile and showed lower segregation distortion 16,17 than has been observed for some populations derived from A. hypogaea intraspecific crosses [18][19][20][21] . Therefore, as a first step to characterizing the genome of cultivated peanut, we sequenced and analyzed the genomes of the two diploid ancestors of cultivated peanut.…”

“…Nowadays, hundreds or thousands of widely distributed SNPs and their positions in the genome (provide the reference genome is accessible) can be identified in a relatively short period of time and at a low cost. Thereby, in recent years, the number of molecular markers and, therefore, map resolutions have increased, which ultimately leads to the reduction of QTL interval lengths to a few cM (Gautami et al, 2012;Stephens et al, 2014;Soto et al, 2015).…”

“…More interestingly, this reference consensus genetic map was divided into 203 sets of 20 cM bins, each which carry one to 20 loci with an average of four marker loci per bin. Furthermore, soon after the first dense consensus map published by Gautami et al (2012b), another joint international research effort has resulted in a much improved consensus genetic map based on 16 mapping populations. The mapping information from five new genetic maps were utilized for improvement of the earlier consensus map from 897 marker loci to 3693 marker loci spanning 2651 cM of the genome and 20 linkage groups (Shirasawa et al, 2013).…”
