- Shirasawa et al. 2013 developed a high-density integrated consensus map using three RILs. This high density map along with 13 published maps were integrated into a consensus map spanning 2,651 cM with 3,693 marker loci which was anchored to 20 consensus LGs corresponding to the A and B genomes.
- Gautami et al. 2012 developed International reference consensus genetic map based on 11 mapping populations (10 RILs and one BC population) for tetraploid groundnut. Consensus genetic map contains 897 marker loci including 895 simple sequence repeat (SSR) and 2 cleaved amplified polymorphic sequence (CAPS) loci distributed on 20 LGs spanning a map distance of 3, 863.6 cM with an average map density of 4.4 cM.

Gautami B et.al. 2012 used two new recombinant inbred line (RIL) mapping populations, namely ICGS 76 × CSMG 84-1 (RIL-2) and ICGS 44 × ICGS 76 (RIL-3), for screening of 3,215 SSR markers on the parental genotypes of these populations, two new genetic maps were developed with 119 (RIL-2) and 82 (RIL-3) SSR loci. Together with these maps and the reference map with 191 SSR loci based on TAG 24 × ICGV 86031 (RIL-1), constructed a consensus map with 293 SSR loci distributed over 20 linkage groups, spanning 2,840.8 cM.
- Nagy et al. 2012 developed high-density genetic map of Arachis duranensis. In total, 1,536 SNP markers were developed from genomic sequences representing conserved legume orthologs and ESTs. A total of 1,054 SNP markers could be mapped out of total 1,536 SNP markers used in addition to 598 EST-SSR markers identified in A. hypogaea, 37 disease resistance gene candidates (RGC) and 35 other previously published markers. This resulted in development of a high density map that contains 1,724 markers spanning 1081.3 cM over 10 linkage groups.
- Sujay V et.al. 2012 generated linkage map using 209 loci resulted in the mapping of 188 and 181 loci in RIL-4 and RIL-5 respectively. Using 143 markers common to the two maps, a consensus map with 225 SSR loci and total map distance of 1,152.9 cM was developed.

Ravi et.al. 2011 developed a comprehensive and refined genetic linkage map containing 191 SSR loci based on a single mapping population (TAG 24 x ICGV 86031) and covers 1,785.4 cM of total map distance.
- Hong et al. 2010 developed composite linkage map for the cultivated peanut from three individual mapping populations with 175 SSR markers in 22 composite linkage groups. Three recombinant inbred lines (RILs) populations were developed with one common female parental line Yueyou 13 which along with 3 male parents was used for polymorphism screening using 1044 SSR markers. Three individual linkage maps were constructed and a composite map based on 93 common loci were created using JoinMap. The composite linkage maps consist of 175 SSR markers representing the 20 chromosomes ofA. hypogaea spanning . The total composite map length is 885.4 cM, with an average marker density of 5.8 cM.
- Foncéka et al. 2009 developed genetic map developed for synteny analysis of the A and B genomes and the comparison of diploid and tetraploid maps. Two hundred ninety eight (298) loci were mapped in 21 linkage groups (LGs), spanning a total map distance of 1843.7 cM with an average distance of 6.1 cM between adjacent markers.
- Varshney et al. 2009 reported first SSR-based genetic linkage map for cultivated groundnut. In total 144 polymorphic markers were identified after screening 1,145 SSR markers on two genotypes, TAG 24 and ICGV 86031 that are parents of a recombinant inbred line mapping population. In total, 135 loci could be mapped into 22 linkage groups.
- Moretzsohn et al. 2005 reported microsatellite-based, gene-rich linkage map for the AA genome ofArachis using an F2 population obtained from a cross between A. duranensisand and A. stenosperma. In total, 204 markers including 170 co-dominant and 34 dominant markers were found polymorphic for cultivated peanut after screening 433 markers. Linkage map developed spans 1,230.89 cM of total map distance, with an average distance of 7.24 cM between markers across 11 linkage groups.
