In genomics era, genetic assisted breeding is more effective tool, which improves the crops cultivation from different environmental factors and prevent from revenue loss. Cross breeding of different phonotypes is resulted with new cultivars by the DNA recombination. Those, Cultivars are evolved with low levels of genetic diversity in specific genome loci with high recombination rate. Those regions are filled with high dense of nucleotide variations, these regions are called as “Variation Blocks”. These variations blocks are highly interlinked with the phenotypes. In this study, we established the variant block browser for four functional crops i.e. soybean (31 genomes), rice (23 genomes), sugar beet (7 genomes) and sorghum (44 genomes). This browser is more useful for detecting the recombinant loci and trait associated marker, which are more effective for agricultural traits and to identify agronomical important genes, which could use for gene cloning applications. Moreover, VB browser facilitate genome wide VB visualizations using genome browsers. VB browsers is publicly available as Cropsquare (http://cropsquare.net/).
