Technical Abstract: The genus of Gossypium consists of more than 50 species that provide primary and secondary gene pools essential for cotton improvement. Yet, the genetic potential of these gene pools is barely exploited due to various factors including the cotton industry's transgenic breeding program that heavily relies on very few transformable genotypes. Characterization of significant variants inherited through the cotton breeding process has been challenging. With the recent sequencing of several diploid and tetraploid cotton genomes, abundant DNA variation is uncovered within and among the Gossypium species and accessions. In concert with the phenotypic observation, such DNA variants are being associated to priority traits including fiber and seed quality properties as well as biotic and abiotic stress tolerance. Now, it is possible to exploit the beneficial genetic variation that may facilitate and expedite molecular breeding of cultivated cottons. The current status and future perspective will be discussed.
