(2017) QTL mapping for flowering-time and photoperiod Most wild and semi-wild species of the genus Gossypium are exhibit photoperiod-sensitive insensitivity of cotton Gossypium darwinii Watt. PLoS ONE 12(10): e0186240. https://doi.org/ flowering. The wild germplasm cotton is a valuable source of genes for genetic improvement 10.1371/journal.pone.0186240 of modern cotton cultivars. A bi-parental cotton population segregating for photoperiodic Editor: Turgay Unver, Dokuz Eylul Universitesi, flowering was developed by crossing a photoperiod insensitive irradiation mutant line with TURKEY its pre-mutagenesis photoperiodic wild-type G.
