Sampling nucleotide diversity in cotton Chapter uri icon

abstract

  • 2012 by Apple Academic Press, Inc. Cultivated cotton is an annual fiber crop derived mainly from two perennial species, Gossypium hirsutum L. or upland cotton, and G. barbadense L., extra long-staple fiber Pima or Egyptian cotton. These two cultivated species are among five allotetraploid species presumably derived monophyletically between G. arboreum and G. raimondii. Genomic-based approaches have been hindered by the limited variation within species. Yet, population-based methods are being used for genome-wide introgression of novel alleles from G. mustelinum and G. tomentosum into G. hirsutum using combinations of backcrossing, selfing, and inter-mating. Recombinant inbred line (RIL) populations between genetics standards TM-1, (G. hirsutum) 3-79 (G. barbadense) have been developed to allow high-density genetic mapping of traits.
