Interpretive Summary:

Technical Abstract: DNA marker technology offers a valuable tool for revealing the genetic basis of both simple and complex traits in crop plants. Among monogenic traits of cultivated cotton (gossypium hirsutum L. and G. barbadense L.) are glandless and photoperiod sensitivity, each of them is controlled by a dominant allele at a single locus. The Glandless gene was transferred to Texas marker TM-1 (G. hirsutum L.) from an Egyptian cotton Bahtim 110 (G. barbadense L.), resulting in a new alternative genetic system to glandless cottonseed breeding programs. A cotton plant with or without the Photoperiod sensitivity gene will result in flowering or non-flowering. In this paper, mapping of these two genes via linkage to DNA markers will be discussed. The chromosome location of linked markers will be determined using a set of aneuploid cottons. The applications of these molecular tags in cotton improvement and basic developmental studies will be discussed.
