Notes:
G. hirsutum L. and G. barbadense L.) were found to be morphologically distinct. Confocal microscopy was used to construct a three-dimensional image of the fluorochrome-stained pollen grains. Cytogenetically deficient stocks of cotton were used for locating genes for pollen development to chromosomes and chromosome arms. Results indicated that the pollen size and spine pattern were significantly different between TM-1 (G. hirsutum) and 3-79 (G. barbadense). Comparative analysis of pollen morphology of parental and interspecific hybrid, monosomic, and monotelodisomic plants indicated that gene(s) responsible for pollen spine development were located on the long arm of chromosome 12. The segregating nature of pollen morphological features indicated that the gametophytic gene(s) of the microspore partially controlled the pollen size and spine formation during pollen grain development.
