This report is a summation of the background, objectives, and acltievements of the research project funded by CRDC grant CSP4 7C. We would like to emphasize four particularly notable Q achievements. * We assessed the risk of trans gene escape from commercial cotton cul ti vars into wild Australian cotton species * We synthesizing 18 new fertile intergenomic Gossypium polyploids * We documented the production of umeduced gametes in hybrids between cultivated cottons and wild species indigenous to the Kimberley Plateau. * We synthesized self. fertile cotton germplasm lines that incorporate genetic material from wild cotton species.
