ABSTRACT:
A process is provided for selecting cotton plants which exhibit naturally-occurring genetically-controlled herbicide resistance. Initially cotton seeds are subjected to cold stress (as described) and cotton plants are formed from the seeds that germinate. Seeds are formed following the self-pollination of the resulting plants. These seeds upon maturity are soaked in a liquid containing a herbicide (e.g., a glyphosate) for a period of time sufficient for the herbicide to reach the embryos of the seeds. The seeds following such soaking are planted in a growing medium and produce at least one cotton plant that displays herbicide resistance. The plant is analyzed for the possible presence of a foreign gene for herbicide resistance that would attribute the manifest herbicide resistance to genetic engineering. A cotton plant is selected wherein the herbicide resistance is not attributable to genetic engineering.
