This research is needed to ascertain if outcrossing percentages are adequate in certain environments so that the pollen parent for hybrid barley can be developed. We investigated the effect of environment on natural outcrossing in these populations containing genetic male sterility. The genetic male sterile recurrent selection populations were developed at Bozeman by selecting male sterile plants each generation and planting the outcrossed seed from these plants in the following generation. The seed set obtained in the genetic male sterile populations was satisfactory in these relatively undeveloped populations when environmental conditions were not hot and dry.
