This investigation describes two partial male sterile plants of guar, Cyamopsis tetragonoloba (L.) Taub. (MS‐1 and MS‐II), and gives results of their hybridization with a fertile cultivar. Detectable natural crossing between MS‐1 plants and a fertile cultivar averaged 20.6%, with maximum crossing of 70 %. Crossing between MS‐II plants and a fertile culuvar averaged 5.0 5.0 % about the same as previously reported for fertile × fertile, crosses. Honeybees, Apis mellifera (L.), caged with MS‐II plants and a fertile cultivar did not increase seed set on male sterile plants. Hand separation of mature pods into short‐ and long‐pod groups was only partially effective in identifying hybrid seed produced on the male sterile plants.
