Abstract: Using ms₅ms₆ male-sterile lines with Bt gene and transgenic Bt cotton Rg3 as parents, honey bees as pollination media, releasing honey bees in field during producing hybrids, three years experiments were performed in Yangtze River and Yellow River Valley Region. In the system of honey bees pollination producing cotton hybrids, the parents plant proportion, bee varieties, parent plant patterns, honey bees behavior and weather influence were studied. These preliminary results were as follows: 1∶4 proportion of parents was ideal, honey bees were better than bear bees in pollination effect, there was no remarkable difference between mixing plant patterns and alternating plant patterns, weather had obviously effect on honey bees pollination, which lead to direct hybrid yield loss.
