Abstract：The growth period and agronomic characters of the male -sterile and dwarf male -sterile wheat lines with a blue seed marker and their common backcross male parent were comparatively analyzed un-der the conditions of film mulching or not in overwintering period.The results showed that the dwarf male -sterile wheat line with a blue seed marker owned delayed heading stage and late glume -opening,which lead-ing to the flowering asynchronism with its backcross male parent under conventional cultivation,thus it must be covered with plastic film to keep the flowering period match.Besides,the population of dwarf male -sterile wheat line with a blue seed marker was small,which caused the yield of seed production relatively lower.The male -sterile wheat line with a blue seed marker was same or similar with its backcross male parent in heading and flowering periods,so their flowering phase naturally matched.Its seed setting rate was high,and its yield was equivalent to that of its backcross male parent.Therefore,the male -sterile wheat line with a blue seed marker was a very promising wheat male -sterile line,which was benefit for promoting the marketization of hy-brid wheat.
