Abstract
The male sterility gene from a male-sterile, green,Gelidium vagum line was introduced to a wild-type line through repeated backcrossing and selection for five generations. The plants from the recurrent parent, the male-sterile green, the backcross-5 fertile and the backcross-5 male-sterile lines were compared for their growth performance. The backcross-5, red, male-sterile plants grew at a significantly higher rate than the plants from other lines, suggesting that male-sterile gametophytes would likely be better candidates for aquaculture than normal wild-type plants of this species. This study also provides evidence that the growth rate ofG. vagum decreases as a consequence of reproduction.
