Mu. Patwary et Jp. Vandermeer, CONSTRUCTION OF BACKCROSSED GELIDIUM MALE-STERILE AND MALE-FERTILE LINES AND THEIR GROWTH COMPARISON, Journal of applied phycology, 8(6), 1996, pp. 483-486
The male sterility gene from a male-sterile, green, Gelidium vagum lin
e 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 m
ale-sterile lines were compared for their growth performance. The back
cross-5, red, male-sterile plants grew at a significantly higher rate
than the plants from other lines, suggesting that male-sterile gametop
hytes would likely be better candidates for aquaculture than normal wi
ld-type plants of this species. This study also provides evidence that
the growth rate of G. vagum decreases as a consequence of reproductio
n.
