prostrate, spindly, and chlorotic. After 7 d of submergence, only
30.7% of the second leaves of M202 were intact, whereas all
leaves of M202(Sub1) were fully green. The viability of the coleoptile
and first leaf was not significantly different in the two
genotypes after 7 d of inundation. After a more prolonged submergence
(14 d), all of the first and second leaves of M202
appeared brown and withered, whereas all of the first leaves and
81.3% of the second leaves of M202(Sub1) were fully green and
appeared undamaged. The coleoptile of M202(Sub1) was also
considerably more tolerant to 14 d of submergence. Viability
after 14 d of submergence was significantly different in these
lines, as judged by the emergence and growth of the third and
subsequent leaves
