Abstract

The experiment was developed at the Plant
Genetics Department from the National Institute of Agricultural
Sciences, where a group of rice mutants (Oryza sativa) coming
from irradiations with protons of the variety Amistad 82 were
taken, with the objective of determining their behavior at
different saline concentrations (0, 4 000 and 7 000 ppm). After
seven days, dynamics and final percentage of germination
were evaluated and 20 days later, height, plant root system
length, as well as the production of root and leaf dry mass
were also evaluated, showing a different genotype behavior
at several saline tenors. Radiomutants L - 8553, L - 8554 and
L-8555 showed the best behavior at the parameters analyzed
for this stress type, in comparison to the donor plant. In general,
with the increase of saline concentrations, an inhibitory
effect was recorded in all characters evaluated.
