Abstract

Low yields, climate change effects and
heterogeneous culture conditions are some reasons for
the development of new rice cultivars. This trial was
developed with the objective of studying the behavior of
sixteen advanced lines of rice under flooded conditions
and to select the best for moving on to a higher stage.
A Completely Randomized Design with three replications
was used, the genotypes constituted the treatments and four
commercial control were used. The available information
was processed statistically by the combination of univariate
and multivariate analysis. Results showed correlation of the
yield with all their components, the cluster analysis detected
that the maximum genetic diversity between types V and
VI and the minimum was detected between types I and
II and the regression indicated that the model had a good
adjustment (93.5 %). The combination of statistical analyses
used allowed to select five more promissory lines and to
propose its validation.
