Abstract

The current development of researchers in the
field of genetic improvement in Cuba and the necessity of
economizing experimental area and resources outlines the
necessity to value experimental designs that facilitate an
appropriate efficiency with a maximum of economy. This work
intends to combine the kindness of DAM, with the adjustment
method for line-column to control the soil heterogeneity, and
the statistical multivariate techniques, offering the investigator
a mathematical tool in the selection of test lines in rice breeding
programs. DAM was structured by means of a Latin Square
(4x4), with four controls lines (INCA LP-5, INCA LP-2, J-104
and Reforma) and 120 test lines distributed at random in the
corresponding subplot. The use of DAM that allows to compare
a considerable number of test lines, overcoming the limitations
of a not replied experiment, what presupposes an economic
benefit for the area reduction, the economy of experimental
material and control of the environmental heterogeneity, in
combination with statistical multivariate techniques provides
a methodology more efficient in the selection of promissory
lines in rice breeding program.
