Morphoagronomic evaluation of the genetic diversity of local maize varieties in La Palma, Pinar del Río
Main Article Content
Abstract
low input conditions, maize landraces were collected from nine
farmers in �??El Tejar-la Jocuma�?� community, La Palma, Pinar del
Rio. 15 ears per farmer were evaluated according to quantitative
and qualitative characters, following the approaches of
specialized maize describers. Landraces were grouped by a
Cluster Analysis, starting from the evaluated quantitative
characters. Qualitative characters were analyzed according to
a descriptive statistics. Parents and its half sib families were
evaluated by a detailed analysis between and within farmers;
whereas a multivariate analysis was applied to ear quantitative
variables. A wide variation was detected for most variables
analyzed, which supposes a wide genetic diversity of the
materials with potential adaptation to low input conditions.
The existing differences among peasants should be
highlighted, either for parents�?? or for progenies�??analyses (half
siblings), suggesting that in spite of the possible crossing
level among samples, the farmers present their own varieties,
with specific patterns inside each of them. These differences
could be mainly due to several forms of handling their own
varieties or seed selection for sowing.
