Abstract
Institute of Agricultural Sciences (INCA), where a Triticum
genus collection was evaluated, with the purpose to compare
different wheat species under our western conditions. These
were Triticum aestivum ssp aestivum, Triticum turgidum ssp. durum
and X Triticum secale Wittmack. A randomized block design
with four repetitions was used. The evaluated variables
comprise: plant height (cm), spike length (cm), weight of 1000
grains (g) and yield (t.ha-1). For every variable studied, a
descriptive statistics was used, estimating the mean and typical
deviation per species. The Cuban variety CC-204 was used as
control. Therefore, the data matrix obtained was processed by
the Main Components technique. All experimental data were
processed by SPSS 11.0 for Windows. Most genotypes showed
a mean general performance, although some floury wheat and
triticale genotypes stayed apart from the rest. The mean and
standard deviation values for all variables showed no
differences per species, however, hard wheat plants were the
smallest ones, the best genotypes being: 12 and 54 from
T. aestivum (floury wheat); 17, 18 and 25 from T. durum (hard
wheat); 29 and 37 from X Triticum secale (triticale).
