Abstract

Over 2002-2003, 2003-2004 and 2004-2005
seasons, 63 wild species from the Cuban potato germplasm
were studied at the National Institute of Agriculture Sciences.
A morphoagronomic characterization of the species was
conducted, including the following qualitative characters: tuber
shape, tuber colour and eye depth as well as the quantitative
ones as: yield per plant (t.ha-1), average tuber weight, tuber
number per plant and stem height. Also, its behaviour versus
A. solani and potato leaf roll virus (PLRV) was evaluated. The
qualitative characters are presented by its percentage within
the collection. With regard to the quantitative ones, the
descriptive statistics as media, maximum and minimum values,
standard deviation and coefficient of variation were determined.
A main components analysis was performed to know the
distribution of each species within the collection and its
possible use in Cuban potato breeding program. A high
variability was recorded among the wild species collection for
the environmental conditions of Cuba, and the resistant
sources for A. solani and PLRV. This work proved there is an
extended gene pool in this collection, to be more efficiently
used in Cuban potato breeding program.
