Results
are presented that bring concrete solutions to the agrarian necessities
of cassava in Cuba. This
has contributed to the development of the crop’s cultivation and has
brought significant increase in the efficiency and qualities of the
plantation material through the application of biotechnology.
A scheme has been established for initial material production, which is
acclimatized and cultivated in a first cycle under adequate proper
conditions. Cuttings
from in
vitro
plants are used as original asexual material to establish the
scheme of "seed" certification.
A group of specialized enterprises and advance producers, under
the advise of the investigators and taking into account their criteria,
receive a material of the new genotypes and commercial clones, and have
been planted in the field in a comparative way with the traditional
clones possessed their own areas. The
results obtained during five years of experience have increased ties
between the researchers and producers.
It has been possible to achieve a superior level of adoption of
the technology and new cassava genotype by the latter group.
It has been also possible to select and rejuvenate traditional
commercial clones of the producer and to increase their yields.
The introduction of these methods guarantees the qualitative and
quantitative aspects of the plantation material, and reduces the time
between obtaining clones and its use for the producers, to two or three
years depending on the conditions of the region.
This investigation has demonstrated validates the value of
participation of the producer the potential of the biotechnology for the
development of this crop.
