Morphological and agronomic response in greenhouse the in vitro plantlets of two varieties of cuban potato
Main Article Content
Abstract
production of original seed by biotechnological methods
help to reduce imports by the concept of buying seed. The
present study was to determine the morphological and
agronomic response of cultivated in vitro plantlets of two
varieties of Cuban potato. Grettel and Yara varieties from
breeding program of the National Institute of Agricultural
Sciences (INCA) were used and planted in the greenhouse.
The plant height and number of stems per plant was
measured. Subsequently at the time of harvest the number,
weight and size of the tubers per plant were quantified.
Furthermore, the form of tubers and the skin color in each
variety were evaluated. As a result, to produce of original
seed of two Cuban varieties included in the national seed
production program were gotten. The morphological
differences between varieties of Cuban potato Yara and
Grettel in greenhouse from in vitro plantlets were found. The
Grettel variety had the highest number of tubers per plant
but smaller calibre than Yara. These results allow to plan
the production of original seed potatoes of two varieties by
biotechnological methods.
