Agronomic characterization of three rice (Oryza sativa L.) cultivars obtained by in vitro anther culture
Main Article Content
Abstract
Cuban population’s diet; therefore, great efforts have been
dedicated to breeding studies on this crop. In this sense, a
methodological procedure was developed to obtain three rice
cultivars, which were planted along with their progenitors under
field conditions and agronomically characterized by using
32 qualitative and 19 quantitative descriptors. Results
showed a significant and positive correlation between
agricultural yield and panicles per square meter and full
grains per panicle, whereas a negative correlation with rice
Blast effects. Thus, the use of hypocotyl length is suggested
as a selection marker in early seasons. All cultivars, were
able to form a large number of fertile tillers, despite showing
a short-term cycle, which enabled them to achieve the
highest yields, with the help of full grains per panicle and
1000-grain mass components.
