Analysis of Cuban potato hybrid progenies as an alternative of crop spreading from botanical seed
Main Article Content
Abstract
semicontrolled conditions over the years 2004-2005, 2005-2006
and 2006-2007, with the objective of analyzing the behaviour
and external quality of tubers from eight crosses or hybrid
combinations. Sowings were performed in the first week of
December. Thus, 300 seedlings were selected to be
transplanted to more technical beds inside a greenhouse; they
were transplanted after 25 days using a randomized block
design with three replicates. Progenies from true potato seed
during the years tested showed a differential behaviour. The
Cuban progeny Atlantic x Aninca reached the highest tuber
number and weight (346.1 tubers and 3.7 kg/m2); besides, its
skin color and tuber shape (degrees 9 and 8 respectively)
recorded the greatest uniformity. The botanical seed from the
Cuban progeny Atlantic x Aninca constitutes a sowing
alternative for producing potato, considering its yield and
uniformity. It is recommended to obtain botanical seed from
this Cuban progeny on a business scale as well as to conduct
zonal ecological studies.
