Performance of potato (Solanum tuberosum L.) hybrid progenies derived from true seed
Main Article Content
Abstract
progenies from CIP were studied in the Potato and Fiber
Research Station belonging to �??Liliana Dimitrova�?�
Horticultural Investigation Institute. Seeds were put in beds
on a compacted Red Ferralitic soil. Progeny behavior in
presence of Alternaria solani and Phytophthora infestans
fungi was evaluated 65 days after seeding. The experiment
was harvested 100 days after seeding. Tuber number/m2 and
yield (kg/m2), skin color and shape uniformity were evaluated.
A Randomized Block design with three replications was used.
Data were subjected to a Balanced Variance Analysis with
(15 x 2) factorial arrangement and means were compared
according to Duncan�??s Multiple Range Test at 5 %. As a result,
five hybrid progenies were selected: HPS I/13, Serrana x TS-5,
MFI x XY.13, Serrana x XY.13 and TS-6 x TPS-67 for their nice
tuber yield per m2, appropriate performance in presence of
fungi and a good tuber quality.
