Abstract

Three thousand potato clones from 28 hybrid
families of the International Potato Center (CIP) were tested in
the National Institute of Agricultural Sciences (INCA) from
1995 to 2002. The parents of these materials showed resistance
to potato Y and X viruses. Selection was carried out following
the traditional breeding scheme and qualitative characters for
the first, second and third generations and quantitative
characters for the fourth and fifth generations were taken into
account; the presence of Alternaria solani, Streptomyces
scabies, PLRV, PVX and PVY was evaluated. All clones and
Desirée as control were planted in a Randomized Block Design.
Data of tuber number, yield and average weight were subjected
to a Balanced Variance Analysis with a factorial arrangement
(15x2) and an AMMI model was used for genotype-year
interaction. The best behavior was recorded in C-63, C-183,
C-73, C-76, C-81and C-48 clones, concerning yield and its
components, tuber quality and disease performance.
