Evaluation of potato (Solanum tuberosum L.) genotypes for reproductive and agronomic characters
Main Article Content
Abstract
characters was conducted in 1005 genotypes from a different
origin -870 clones of the National Potato Breeding Program
and 135 foreign commercial varieties of certified category- at
the National Institute of Agricultural Sciences (INCA) for two
seasons (2004-2005 and 2005-2006). The following reproductive
and agronomic characters were evaluated: flower color, skin
color, flesh color, tuber shape, yield and tuber number. The
occurrence of Alternaria solani and Streptomyces scabies was
recorded by degree scales. The statistics of position and
dispersion as well as confidence intervals were calculated for
quantitative characters; Chi-square test was employed to compare
proportions for the qualitative characters. The minimum,
maximum and medium values of both disease occurrences were
determined. A low number of 113 genotypes flowered and
formed fruits within the two years studied. On the other hand,
flowering ranged over a relatively short period between 28 and
38 days. With regard to flower color, there were white, purple
and red flowers. Concerning tuber skin color, 84 % genotypes
were yellow, 11 genotypes (10 %) were pink and seven
individuals (6 %) were red. For tuber shape, genotypes with
round tubers did not differ from the oval ones, reaching 33 and
32 % respectively. These results could be used to select parents
for varietal breeding and obtain true potato seed offsprings.
