Correlations between insect resistance and horticultural traits in potatoes
The objective of this study was to determine relationships between insect resistance and some horticulturaltraits and the implications on selection. A potato population of 11 clonal families derived from crosses between insect resistantand genotypes adapted to the southern region of Brazil was used....
