1. Significant difference was observed on the pollen quality of the following 6 potato varieties: Corahila corriente, Cunca, Corahila rosada, President, Centinela 1239, and Llanquihuana, grown in 5 different localities: Ovalle, Los Andes, Chanco, Temuco, and Centinela. 2. This difference on the pollen quality was not due to temperature (mean, extremen maximum, mean maximun, mean minimum or extremen minimun) or to precipitation. Nevertheless, a significant correlation was found between "pollen quality" and "relative humidity" of the locality on the flowering period. These date show that "Centinela" is a desirable locality for potato breeding. |
