dc.descriptionSix intra-specific crosses among three commercial varieties and four clones from the International Potato Center (CIP) were studied under greenhouse conditions for two years. The aim of the work was to evaluate the behavior of the parents at the crossing time and during true potato seed stage to be used as parents in a true potato seed program. Percentages of pollen viability and germination, fruit set, total seed number, seed number per fruit, as well as berry length and diameter, were evaluated. Hybrid seeds were sown in wooden boxes containing organic matter and soil mixed at a rate of 1:1. Seed germination was determined seven and 10 days after seeding. Seedlings transplanted into nylon bags were evaluated with regard to survival percentage, stem height, uniformity, and vigor. Desirée x Kondor was the best cross to be used in a true potato seed program; however, the highest values of survival, vigor and uniformity were obtained when CIP clones were used as male parents.
