Resumen
- Potato (Solanum tuberosum L.) is the fourth most important crop in the world aQer corn (Zea mays L.), wheat (Tri2cum aes2vum L.) and rice (Oryza sa2va L.)1. It is consumed by people worldwide either as a non-grain staple or as a vegetable. It has high nutrient value because it provides source of carbohydrates, proteins, vitamins and minerals2. The most important group of Solanum tuberosum is Andigenum, that contains autotetraploid potatoes (2n=4x=48) known as Andigenas; they are highly heterozygous with tetrasomic inheritance, adapted to tuberizaGon under short-days and presenGng tuber dormancy3. They can also be diploids (2n=2x=24) such as the group Phurejas that are adapted to short days, have short vegetaGve period, form small tubers and lack dormancy4. Others potatoes inside the group Andigenum are triploids (2n=3x=36) know as Chauchas
