Abstract
SI presente estudio tuvo los siguientes objetivos;
a) Evaluar el daño causado por las heladas a ~3°C, -4°C y 5°C, de 319 clones pertenecientes a varias especies de papa cultivadas de la coleccion CIP;
b) Selección de progenitores diploides cultivados con diferente nivel de resistencia a las heladas;
c) Cruzamientos de los progenitores seleccionados;
d) Evaluación de las progenies híbridas.
Las diferentes pruebas se realizaron en los laboratorios y campos experimentales del Centro Internacional de la Papa (Lima y Huancayo respectivamente).
The main objetives of the present study were the following: a) To evaluate the frost resistanceat temperatures of -3°CS - 4°C and -5°C of 319 clones of CIP germplasm collection belonging from on several cultivated species. b) To select a group of diploid cultivated clones with dif_ ferent resistance levels to be used in various crosses. c) To evaluate the degree of resistance exhibited by the progenies. The tests for resistance were made in the laboratories and experimental fields of the International Potatr Center in Lima and Huancayo-Peru.
