The Yungara Potato, One of the Best Varieties of the Ecuadorian 

 Highlands. (Solanum tuberosum L.; S. P. I. No. 53195.) 



The Andean region, native home of the potato, contains many cultivated forms of interest 

 and possible value to plant breeders. Some may prove useful in the development of early or 

 late varieties; others may be found blight resistant; and still others are valuable for their 

 excellent flavor and quality. Many have been introduced into the United States for trial. 

 Yungara, a productive and late-maturing sort and one of the principal commercial varieties 

 of Ecuador, where it is cultivated at altitudes between 10,000 and 12,000 feet, may be taken 

 as an example of the best sorts which have been produced in the Andes. (Photographed, 

 natural size, by Wilson Popenoe, Ambato, Ecuador, January, 1921; P18334FS.)
