Details
The study was conducted in 3 environments, La Molina-PERU to 240 masl. during
autumn-winter and spring, and in Huancayo-PERU 3180 masl., during summer.
The experimental material consisted of 24 families half brother in the form
of tubers derived from TPS, obtained crossing between 8 female and 3 male parents.
Design used was randomized complete block with three repetitions.
The experimental unit was 30 plants in two rows at a distance of 30cm
between plants and 90 cm between rows. Variables evaluated were Yield, Tubers number,
Dry matter and content and reducing sugars. The analysis was conducted
line x tester. The control variety was Desiree.
