Phenotypic Stability for tuber yield, Late Blight resistance in advanced clones from B3C3

Abstract

In a selection process started in 2011 and involving 30,000 genotypes from the breeding group B3C3, 18 clones showed high phenotypic stability for tuber yields from 25.7-31.1 t ha-1. Moreover, 13 clones combine stability for commercial and total tuber yield and late blight resistance; these clones will be considered directly for variety release or will be further used in crossing plans of our national partners in Asia.
