| ABSTRACT The arracacha is a great economical alternative for Brazilian farmers. The aim of this research was to determine the stability and adaptability of arracacha clones by the methodology of factors analysis and bissegmented regression. Five clones, three cultivars (Amarela de Senador Amaral, BRS Rubia 41 and BRS Catarina 64), and two advanced clones (EH-48 and EH-56) were evaluated in 10 locations in the southern of the Minas Gerais State, Brazil, in the agricultural years 2012/13, 2013/14 and 2015/16. The experimental plots consisted of three random samples within the arracacha observation units. Each sample consisted of five plants collected in sequence, highlighting and weighing commercial roots and transforming the portion of the production data... |
