Screening of sweet potato clones resistant to soil insects

A research was carried out with the objective of selecting commercial clone s for weather conditions of the Triangulo Mineiro, Minas Gerais State, Braz il. Sixty of the clones evaluated were obtained by polycross and given by t he Universidade Federal de Lavras, three were from the farmers of the munic ipalities of Araguari, Uberlandia and Machado, located in Minas Gerais Stat e, and nine clones were used as standards (Brazlandia Branca, Brazlandia Ro sada, Surpresa, Rio Doce, Morena Roxa, Coquinho, Arroba, Pira 1 and Clone 0 42). The experiment was installed in a spacing of 1.10 x 0.45 m, using a ra ndomized block design, with 72 treatments, four replicates and 16 plants pe r plot. Among the evaluated clones, 32.8% showed high or moderate resistanc e to soil insects. The clone with the highest yield was the clone number 95 041, which produced 28,048.96 kg/ha. The others, 95009, 95010, 95014, 95020 , 95033, 95042 and 95057 were highly resistant to soil insects.
