Abstract

The state of São Paulo is the largest peanut producer in the country, accounting for more than 90% of national production. This work aimed to evaluate the agronomic potential and the response to viruses of breeding lines developed by assisted selection for resistance to the root-knot nematode. Sixty- two lines were evaluated for yield, 200-kernelweight and pod yield, in Federer's augmented blocks with the cultivars IAC OL 3 and IAC 503 as regular treatments. These genotypes were also planted in the municipalities of Bastos/SP and Santa Adélia/SP, at locations where virus occurrence has increased in peanut crops along recent years, causing significant damages. In Bastos, the plots consisted of 3 lines of 10 m in length. In Santa Adélia, the lines were evaluated in randomized blocks with three replications, in plots with a single row of 20 m. It was concluded that the nematode resistant selected lines have diversity for virus tolerance and agronomic potential for yield and kernel quality.
