Abstract

Abstract

A sequential selection method is proposed to minimize genotype ✕ environment interactions. The sequential method involves cycling early-generation selections through different environments, as opposed to practicing selection at the same location each year. To evaluate this method, a cooperative peanut (Arachis hypogaea L.) selection study was conducted in Georgia, North Carolina, and Oklahoma. Pedigree and sequential selections and single seed descent were compared each of 3 yr for yield and leafspot [Mycosphaerella arachidis Deighton (anamorph: Cercospora arachidicola S. Hori) and Mycosphaerella berkeleyi Jenk. (anamorph: Phaeoisariopsis personata Berk. & M.A. Curtis/Arx)] resistance. Sequential selections were comparable to or significantly better than the pedigree selections in leafspot rating and yield performance. Individual sequential selections were also found with combined leafspot resistance and high yield. In general, the sequential selection method proved to be an alternative approach for peanut breeding.
