Heritability and Early‐Generation Selection for Resistance to Early and Late Leafspot in Peanut

The genetic nature of resistance to early (Cercospora arachidicola Hori) and late [Cercosporidium personatum (Berk. & Curt.) Deighton] leafspot of peanut (Arachis hypogaea L.) is quantitative, making selection for resistance difficult in segregating populations. In many areas of peanut production, without fungicide application one or both diseases may significantly reduce yields. A study was conducted to obtain heritability estimates, responses to selection, and relationship of resistance of two peanut populations for early and late leafspot resistance (...)
