摘要: Development of leaf spots resistant runner peanut cultivars is one the major demands in Brazil. In 2009/10 crop season, 12 pre-breeding progenies (LPM) were selected out 380 plants an interspecific BC1F3 population for resistance and agronomic traits. 2010/11, LPMs evaluated resistance, without fungicide sprays. The recurrent parent (susceptible control) all susceptible; partial segregating selected. Some had yield, pod seed shape similar to control. 12, 5 2011/12 2012/13 seasons, respectively, under appropriate disease management. Differences detected yield weight 100 seeds. Seed/pod ratio, oil content oleic/linoleic ratio thecontrol. Individual market quality. Variability first backcross generation traits will be useful.
