Abstract
Seven perennial species of wild Helianthus screened in the laboratory for resistance to the aphid Masonaphis masoni (Knowlton) were significantly (5% level) more resistant to M. masoni than either 5 wild annual species or ‘Hybrid 896’. Mortality of M. masoni was 100% on H. x laetiflorus Pers., and H. tuberosus L.This publication has 0 references indexed in Scilit:
