摘要：

The inheritance of resistance to a highly virulent population of sunflower broomrape (Olobanche cernua) has been studied in R-41, a Spanish sunflower restorer inbred line. Using the cytoplasmic male sterile inbred line HA-89 (cms; very susceptible to this population of broomrape) as a Female parent, progenies of the cross with R-41, i.e. F1, F2 and BCl to both parents, as well as the parental lines, were analysed for their reaction to the broomrape population EC-94. The goodness of fit of the observed vs expected segregation ratios indicated that the inheritance of resistance to broomrape in line R-41 is conferred by two independent dominant genes.
