The authors considered three interspecific hybrids between wild Helianthus species and the cultivated sunflower (H.annuus Line A x H.argophyllus, H.annuus Line A x H.bolanderi, H.annuus Line A x H.debilis.) with the aim of examining their morphological, biometrical, biological and technological characters. An A.N.O.V.A. and path coefficients were made. Results show that these hybrids maintain several characters of wild types although the trend is to get to the cultivated ideotype. A normal desaturation activity is present; moreover, path analisys reveals that oleic acid may be increased by flowering height in H.annuus x H.argophyluss, by leaves number in H.annuus x H.bolanderi and leaf surface in H.annuus x H.debilis.Finally oil content may be increased by unsaturated acids in H.annuus x H.argophyllus and is not influenced by environmental conditions in all three hybrids.
