^a"HA52" is an accession putatively originating from Romanian germplasm bred in Potchestfrom, Transvaal, South Africa.
^bThird generation backcross of "Mennonite RR" to "Commander".
^c"Charata INTA" was obtained by interspecific crossings with wild germplasm belonging to species H. annuus subsp. annuus and H. petiolaris.
^d"Guayacán INTA" derived from a cross between the Argentine variety Klein and "CM953-102" and backcrossed once again with "Klein".
^e"KLM" is a multiple cross between cultivars Klein × Local (a pool of local varieties of INTA Pergamino breeding program including "Guayacán INTA", "Charata INTA") × "Manfredi" (a pool of varieties from INTA Manfredi breeding program including "Impira INTA", "Cordobés INTA", "Manfredi INTA").
^fT66006-2 comes from Peredovik*2/953-102-1-1-41.
^g"V94" is another Argentine selection of a cross between cultivated sunflower ("MP543") and wild species (H. argophyllus), "MP543" derives from "MPRR" (mezcla precoz resistente a roya: pool of early material resistant to sunflower rust), which also derives from wide crossings with Helianthus wild species.
