摘要：
The present invention presents a method for obtaining female inbred lines from Asteracea hybrids, using the species Helianthus annuus as a model. The method of the invention is based on the modification of lines with the fertility restorer gene (Rf), obtained from self-pollination of hybrids, in lines presenting normal cytoplasm and not containing the Rf gene. Further, derived male sterile lines were developed. Through the use of this methodology it was possible to obtain female lines from commercial hybrids of sunflower.
