Abstract

Fertility restoration in four CMS sources of sunflower was studied using 12 diverse restorer lines, while fertility was completely restored in only 27 hybrids, 15 of them were partially restored and rest six were found to be completely sterile. The tester lines SCG 29, SCG 73, RES 834-1, HRHA 10, RHA 298 and ID 25 were found to be common restorers of three CMS lines viz., CMS 234A, CMS 17A and CMS 1030A and it was found that there is no line that was completely sterile on CMS 234A and CMS 1030A sterile lines. The differential behaviour of these pollen parents on different CMS lines could be due to their wide genetic diversity as these restorer lines are interspecific derived lines.
