Diversity among sources of cytoplasmic male sterility in sunflower (Helianthus annuus L.)
Copyright policy )Diversity among sources of cytoplasmic male sterility in sunflower (Helianthus annuus L.)
Ten cytoplasmic male sterile (CMS) sunflower (Helianthus annuus L.) lines were crossed with nine maintainer or male fertility restorer lines in a diallel crossing scheme. Based on fertility restoration of the F1 generation, CMS lines were divided into four groups. At least two new sources of CMS, CMS PET2 and CMS GIG1, were found to be potentially useful for commercial production of hybrids. Environment had an influence on fertility restoration of one CMS line, CMS MAX1. Effective restoration of male fertility for CMS RIG1, CMS ANN2, and CMS ANN3 was not found.
