TAILIEUCHUNG - Restoration ability of new inbred and restorer lines on different CMS sources in sunflower (Helianthus annuus L.)

The development of commercial sunflower hybrids based on new CMS sources is of special interest for reducing the potential risk of vulnerability to biotic stresses and for increasing genetic diversity. Four CMS lines of sunflower (Helianthus annuus L.) viz., FMS 852A (Helianthus petiolaris sp. fallax), IMS 852A (H. annuus sp. lenticularis) and CMS 302A and CMS 234A (H. petiolaris) were crossed with 40 inbreds to identify fertility restorer lines for each CMS source. Only a few inbreds could restore fertility on new CMS sources. Out of 25 new inbreds tested, 10 were found to be restorers for CMS PET1. Only two inbreds (RHA-1-1 and IB-60) could restore fertility on CMS PEF, 8 behaved as partial restorers and the remaining 15 inbreds behaved as maintainers. Similarly two inbreds (RHA-1-1 and NS-15) restored fertility on CMS I. Only one inbred line RHA-1-1 could restore fertility on all the three CMS sources. A few effective restorers were identified for the new CMS sources, which can be exploited in developing hybrids with better heterotic potential. | Restoration ability of new inbred and restorer lines on different CMS sources in sunflower (Helianthus annuus L.)
