SELECTING AND BREEDING METHOD OF HIGH-OIL RESTORE SYSTEM ON HYBRIDIZED SUNFLOWER

On the basis of sunflower breeding for many years, through profound studies and the problem in practice, the feasible method for selecting high-quality and high-oil proportion on the restore system of sunflower was proposed. The foreign high- oil 3 "system" sunflower hybrid is an important breeding resources, the restore system with aimed genes was obtained through selecting 2 circle system. Then the high - oil gene was transfered into the present restore system through hybrid, a new high - oil restore system was produced; the descendants of interbread was selected for high- oil restore system; The self- line of high- oil and high quality variety could be transfered into through backcross. The aimed genes obtained through recurrent selection in whole family. At last the good restore system was created.
