Özet:

 





Hybrid rice has an average
15 % to 20 % yield advantage over inbred lines. The availability of stable cytoplasmic male sterility
system is vital for commercial hybrid rice. The experiment was conducted to
develop japonica type CMS lines of national rice varieties. National varieties
were tested to determine as maintainer, CMS or restorer features via test
cross. The test crosses were made by using 19 japonica type national rice varieties
and 21 CMS lines and 1 restorer line.  All national rice varieties which tested are
determined maintainer features. In addition to, 5 CMS introduction lines and 1
restorer lines adapted Mediterranean ecological condition for hybrid breeding
process. Two maintainer were backcrossed for 6 generations and it was developed
similar agronomic features and 100% spikelet sterile CMS lines. For production
of CMS lines Osmancik-97 and Kiziltan, it was employed wild abortive rice which
is CMS V20A. Successive backcrossing of varieties succeeded to produce
completely male sterile CMS lines. Wild abortive cytoplasm did not affect
agronomic characteristic. Since Osmancik-97 is one of the most popular
varieties and it was used as a donor gene for new varieties, the WA-CMS lines
of Osmancik-97 and Kiziltan will be useful for hybrid rice breeding.
