This IREC Farmer newsletter report on progress of rice microspore culture to fast track new varieties. The current conventional plant breeding methods takes 8-10 generations. By using the method of anther and or microspore culture techniques this can be reduced to just 12-18 months. The method is undertaken by uses immature pollen grains or microspores that contain one set of chromosomes known as haploids. These can be grown on a specialised culture medium and induced to divided and double the chromosomes therefore developing two sets of chromosomes that become double haploids. By establishing a microspore culture system at Yanco it would allow the breeders to develop varieties faster as there would be direct access to doubled-haploids
