Molecular analysis of sexual and somatic hybrids of Oryza sativa and O. granulata for comparative genome characterisation. Final Technical Report.
The purpose of the project was to ensure that novel plants produced by somatic hybridisation of O. sativa and O. granulata in previous DFID PSP research are made available for the rice breeding community. It was envisaged that the germplasm could be used to transfer traits to cultivated rice and these may include drought tolerance and adaptability to low levels of solar radiation which occur in the wet season in most areas where rice is grown. Detailed molecular characterisation using microsatellite primers showed that the original population of 55 plants was composed of 33 cybrids and 22 O. sativa plants, of which 7 were somaclonal variants. There are no plans to further utilise this germplasm.
