Abstract

We have developed a methodology that enables us to identify, in Arabidopsis thaliana, genes for which transcript abundance is correlated with the magnitude of hybrid vigour (heterosis) shown by hybrids of inbred accessions. Bio-mathematical models have been developed that enabled successful prediction of heterosis in untested hybrids, based upon transcriptome characteristics of both hybrids and inbred parental lines. Heterosis is exploited as a means of improving the yield of several important crops, including maize, rice and oilseed rape. The objective of the project is to assess whether the methodologies developed in Arabidopsis can be used for the prediction of yield in maize hybrids. If successful, the technology would enable predictive approaches for the acceleration of hybrid breeding, to identify genes involved in agronomic traits and to screen germplasm collections for the presence beneficial alleles.
