GENERATION OF HAPLOIDS BASED ON MUTATION OF SAD2
The invention identifies plants carrying certain mutations, which can be used as haploid inducers or doubled haploid inducers in plant breeding. According to the invention, significant haploid induction and even doubled haploid induction rates can be observed when at least one functional mutation wi...

| description | The invention identifies plants carrying certain mutations, which can be used as haploid inducers or doubled haploid inducers in plant breeding. According to the invention, significant haploid induction and even doubled haploid induction rates can be observed when at least one functional mutation within a SAD-homology domain is present, wherein the functional mutation affects the expression of certain SAD-homology consensus sequences. The present invention further provides haploid and doubled haploid plants, which are obtained by contacting a first gamete from a plant as identified according to the invention with a second gamete from a plant expressing a wild-type SAD-homology domain to generate a zygote. Furthermore, the present invention relates to a method for identifying a plant having the activity of a haploid inducer or a doubled haploid inducer in a plant population. |
