| abstract |
The current invention relates to a nucleic acid fragment comprising a resistance allele from L. serriola which confers a broad spectrum resistance to Bremia lactucae, wherein, said resistance allele co-segregates with one or more marker sequences chosen from Seq ID No. 1, Seq ID No. 2, Seq ID No. 3, Seq ID No. 4, Seq ID No. 5, Seq ID No. 6, Seq ID No. 7, and/or any L. serriola genome specific marker in between Seq ID No. 1 and Seq ID No. 7. |
