The present invention provides an improved-resistant plant, in particular a maize plant which comprises a polynucleotide with one or more resistance-conferring genes, for example on a truncated chromosome fragment from the accession Pepitilla, as well as a cell, a tissue, a part, grain and seeds thereof, an isolated polynucleotide which comprises one or more resistance-conferring genes against, a vector, a transgenic plant cell and a transgenic plant containing this polynucleotide. Furthermore, the invention encompasses suitable markers and their use in introducing resistance or the transgene into a plant, as well as the identification of improved maize plants which comprise a truncated chromosome fragment.

The present invention relates to the identification and molecular characterization as well as to the use of genes and markers from a chromosomal interval which has a locus for cold tolerance in maize. The invention further relates to the development of molecular markers for assisting in growth, in particular for preventing a fixing of a 'selective sweep' in a region with a low recombination rate, and to the provision of transgenic and non-transgenic plants, in particular maize plants, which show a newly mediated or increased cold tolerance.
