METHOD FOR RAISING LODGING RESISTANCE WHILE MAINTAINING YIELDS AND LOW GLUCOSINOLATE CONTENT OF A BRASSICA PLANT

摘要

The present invention is related to Brassica plants with a reduced height or increased lodging resistance, which comprise at least one mutant dwarfism allele of the encoding gene of the DELLA protein, nucleic acid consequences, representing the mutant dwarfism alleles DELLA, and the mutant dwarfism proteins DELLA. The present invention describes a method for increasing the lodging resistance, while keeping yield and the low glucosinolate content of a Brassica plant, which includes introducing the mutant dwarfism allele DELLA into genome DNA of the stated plant by means of transforming or mutagenesis and breeding of the stated mutant alleles DELLA, in which the stated mutant dwarfism allele DELLA encodes a protein with the consequence, in which proline, corresponding to P91, is substituted by leucine.
