The present invention relates to a mutated nucleic acid sequence of a delta-12 oleate desaturase enzyme (FAD2)&#x2014;encoding nucleic acid from a Cruciferae plant, wherein said mutated nucleic acid sequence comprises the non-conservative mutation of at least one nucleotide of at least one codon representing an amino acid selected from the group consisting of: &#x2014;the amino acid at position 259 of the amino acid sequence of said FAD2, &#x2014;the amino acid at position 216 of the amino acid sequence of said FAD2, &#x2014;the amino acid at position 90 of the amino acid sequence of said FAD2, &#x2014;the amino acid at position 116 of the amino acid sequence of said FAD2, &#x2014;the amino acid at position 276 of the amino acid sequence of said FAD2.

The invention relates to a method of producing a double low restorer line offor Ogura cytoplasmic male sterility (cms) presenting a radish introgression carrying the Rfo restorer gene deleted of the radish Pgi-2 allele and recombined with the Pgi-2 gene from, and having a good agronomic value characterized by female fertility, a good transmission rate of Rfo and a high vegetative vigour. The invention relates also to a method of forminghybrid seeds and progeny thereof and to the use of markers for selection.

The invention relates to the production of plants with reduced development and a mutant gene of the GRAS family.
