The present invention relates to a polynucleotide encoding a mutated patatin phospholipase protein, which mutated protein leads to an improved haploid induction rate. The invention further relates to the mutant patatin phospholipase protein and to methods and compositions for improved plant breeding using haploid induction. Sorghum plants which are capable of haploid induction with improved induction performance are described. La présente invention concerne un polynucléotide codant pour une protéine de phospholipase de patatine mutée, laquelle protéine mutée conduit à un taux d'induction d'haploïdes amélioré. L'invention concerne en outre la protéine de phospholipase de patatine mutante, ainsi que des procédés et des compositions pour une amélioration de la sélection de plantes à l'aide d'une induction d'haploïde. L'invention concerne également des plantes de sorgho qui sont capables d'induction d'haploïdes avec des performances d'induction améliorées.
