摘要：
The present invention relates to a mutant plant of the Cucurbitaceae family comprising a modified CENH3 gene, which mutant plant, when crossed to a wild-type plant having 2n chromosomes produces progeny, at least 0.1% of which have n chromosomes. Preferably, the modified CENH3 gene comprises at least one mutation compared to an otherwise identical naturally occurring CENH3 gene, which at least one mutation gives rise to at least one nonconservative amino acid change in the Histone Fold Domain of the encoded modified CENH3 protein or to the occurrence of a premature stop codon in the encoded modified CENH3 protein. The invention further relates to a method for the production of haploid or doubled haploid plants and to the plants thus obtained.
