摘要： The present invention relates to a mutant plant of the Cucurbitaceae family comprising a modified CENP-C 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. The modification comprises for example a mutation in the CENP-C gene that leads to the occurrence of a premature stop codon or to a non-conservative amino acid change in the C-terminal region of the encoded protein. The plant is for example a Cucumis sativus plant and the modified CENP-C gene encodes a modified CENP-C protein that comprises at least one not-tolerated amino acid change or a premature stop codon in the C-terminal region, when compared to the CENP-C protein of SEQ ID No:1, in particular a mutation selected from E674K and S650N. The plant may also be a Cucumis melo plant wherein the modified CENP-C gene encodes a modified CENP-C protein that comprises at least one not-tolerated amino acid change or a premature stop codon in the C-terminal region, when compared to the CENP-C protein of SEQ ID No:2.

摘要： The present invention relates to non-transgenic and transgenic plants, preferably crop plants, comprising at least one mutation of the KINTEOCHORE NULL2 (KNL2) protein, especially a mutation causing a substitution of an amino acid within the KNL2 protein, preferably within the C-terminal region of the KNL2 protein, which preferably have the biological activity of a haploid inducer. Further, the present invention provides methods of generating the plants of the present invention and haploid and double haploid plants obtainable by crossing the plants of the present invention with wildtype plants as well as methods of facilitating cytoplasm exchange.

摘要： The present invention relates to a method for the production of a set of seeds which are genetically identical to the male gametes from which they arise, comprising placing a limited number of paternal gametes that have the form of tetrads or dyads on the stigma of a flower to fertilize maternal egg cells to obtain a number of zygotes and inducing the loss of maternal chromosomes from the zygotes to obtain a seed set containing a limited number of seeds in which the maternal chromosomes are absent. Suitably, the paternal gametes that have the form of tetrads or dyads are the result of interference with microspore tetrad separation. In a preferred embodiment, the father plant exhibits suppression of chromosome recombination. The invention further relates to a set of seeds containing a limited number of seeds in which the maternal chromosomes are absent, which set is composed of pairs of genetically complementary seeds which when crossed result in essentially the same hybrid, and which seed set is obtainable by the method.

摘要： An object of the present invention is to provide a method for efficiently producing polyploids in para rubber trees that are extremely useful for breeding new varieties. The method of the present invention is characterized by carrying out colchicine treatment on para rubber tree (Hevea brasiliensis) seeds after rooting. In the present invention, the seeds are preferably seeds that have rooted but have not yet germinated. In addition, colchicine treatment is preferably carried out by allowing the seeds to contact a colchicine solution having a colchicine concentration of 400 ppm to 800 ppm.

摘要： Clonal embryos or seeds produced by conversion of apomeiotic gametes into clonal embryos or seeds. Clonal embryos or seeds are produced by crossing a
MiMe plant, as either a female or male, with an appropriate plant which induces genome elimination (genome eliminator, GE).
MiMe plants are those in which meiosis is totally replaced by mitosis. In specific embodiments
MiMe plants are
MiMe-1 plants or
MIME -2 plants. In specific embodiments
MiMe plants are mutant plants. In a more specific embodiment, the genome eliminator is a haploid inducer exhibiting directed genome elimination of its own genome.
