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.

The present invention relates to methods and compositions for identifying, selecting and/or producing a maize plant or plant part having increased fertility. A maize plant or plant part that has been identified, selected and/or produced by any of the methods of the present invention is also provided.

The present disclosure provides a method for selecting a plant comprising a functional restorer gene for maize S-type cytoplasmic male sterility comprising the steps of (a) screening a population of plants for at least one marker nucleic acid, wherein the marker nucleic acid comprises an allele linked to the functional restorer gene for maize S-type cytoplasmic male sterility; (b) detecting the marker nucleic acid; (c) identifying a plant comprising the marker nucleic acid; and (d) selecting the plant comprising the marker nucleic acid, wherein the plant comprising the marker nucleic acid further comprises the functional restorer gene for maize S-type cytoplasmic male sterility. The present disclosure also provides methods for restoring fertility in a progeny of an S-type cytoplasmic male sterile plant and methods for transferring an Rf3 gene into a progeny plant.

According to the invention, there is provided a novel hemp Cannabis cultivar which produces a skewed ratio of female plants. This invention thus relates to the seeds of hemp Cannabis cultivar of the invention, to the plants of hemp Cannabis cultivar of the invention, to plant parts of hemp Cannabis cultivar of the invention, to methods for producing a Cannabis cultivar by crossing the hemp Cannabis cultivar of the invention with another Cannabis cultivar, and to methods for producing a Cannabis cultivar containing in its genetic material one or more backcross conversion traits or transgenes and to the backcross conversion Cannabis plants and plant parts produced by those methods.

The present invention relates to a plant of the family Rubiaceae, in particular to a Pentas lanceolata plant having a novel trailing growth habit phenotype. Methods of obtaining, growing and propagating a plant of the invention and uses thereof are also provided. The invention further relates to pollen, seed and sexual as well as asexual progeny of such plants.

The problem of providing a technology that converts a Brassica rapa plant having self-incompatibility to having self-compatibility is addressed. The problem is solved by causing a pollen factor (SP11) to be inactive at a self-incompatibility gene locus for a Brassica rapa plant, while maintaining the inverted repeat sequence (SMI) on a class I dominant S haplotype.

The invention provides containers comprising at least one or at least two seedlings of at least one seedless watermelon variety and at least one seedling of a seeded pollenizer watermelon variety. The present invention further provides methods for producing watermelon fruit, optionally over an extended season, comprising planting together in a container at least one seedling of a seedless watermelon variety and at least one seedling of a seeded pollenizer watermelon variety, wherein the at least one seedling of a seeded pollenizer watermelon variety produces male flowers in sufficient time to pollenize female flowers of the at least one seedling of a seedless watermelon variety.

Described herein are methods for producing guayule seeds, guayule plants, and products generated therefrom. More specifically, the disclosure provides methods for the production of viable seeds from apomictic guayule plants, seeds produced by such methods, plants grown from such seeds, plant parts, biomass, and biomaterials derived therefrom.

The invention relates to Spathiphyllum plants having reduced pollen content, obtained by a method, comprising the steps of providing a tetraploid Spathiphyllum parent and a diploid Spathiphyllum parent, and crossing these tetraploid and diploid parents to produce the Spathiphyllum plants having reduced pollen content. The invention also relates to a method for producing Spathiphyllum plants having reduced pollen content.

According to the invention, there is provided a novel hemp Cannabis cultivar which produces a skewed ratio of female plants. This invention thus relates to the seeds of hemp Cannabis cultivar of the invention, to the plants of hemp Cannabis cultivar of the invention, to plant parts of hemp Cannabis cultivar of the invention, to methods for producing a Cannabis cultivar by crossing the hemp Cannabis cultivar of the invention with another Cannabis cultivar, and to methods for producing a Cannabis cultivar containing in its genetic material one or more backcross conversion traits or transgenes and to the backcross conversion Cannabis plants and plant parts produced by those methods.
