Methods for increasing hybrid seed production are provided. Increased hybrid seed production is achieved through higher outcrossing rates in cytoplasmic male sterile (CMS) lines of rice by introgressing the long stigma trait of Oryza longistaminata. CMS lines having higher outcrossing rates capable of high hybrid seed set are also provided.

The present invention relates to non-transgenic and transgenic plants, preferably crop plants, having biological activity of a haploid inducer and comprising a polynucleotide which comprises a nucleotide sequence encoding a centromer histone H3 (CENH3) protein, wherein the polynucleotide comprises at least one mutation causing an alteration of the amino acid sequence of the CENH3 protein, and to a part of the part. Further, the invention provides methods of generating the inducer plants, methods of generating haploid and double haploid plants using the inducer plants as well as methods of facilitating cytoplasm exchange.

The present disclosure provides Brassica oleracea plants exhibiting broad spectrum resistance to Xanthomonas campestris pv. campestris. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea var. capitata. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.

A wheat variety designated T16Y871, the plants and seeds and plant parts of wheat variety T16Y871, methods for producing a wheat plant produced by crossing the variety T16Y871 with itself or another wheat plant, and hybrid wheat seeds and plants produced by crossing the variety T16Y871 with another wheat line or plant, and the creation of variants by backcrossing, mutagenesis or transformation of variety T16Y871. Methods for producing other wheat varieties or breeding lines derived from wheat variety T16Y871 and wheat varieties or breeding lines produced by those methods are also provided.

The present invention provides methods and composition for preparing seeds that when cultivated produce pepper plants with seedless fruits. These plants may further be male sterile and contain a stable non-Peterson Cytoplasmic Male Sterility (CMS). The invention also provides essentially pure populations of seed that, when grown, produce pepper plants with seedless fruit. Methods are provided comprising crossing a stable non-Peterson CMS plant as a female parent with pepper lines displaying a parthenocarpy trait. The invention also includes the seeds produced by such a method. Methods for breeding and using seedless pepper plants for enhancing the production of fruit under suboptimal temperature conditions are also provided.

The present invention relates to a plant from the Capsicum family suitable for use as rootstock, capable of being obtained from the initial crossing of a Capsicum plant, preferably a C. annuum plant, with a Capsicum baccatum plant used as female parent, optionally followed by one or more additional crossing(s) with a Capsicum baccatum plant. Another subject of the present invention is a grafted plant constituted of a rootstock according to the invention and a graft. A further subject of the present invention is a seed, a cell or a part of a rootstock plant according to the invention. A final subject of the present invention is the use of a plant according to the invention as rootstock and a process for obtaining a grafted plant.

New plants were created from a new and efficient method of intergeneric hybridization between a plant from the group I. versicolor and Glebionis sp. as a female parent and a plant from the genus Argyranthemum as a male parent. The plants were created by rescuing an embryo from the cross-pollination of a plant from the group I. versicolor and Glebionis sp. as a female parent with an Argyranthemum male parent. The invention also describes a method for infecting hybrid plants with a virus and a viroid to modify plant phenotype. In addition to providing the intergeneric hybrid plants and parts thereof, the invention provides methods for making such plants and methods for creating other intergeneric hybrid plants and self plants from normally self-incompatible plants.
