The present invention relates to the use of trehalose, and/or a derivative thereof, as a supplement to a culture medium for culturing hybrid plant embryos in in vitro embryo rescue. The addition of trehalose, and/or a derivative thereof, to the culture medium significantly increased the survival rate of the hybrid plant embryos.

The present invention relates to materials and methods for creating and maintaining a cereal plant line for the production of a hybrid cereal plant, that include for example, and not limitation, using the BLue Aleurone (BLA) system.

The invention relates to a lettuce plant (Lactuca sativa L.) which may comprise a resistance allele which confers a broad spectrum resistance to Bremia lactucae, wherein the resistance allele is located on linkage group 9, and which resistance allele is as found in the genome of plants grown from seeds of which a representative sample was deposited under accession number NCIMB 42141. The invention further provides seeds, progeny, propagation material and food products from the plant.

An object of the present invention is to provide an F1 hybrid or a portion thereof, and use of the F1 hybrid or a portion thereof. The F1 hybrid of the present invention is an F1 hybrid between Nicotiana umbratica and Nicotiana kawakamii.

The present disclosure provides Capsicum annuum BCMS plants exhibiting uniform female fertility. Such plants comprise novel introgressed genomic regions associated with uniform female fertility from Capsicum annuum on chromosome 6. In certain aspects, compositions and methods for producing, breeding, identifying, and selecting plants or germplasm with a uniform female fertility phenotype are provided.

The present disclosure provides Capsicum annuum BCMS plants comprising a male fertility restoration locus. Such plants comprise novel introgressed genomic regions associated with male fertility from Capsicum annuum on chromosome 6. In certain aspects, compositions and methods for producing, breeding, identifying, and selecting plants or germplasm with a male fertility phenotype are provided.

An object of the present invention is to provide an F1 hybrid or a portion thereof, and use of the F1 hybrid or a portion thereof. The F1 hybrid of the present invention is an F1 hybrid between Nicotiana umbratica and Nicotiana kawakamii.

The present disclosure provides cultivated tomato plants exhibiting increased resistance to Mi-1 resistance-breaking root-knot nematodes. Such plants comprise novel recombinant chromosomal segments comprising alleles associated with disease resistance from Solanum pimpinellifolium on chromosome 1 and/or chromosome 6. In certain aspects, compositions and methods for producing, breeding, detecting, and selecting plants or germplasm with an increased disease resistance phenotype are provided.

The invention relates to the production of graft-mediated hybrid monocotyledonous plants. Methods for the production of such plants are disclosed herein.

The presently disclosed subject matter relates to using a haploid inducing line (whether existing or created) and transforming the haploid line so that it encodes cellular machinery capable of editing genes. The transformed haploid inducing line is used as a parent in a cross between two plants. During pollination, the parental gametes fuse to form an embryo; and the gene editing machinery is also delivered to the embryo at this time. During embryonic development, one set of parental chromosomes are lost, and the gene editing machinery operates on the remaining set of chromosomes. Thus, at least one haploid progeny with edited genes is produced from the cross. The disclosure is also directed to methods of testing an edited haploid plant progeny for the presence of a first plant's genomic material.
