Quel. var. elaeoselini, P. eryngii (DC.:Fr.) Quel. var. tuoliensis C. J. Mou and P. nebrodensis (DC.:Fr.) Quel., which are not native in Japan, and P. ostreatus (Jacq.: Fr.) Kummer, which is native in Japan and the novel species obtained by the method and is also to provide a novel species of Pleurotus spp. carrying both a P. eryngii (DC.:Fr.) Quel. gene and a P. ostreatus (Jacq.: Fr.) Kummer gene by crossbreeding P. ostreatus (Jacq.: Fr.) Kummer with P. eryngii (DC.:Fr.) Quel. var. tuoliensis C. J. Mou, P. nebrodensis (DC.:Fr.) Quel. or P. eryngii (DC.:Fr.) Quel. var. ferulae Lanzi, thereby obtaining a strain capable of further crossbreeding with P. eryngii (DC.:Fr.) Quel., P. eryngii (DC.:Fr.) Quel. var. elaeoselini or the like.

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.

Further embodiments include methods of producing, selecting, and evaluating the responses of Ocimum basilicum plants or germplasm having tolerance or improved tolerance to Peronospora belbahrii infection; said plants comprised of at least one dominant allele and at least one recessive allele in the homozygous state that produce higher levels of tolerance to Peronospora belbahrii; seeds, plants, plant parts, methods for producing basil plants by crossing said basil plant with itself or with another basil plant, methods for producing sweet basil plants having higher tolerance to Peronospora belbahrii, plants and plant parts produced by those methods and methods for producing interspecific basil plants having tolerance to Peronospora belbahrii.

The present invention provides an interspecific Helianthus plant comprising a genetic determinant responsible for an indeterminate phenotype. Methods of making said plant are also provided.

Tomato plants exhibiting resistance to tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 are provided, together with methods of producing, identifying, or selecting plants or germplasm with a tomato chlorosis virus and Fusarium oxysporum f. sp. lycopersici race 2 resistance phenotype and lacking an undesirable cold sensitivity trait. Such plants include tomato plants comprising recombinant genomic regions conferring disease resistance. Compositions, including novel polymorphic markers for detecting plants comprising introgressed disease resistance alleles, are further provided.

The present disclosure relates to allopolyploid plants and hybrid allopolyploid plants having desirable traits, such as resistance to an abiotic or biotic stressor, which may be used as rootstock for cultivated tomato varieties. The disclosure further relates to composite plants comprising the allopolyploid plants described herein as the rootstock. The disclosure further relates to methods of producing allopolyploid plants and plant parts, and hybrid allopolyploid plants and plant parts.
