Abstract
The present invention relates to tomato plants that are resistant to pathogenic plants of the Orobanchaceae family, to methods for producing said plants and to the use thereof. The invention further relates to a method of controlling parasitic plants of the Orobanchaceae family, particularly O. aegyptiaca, in tomato crops and for securing tomato fruit production.
Claims19
A tomato cultivar exhibiting resistance to a parasitic plant of the genus Orobanche, wherein said resistance is controlled by a genetic determinant, said genetic determinant is represented by a single gene which shows a recessive inheritance, wherein said genetic determinant is obtained from tomato line ORT-10, deposited with NCIMB under accession number NCIMB 41586, further wherein said genetic determinant is in a homozygous state in said cultivar.
A hybrid tomato plant providing Orobanche resistance produced by crossing tomato plant line ORT-10, seeds of which were deposited with NCIMB under accession number NCIMB 41586, as a parent with another tomato plant line.
A method of producing an Orobanche resistant tomato cultivar comprising the steps of introgressing from a donor plant of tomato line ORT-10, deposited with NCIMB under accession number NCIMB 41586, comprising a genetic determinant directing or controlling expression of the Orobanche resistance phenotype into a recipient plant, which is susceptible to infections with the Orobanche parasite, by (a) crossing said donor plant with said recipient plant to obtain F1 progeny plants, (b) self fertilization of said F1 plants to obtain F2 progeny plants and/or backcrossing said F1 plants with said tomato line ORT-10 to obtain a progeny plant exhibiting the Orobanche resistance, and (c) screening for and selecting from the progeny plants a plant exhibiting an Orobanche resistant phenotype and, optionally, harvesting the resultant progeny seed.
