Parthenocarpic genetic elements derived from
The present invention relates to a method of producing a parthenocarpic, and optionally male sterile, tomato plant comprising introgressing into said plant a genetic region from Chromosome 4, 5 and/or 12 of S. habrochaites LYC4/78, a representative sample of seed of which was deposited on 13 Nov. 2007 with the NCIMB under Accession number 41517, wherein the genetic region from Chromosome 4 of S. habrochaites LYC4/78 includes at least one marker selected from Marker CD59, RFLP Marker CT229, and COS Marker T1068, and wherein the genetic region from Chromosome 5 of S. habrochaites LYC4/78 includes at least one marker selected from COS Marker T1181, RFLP Marker TG441 and/or RFLP Marker CD31(A).
1. A parthenocarpic and optionally male sterile Solanum lycopersicum tomato plant having fruits that are entirely seedless, or part thereof, obtained by a method comprising introgressing into a S. lycopersicum tomato plant a genetic region only from Chromosome 4 and/or 5 of Solanum habrochaites LYC4/78, of which a representative sample of seed of said S. habrochaites LYC4/78 was deposited Nov. 13, 2007, with the NCIMB under Accession Number 41517, wherein the genetic region from Chromosome 4 is between Markers CD59 and TG272 and includes marker CD59, wherein the genetic region from Chromosome 5 is between COS Marker T1181 and RFLP Marker CD31(A) and includes at least one marker selected from the group consisting of COS Marker T1181, RFLP Marker TG441 and RFLP Marker CD31(A), and wherein said parthenocarpic tomato plant is not S. lycopersicum cv. Moneymaker.
2. A parthenocarpic and optionally male sterile inbred Solanum lycopersicum tomato plant having fruits that are entirely seedless, or part thereof, obtained by a method comprising:
a) producing a parthenocarpic tomato plant according to claim 1 ;
b) crossing said parthenocarpic tomato plant with itself or another tomato plant to yield progeny tomato seed;
c) growing said progeny tomato seed to yield additional parthenocarpic tomato plants; and
d) repeating steps b) and c) from 0 to about 7 times to generate a parthenocarpic inbred Solanum lycopersicum tomato plant comprising a genetic region from Chromosome 4 of S. habrochaites LYC4/78 between markers CD59 and TG272 and/or a genetic region from Chromosome 5 of S. habrochaites LYC4/78 between COS marker T1181 and RFLP marker CD31(A);
wherein said inbred tomato plant is not S. lycopersicum cv. Moneymaker.
3. A hybrid Solanum lycopersicum tomato plant, or parts thereof, that exhibits a parthenocarpic and optionally male sterile phenotype, wherein said hybrid tomato plant is obtained by crossing a parthenocarpic inbred tomato plant of claim 2 with an inbred tomato plant that exhibits commercially desirable characteristics.
4. A parthenocarpic and optionally male sterile Solanum lycopersicum tomato plant according to claim 1 ,
wherein the genetic region from Chromosome 4 of S. habrochaites LYC4/78 further includes at least one marker selected from the group consisting of RFLP Marker CT229 and COS Marker T1068.
5. A tissue culture of regenerable cells of a tomato plant of claim 1 .
6. A tissue culture of regenerable cells of a tomato plant of claim 1 wherein said regenerable cells comprise cells or protoplasts isolated from a tissue selected from the group consisting of leaves, pollen, embryos, roots, root tips, anthers, flowers, fruits, stems and seeds.
7. The tomato plant or part thereof according to claim 1 , wherein the genetic region from Chromosome 4 of S. habrochaites LYC4/78 does not include markers TG272, TG264, TG62, T1405, and/or CT50.
8. The tomato plant or part thereof according to claim 1 , wherein the genetic region from Chromosome 5 of S. habrochaites LYC4/78 does not include RFLP Marker TG318 or markers downstream therefrom.
9. The tomato plant or part thereof according to claim 1 , wherein said parthenocarpic and optionally male sterile tomato plant is a cultivated S. lycopersicum plant.
