Abstract

The present invention relates to an eggplant, in particular a Solanum melongena plant, comprising a genetic determinant, which when present confers a reduced number of trichomes on vegetative plant parts, and which is as found in plants grown from seed of which representative samples were deposited under NCIMB accession numbers NCIMB 41756 and NCIMB 42013. When the genetic determinant is homozygously present the number of trichomes is strongly reduced.

First claim

The invention claimed is:

1. An eggplant of the species Solanum melongena L., wherein leaf blades of the mature leaves of the eggplant have less than 20 trichomes per square centimeter, representative seed of which having been deposited under accession number NCIMB 41756 or NCIMB 42013.

2. A method of producing an eggplant of the species Solanum melongena L., wherein leaf blades of the mature leaves of the Solanum melongena L. plant have less than 20 trichomes per square centimeter, comprising:
crossing an eggplant, representative seed of which having been deposited as NCIMB 41756 or NCIMB 42013, with another eggplant and selecting in the F1 of the cross for plants of which the leaf blades of the mature leaves have less than 20 trichomes per square centimeter;
crossing an eggplant, representative seed of which having been deposited as NCIMB 41756 or NCIMB 42013, with another eggplant to obtain an F1, selfing the resulting F1 for obtaining F2 plants, and selecting in the F2 for plants of which the leaf blades of the mature leaves have less than 20 trichomes per square centimeter;
or crossing an eggplant, representative seed of which having been deposited as NCIMB 41756 or NCIMB 42013 with another eggplant to obtain an F1, backcrossing the resulting F1 with an eggplant , representative seed of which having been deposited as NCIMB 41756 or NCIMB 42013, obtaining F2 plants from the backcross, and selecting F2 plants wherein the leaf blades of the mature leaves have less than 20 trichomes per square centimeter, and optionally performing one or more rounds of selfing or backcrossing and subsequently selecting for plants wherein the leaf blades of the mature leaves have less than 20 trichomes per square centimeter.

3. The eggplant as claimed in claim 1 , wherein leaf blades of the mature leaves of the eggplant have less than 10 trichomes per square centimeter, less than 5 trichomes per square centimeter, or 0 trichomes per square centimeter.

4. A seed capable of growing into the eggplant of claim 1 .

5. A propagation material capable of growing into the plant of claim 1 .

6. The propagation material of claim 5 , wherein the propagation material is a microspore, pollen, ovary, ovule, embryo, embryo sac, egg cell, cutting, root, stem, cell, protoplast, leaf, cotyledon, hypocotyl, meristematic cell, root, root tip, microspore, anther, flower, seed, stem or a part thereof.

7. A tissue culture of the propagation material of claim 5 .

8. An eggplant fruit or a food product comprising said fruit, harvested from the eggplant of claim 1 .

9. A method of developing an eggplant of the species Solanum melongena L. wherein leaf blades of the mature leaves of the eggplant have less than 20 trichomes per square centimeter, comprising
a) crossing the eggplant of claim 1 with another plant;
b) selfing the resulting F1 for obtaining F2 plants;
c) selecting plants of which the leaf blades of the mature leaves have less than 20 trichomes per square centimeter in the F2; and
d) optionally performing one or more additional rounds of selfing or backcrossing, and subsequently selecting, for a plant of which the leaf blades of the mature leaves comprise/show less than 20 trichomes per square centimeter.

10. An F1 seed or F1 progeny plant produced by crossing the plant of claim 1 with a different Solanum melongena plant.
