Methods for improving the yield of cucumber plants

The present invention relates to a plant of a cucumber breeding line having an introgression from cucumber accession PI 169383, a representative sample of seed of which has been deposited with the NCIMB, Aberdeen, Scotland under accession number NCIMB 41532 and depositors reference PI169383, wherein the introgression is an introgression on linkage group 4 associated with increased yield of the plants, wherein the plant exhibits an increased yield relative a plant of the cucumber breeding line lacking the introgression, and wherein the increased yield refers to a higher total fruit weight per plant.
