The invention relates to a modified PIN4 gene, the wild type of which is as identified in SEQ ID No. 1, encoding the protein of SEQ ID No. 5, or the wild type of which encodes a protein that has a sequence similarity of at least 80% to SEQ ID No. 5, which modified PIN4 gene encodes a protein that comprises an amino acid change as a result of the modification, and which modified protein is capable of inducing parthenocarpic fruit set when present in a plant. The invention also relates to plants and fruits that carry the gene. Such plants are capable of parthenocarpic fruit set and the fruits do not contain seeds. The invention further relates to use of the gene in breeding and producing plants capable of parthenocarpic fruit set.

The present invention relates to aplant which carries QTL1 in its genome that leads to resistance against thespecies complex, which QTL1 is located between flanking marker sequences SEQ ID No. 1 and SEQ ID No. 2 and can be identified by and is in particular linked to one or more markers selected from the group consisting of SEQ ID No. 3, SEQ ID No. 4, SEQ ID No. 5, SEQ ID No. 6, SEQ ID No. 7, SEQ ID No. 8, SEQ ID No. 9, SEQ ID No. 10, SEQ ID No. 11, and SEQ ID No. 12, or combinations thereof. In a further embodiment, theplant further comprises anotherresistance conferring QTL, which combination of QTLs leads to an improved level of resistance to thespecies complex when compared to a plant in which only the other QTL is present.
