Hybrid melon variety 34-780 RZ

A melon plant designated 34-780 RZ, representative seed of which having been deposited under NCIMB Accession No. 42129.

A melon plant exhibiting a combination of traits comprising small leaves with erect to semi-erect petioles, a yellow ground color of the fruit skin, fruits that have a medium rate of change of fruit color from maturity to overmaturity, resistance to aphids (Aphis gossypii), intermediate resistance to powdery mildew Podosphaera xanthii (Px) race 1, race 2, race 5, intermediate resistance to powdery mildew Golovinomyces cichoracearum (Gc) race 1, and having genetic material for so exhibiting the combination of traits;

• wherein the genetic information is as contained in a plant, representative seed of which having been deposited under NCIMB Accession No. 42129.

A method for producing a seed of a 34-780 RZ-derived melon plant comprising (a) crossing a plant of melon variety 34-780 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42129, with a second melon plant, and (b) whereby seed of a 34-780 RZ-derived melon plant forms.

A method of introducing a desired trait into a parent plant of hybrid melon variety 34-780 RZ comprising:

• (a) crossing a parent plant of hybrid melon variety 34-780 RZ, representative seed of which having been deposited under NCIMB Accession No. NCIMB 42129 with a second melon plant that comprises the desired trait to produce F1 progeny;
• (b) selecting an F1 progeny that comprises the desired trait;
• (c) crossing the selected F1 progeny with said parent plant of melon variety 34-780 RZ, to produce backcross progeny and (d) selecting backcross progeny comprising the desired trait and the physiological and morphological characteristics of said parent plant of melon variety 34-780 RZ, when grown in the same environmental conditions.
