Abstract: Disclosed is a method for the production of a plant of the Cucurbitaceae family by mutating seeds to induce a mutation of 1-aminocyclopropane-1-carboxylate synthase 8 (ACS8) and growing a plant from the mutated seed, with the plant having a androecy or androecious tendency.

Abstract: Plants of the Cucurbitaceae family and seeds of such plants with an androecious phenotype, whereas this sexual type is not natural in the plants, and the use of the plants and of the plant seeds of the invention. Moreover, the nucleic acid sequence responsible for androecy in the plants of the invention and on the polypeptide encoded by the nucleic acid sequence. Finally, methods of identifying the plants and the seeds.

Abstract: A genetic system for controlling the type of floral development of a dicotyledon plant, includes the combination of two genetic control elements, respectively: a first genetic control element (A/a) present in a dicotyledon plant, in the form of a dominant allele (A), and a recessive allele (a), and a second genetic control element (G/g) present in a dicotyledon plant, in the form of a dominant allele (G), and a recessive allele (g), provided that the first genetic control element has been artificially inserted into the dicotyledon plant. This system enables the sex of the flowers of dicotyledon plants to be controlled and/or modified.

Abstract: The present invention relates to a combination of two genetic elements for controlling the development of the floral type of a dicotyledonous plant, said combination comprising, respectively: a first genetic control element (A/a) present in a dicotyledonous plant, in the form of a dominant allele (A), and of a recessive allele (a), and a second genetic control element (G/g) present in a dicotyledonous plant, in the form of a dominant allele (G), and of a recessive allele (g), it being understood that at least the second genetic control element was introduced artificially into said dicotyledonous plant. The above combination makes it possible to control and/or modify the sex of the flowers of dicotyledonous plants.
