Fig. 3

Schematic plan of the seed orchard “Graeff” (not to scale). The seed orchard contains 6 rows with 20 grafted plants each (= 120 plants). Each plant is represented by a dot, clone name (A-N) is given on top of the dot. Please note: clones of the same name and colour in “Gottesgabe” and “Graeff” are not genetically identical. Clones C, G and H did not flower and are shown in white and light grey. For the trees used for seed harvest, pie charts show the share of different pollen donors in the offspring of the respective seed tree. Colours for the pollen donors used in the pie charts are in correspondence with the colours used for the adult clones of the seed orchard. White colour in the pie charts represents the share of pollen from unknown fathers. Pollen from selfing events is shown in the same colour as the respective seed tree. Only one offspring individual from clone D in row 1 was analysed. Clone N in row 4 represents the potential rootstock genotype
