EFFECT OF PARENT’S PLUM CULTIVARS ON THE OPTICAL DENSITY OF ANTHOCYANINS IN THE FRUIT SKIN OF F₁ GENERATION

The optical density of the fruit skin anthocyanins in the plum hybrid seedlings of the F₁ generation derived from the three combinations of crossing was studied: Stanley x President, Stanley x Prunus domestica L. cv.
Pozegaca, and Stanley x Ersinger Frühzwetsche, as well as of their parents: Stanley, Pozegaca, President and Ersinger Frühzwetsche.
These investigations indicated that there existed significant variation of the anthocyanins optical density within the same combination of crossing of hybrids with their parents.
In addition to this, the following conclusions may be inferred; the increase of blue skin colour results in the increase of optical density; seedlings having yellow or rose fruit skin colour had low optical density; the seedlings (56,2%) with the optical density being the same or similar to that of their parents predominated; the optical density was higher in 36,4% and lower in only 7,3% of the plum hybrid seedlings investigated.
