| Abstract:
The availability of a large collection of peach germplasm and the latest knowledge of character inheritance has allowed the individuation of several "potential parents" utilized for the realization of a "new peach genetic and varietal improvement program" started in Florence in 1983. The program's goal is the development of valuable cultivars of: white flesh canning peaches, white and yellow flesh canning nectarines, white flesh peaches and nectarines, ornamental and "double aptitude" peaches. F2 seedling are already available and the evaluation of the 52 isolated selections of F1 seedlings is already taking place. These selections provide us concrete possibilities in order to release in short time, several new cultivars: "white flesh canning peache" ("DOFI-84.334.015" selection is optimal); "white flesh peaches" ("DOFI-84.341.020" and "DOFI-84.342.002" selections are valuable); and especially the "white flesh nectarine", from which 20 studied selections fulfill the requirements for developing a new varietal assortment with a ripening period which includes the end of June ("DOFI-84.339.002" selection) and the end of September ("DOFI-87.405.036" selection). Final and more significant results are expected from the cross-breed combinations now being executed in which the seedlings are under careful observation. The third cross-breed generation (F3) forecasts the obtaining of new "canning nectarines" and is now being realized. | |
