Evalation of the Novel Bred Persian Walnut Genotypes

The Persian walnut (Juglans regia L.) is the most important shell fruit species in Hungary. A double selected Persian walnut population was established to select some novel bred genotypes. The examined genotypes originated from the following combinations: ’Milotai 10’ x ’Pedro’, ’Pedro’ x ’Alsószentiváni 117’, ’Alsószentiváni 117 x Pedro’ as well as selection form the local population. Significant differences in blooming time were found. All genotypes reached 32 mm in fruit diameter. Most of the fruit weight of the selected genotypes exceeded the results of ’Alsószentiváni 117’. Only two genotypes reached 50% in kernel rate. 11 genotypes reached 70% in creaking rate. Based on the results three genotypes (tree no. V/2/28-30, tree no. V/3/30-31 and tree no. BD6) were found, which had excellent values.
