| Abstract:
Suitability of 14 genotypes for generative rootstocks production was investigated in this paper. In examined genotypes number of germinated seeds, total number of seedlings, number of seedlings suitable for grafting and number of produced scions in relation to number of stratified seeds was determined. Seedlings from all vineyard peach genotypes were grafted with cv. Suncrest in order to examine vigour and uniformity of scions. Considering total number of seeds, when rootstocks were genotypes I/6, II/1, XIX/23, XIX/28 and XIX/30, satisfied number of scions (over 40%) was obtained. Based on coefficient of variation, different degree of variability of investigated scion characteristics considering rootstocks were determined. Applied t-test showed that between all scion characteristics (height, diameter and brunch number) influenced by rootstocks, very significant differences are present. | |
