Abstract
Among the progenies of seedlings obtained by open and cross-pollination of standard cultivars, several semi-dwarf selections with the genotypes bu1 bu2 (Lammerts, 1945) recessive, and n (Monet, Salesses, 1975), partially dominant, have been identified.
The tree size of these selections is 30–50% smaller compared to standard cultivars.
The selections, used in the breeding program to breed semi-dwarf new varieties suitable for high density planting, are in order of ripening: IF 7010200 (J.H.Hale x Bonanza), IF 6910019 (Sentinel o.p.), IF 6910167 (Southland x Fairtime), IF 6910138 (Redhaven o.p.), IF 7310828 (F2 J.H.Hale x Bonanza), IF 6910242 (Southland x Summerset). The time of ripening varies from 10 days before to 43 days after Redhaven.
The following characters have been controlled: tree size, internode length and diameter of one year old twigs, leaf area, chlorophyll content, cell wall thickness, stomata number, together with the agronomical records.
The tree size of these selections is 30–50% smaller compared to standard cultivars.
