Abstract
A field trials with cvs. Lonja, Nizija and Jugoslavija, each of them with two variants: „certified seed“ and control „uncertified home produced seed“ were conducted from 1986 to 1987 and from 1988 to 1991 near Ljubljana to determine the effect of maintaining selection and seed technology on the yield of some wheat cultivars. Both seed variants were treated with the same fungicide and seeded 600 seed/m². During the growth period herbicides and two N treatments were performed, but no pest and disease protection was used. Results showed significant (P < 0,05) effect of maintaining selection and seed technology on the yield. Average increasing of yield for three cultivars was 8,85%, but only for cv. Lonja the difference was statistically significant - the effect of maintaining selection and seed technology was 16,7% or 940 kg/ha. For other two cultivars, Nizija and Jugoslavija showed the significant greatest yield in 4 years average (6.570kg/ha).
