| Abstract:
Microshoots of three cultivars (Jonsok, Bounty, Senga Sengana) were intro-duced into tissue culture in 4 different years (1996, 1997, 1998 and 2000). Plant mate-rial was cultivated either on high salt (MS) or on low salt (M) concentration medium. MS medium promoted active proliferation, but the shoots remained too short for rooting. On M medium the proliferation rate was lower, but shoots elongated enough for successful rooting. The proliferation rate depended more on genotype than on the age of the mericlone. Micropropagated (MP) plants (tissue culture establishment year 1996, 1997, 1998 and 2000) and origin (EVIKA, Sweden and OÜ Mikrotaim) were evaluated in a field experiment from 2001 to 2003. Younger mericlones where charac-terized by a higher runner production rate than the older ones. Significantly higher yield compared to the control was obtained on Swedish mericlones of ‘Senga Sen-gana’ and ‘Bounty’. The age of the mericlone did not affect the yield, the weight of berries or the marketable yield. | |
