The reproductive growth intensity of micropropagated (MP) strawberry plants of cultivars Bounty, Jonsok and Senga Sengana, their three subsequent generations of runner plants (RP), two-year-old conventionally propagated runner (RP) plants, and micropropagated plants of different in vitro ages and origins were evaluated in two field experiments conducted in South Estonia in 1997 and 2001.
The following conclusions may be drawn on the basis of these experiments: 1. Of the three cultivars included in the experiment, cv. Jonsok gave the highest number of runner plants. 2. The micropropagated runner plant generations of cv. Senga Sengana and the two- year-old conventionally propagated plants did not show reliable difference in their runner plant production. 3. Reproduction rate was influenced rather by the age of the plantation than by the age of micropropagation material. 4. A three-year-old plantation is not suitable for collecting material for further propagation. 5. Younger mericlones produce plants with higher runner production rates than older ones.
