FIELD PERFORMACE OF ‘SENGA SENGANA’ STRAWBERRY PLANTS (FRAGARIA × ANANASSA DUCH.) OBTAINED BY RUNNERS AND IN VITRO THROUGH AXILLARY AND ADVENTITIOUS SHOOTS
Wojciech Litwińczuk
ABSTRACT
Strawberry plants of ‘Senga Sengana’ cv. obtained in vitro from axillary (K-V0) and adventitious (P-V0) shoots were compared with their runner progeny (K-V1 and P-V1, respectively) and with standard runner (S, control) plants under field conditions. No differences were found in leaf shape and colour. In the planting year, in vitro obtained plants, both ‘K-V0’ and ‘P-V0’, developed significantly more crowns and runners while compared to other groups. Such differences, especially in runners’ number were not observed in the next two years. Flowering behaviour was appreciably influenced by propagation method. In the planting year, all in vitro propagated plants and about 80% their runner progeny flowered contrary to control (the only 3% plants). Every year ‘V0’ plants developed significantly more inflorescences than other studied groups. Plants obtained in vitro produced bigger fruits and higher yield than other groups in the first two years. However, a
