Popis: The main objective of this research was to determine fruit yield of strawberry ( Fragaria x ananassa ) stock plants in a cropping system after producing runner tips and plug plants. Micropropagated stock plants were planted in a soilless growing system. Runner tips bearing at least one visible root nodule were harvested at 43, 66 and 87 days after planting, rooted and planted as multiplied stock plants for producing plug plants. Treatments consisted of micropropagated stock plants of cultivars INIA Araza, INIA Guenoa and INIA Yvapita, planted on October 1 st , 2008 (T1); multiplied stock plants planted on November 28 th (T2) and on December 21 st , 2008 (T3), and on January, 10 th , 2009 (T4). On May 22 nd , 2009, stock plants were defoliated and plug plants of the same cultivars were planted as control for fruit production. Early fruit yield and number of fruits were higher on stock plants, but fresh fruit yield was higher on control plants. Total fruit yield and number were higher on stock plants of ‘INIA Araza’ and ‘INIA Guenoa’. We concluded that strawberry stock plants reach higher early and total fresh fruit yield than plug transplants in the second cropping year after producing runner tips in a soilless growing system. Therefore, plants should not be discarded after the production of runner tips.
