The objective of this research was to determine number, crown diameter and root nodules of runner tips produced by micropropagated and multiplied strawberry stock plants at different planting times. The experiment was conducted between October, 2008 and April, 2009, with cultivars INIA-Arazá, INIA-Guenoa and INIA-Yvapitá and ten planting times, at 37; 40; 46; 51; 58; 64; 67; 75 and 87 days after planting the micropropagated stock plants, respectively. Number of runner tips decreased linearly by delaying planting time of stock plants, while crown diameter and number of root nodules were not affected. Higher number of runner tips was produced by micropropagated plants and INIA-Arazá was the most prolific cultivar. Multiplying stock plants may be a new propagation method than can be used for reducing the number of micropropagated stock plants required for the production of strawberry commercial plug transplants.
