Trials of runner cuttings at two different times were carried out for propagation of runner plants of strawberry cultivar 'Asukarubi' on a bench without temporary planting. Effects of runner cutting on the NO3-N density in leaf stalks of propagated runner plants were not clear. The runner plants' leaf stalks were shorter, the top-root ratio was lower, and the roots were heavier when the runners were cut during propagation. Furthermore, when the cutting was done earlier, the leaf stalks were shorter and the top-root ratio was smaller. The number of runner plants with crown diameter greater than 5 mm was the almost same irrespective of runner cutting, although runner cutting reduced the total number of propagated runner plants. The fruit yield was higher in the runner-cutting treatments than in no cutting treatment in forced culture. The earlier the runners were cut, the higher the fruit yield.
