Eight selected potato entries were evaluated for their performance in rapid multiplication technique. The entries 2.21.6.2, 380241.17 and the check variety Igorota had the most vigorous growth among the entries. Furthermore, Igorota gave the highest number of stem cuttings produced in three months with 152 stem cuttings/25 mother plants. It was followed by the entries 676070 and 380241.17 with 100 and 97 stem cuttings, respectively. Other entries (2.21.6.2, 5.19.2.2., 573275, Granola and Ganza) produced stem cuttings from 45 to 86 stem. Significant differences were obtained on tuber yield of the different entries under greenhouse. The entries 5.19.2.2 and 676070 had the highest number of tubers with 30 and 27 per sq m, respectively. The lowest were from entries Igorota, 573275 and 2.21.6.2 with tubers ranging from 18 to 23 pieces per sq m.
