Trials to study the production of planting materials from true potato seed (TPS) using both transplants and seedling tubers were promising. Transplants gave mean fresh tuber yields of 26.8 t/ha during 1992/93 and 21.7 t/ha in 1993/94, which compared well with the yield of clonal seed tubers of 20.5 t/ha. TPS raised in nursery beds of 3m produced many seedling tubers, averaging 224 m and 119 m during 1992/93 and 225 m in 1994, with mean tuber weights of 20 g, 27 g and 23 g. Trials to study the consistent decline in fresh tuber yields as the number of generations increased. Yields of TPS in the third and fourth generations were similar to altitudes showed that seed tubers derived from TPS had mean yields of 24.6 t/ha, which were similar to those of the established varieties that yielded 26.2 t/ha.
