Abstract: | Summary The availability of improved True Potato Seed (TPS) varieties for short and long photoperiod conditions has recently increased
the interest in the TPS technology. A summarized overview is presented of the TPS technology for potato tuber production,
TPS breeding and production. TPS competes successfully with clonal cultivars in Egypt and India. In other developing countries
higher yields and better adaptation are needed to make the TPS technology economically attractive; the case of TPS in Indonesia
is used to illustrate this. In industrialised countries, well-performing seed tuber programmes, productivity and legislative
restrictions are difficult to beat by TPS. However, the use of TPS can be economically attractive where disease pressure is
high. It is concluded that TPS has a place within potato systems where agroecological conditions for seed tuber systems and
steady supply of good quality tubers from a formal seed programme are most constrained. Further genetic improvement will increase
the areas where TPS provides better and cheaper planting material. |
