Abstract

The botanical or sexual seed of potato that is extracted from the fruit or “mamón” of the potato plant (Photo 1), is presented as a technological alternative to obtain quality tubers-seeds at a lower cost. In addition, it allows the introduction, evaluation and selection of materials (progenies) using this methodology of multiplication of potato tubers-seed from botanical seed that is easy to follow by interested producers, and with the accompaniment of technicians knowledgeable on the subject.

This seed is inexpensive, can be easily transported, and only 100-150 grams are required to plant one hectare of land, compared to the 2 or 3 tons of seed tubers required when using asexual propagation. This technology can gain acceptance among farmers for technical and management reasons, taking into account the experiences obtained. Likewise, it is important to point out that the tubers used for sowing by traditional method represent an important volume of food that is being buried in the field, when they could be destined for consumption; The 2 tons of seed tuber that are destined to plant 1 hectare are enough to cover the demand of 172 Venezuelans for a year, if we estimate the consumption of potatoes per person per month between 0.97 and 1 kilo.

This technology is seen as an appropriate option in tropical climates, such is the case of the state of Táchira. One of the main advantages of the sexual seed of the potato, as an alternative for the propagation of the crop, is the flexibility it offers through different forms of use in different agroecological conditions; In addition, it does not require sophisticated storage facilities (which are necessary to maintain seed tubers) and can be kept for several years without losing viability.
