Obtention of microtubers and minitubers as pre basic seed in tree Peruvian potato cultivars
Journal Title: Biotecnología Vegetal - Year 2017, Vol 17, Issue 3
Abstract
In potato (Solanum tuberosum L.) seed certification programs, the use of in vitro plants, microtubers and minitubers as pre-basic seed are of great importance, especially in countries such as Peru, where there is a need to eradicate the informal production of the seed to promote new plantations. The present work had as objective to obtain of microtubers and minitubers as pre-basic seed in three Peruvian potato cultivars. When comparing the effect of both factors (method and cultivar) in the number of seeds per plant it was possible to state that with the exception of the cultivar ‘Capiro’, no differences were found between both methods of seed production for the rest of the cultivars. This result is very important since it shows that it is possible to use both methods of pre-basic seed production for cultivars ‘Canchan’ and ‘Papa3’. In the cultivar ‘Capiro’ a greater number of minitubers was achieved per plant, but its low fresh mass, which could prevent its use as a basic seed. Other studies are required to adjust the culture conditions to achieve better results in this cultivar.
