Agronomic performances of temporary immersion bioreactor-derived potato microtubers in a Peruvian low input cropping agriculture system

In Peru, potato cultivation represents 25% of the agricultural gross domestic product yet only 0.2% agamic seed used is from certified sources. The use temporary immersion bioreactors (TIB) has improved quality microtubers micropropagated along with savings in costs production. current study investigated agronomic performances Peruvian Canchan derived TIB (basic 1 and 2) under low-input agro-technology coastal zone Peru. Following 75 days growth, plants produced TIBs displayed slower vegetative growth than those conventional tubers. However, at harvest, these differences were no longer apparent as derived-basic 2 highest numbers tubers per plant. Although raised fresh mass tubers, significantly more propagules by regenerated basic micropropagation liquid media. These results demonstrate that much planting material (seed tubers) can be obtained field 1) commercial   Key words: Agronomic traits, micropropagation, microtuber, Solanum tuberosum L.,  bioreactors.
