Yield of five potato varieties in Temporary Immersion Bioreactors (TIB)

The potato (Solanum tuberosum L.) is important as both a food and a source of economic activity in Peru. However, potato production is limited by seed quality and other biotic and abiotic factors. We explore a new alternative method for producing prebasic seeds of Peruvian potato varieties known as...
