Potato (Solanum tuberosum L.) is an important food and cash crop in Rwanda. The objective of this study was to identify suitable potato varieties for growing under aeroponics production systems. Four commercial potato varieties - Kirundo, CIP 393371-58, Kinigi and Kigega - were evaluated in an aeroponics green house at Rwanda Agriculture Board RAB-Musanze station, from January to May 2016. The study consisted of 30 plantlets per m2. The experimental design was a split plot design with four replications. In an enclosed environment, the supply of nitrogen (N), phosphorus (P), magnesium (Mg), calcium (Ca), and other nutrients to plants were done by use of a mist nebulizer. The results showed there was an increased vegetative cycle in CIP 393371-58 (with 8.2 cm plant height and 3.3 nodes) followed by Kirundo (1 cm plant height and 1.5 nodes ), Kinigi (27.1 cm plant height and 6.2 nodes) and Kigega (56.4 cm height and 19.3 nodes), respectively. The maturity period of CIP 393371-58 was 70 days. This was earlier than Kinigi (77 days), Kirundo (112 days) and Kigega (156 days), respectively. The mini-tuber per plant production was also higher in CIP 393371-58 (41), followed by Kinigi (36), Kirundo (28) and Kigega (7), respectively. The data showed that the CIP 393371-58 variety was better adapted to an aeroponics environment than were Kinigi, Kirundo, and Kigega, respectively.
