Mateus Rodriguez, J.Haan, Stef deRodríguez Delfin, A.[Genotype by environment effects on potato mini-tuber seed production in an aeroponics system.]Genotype by environment effects on potato mini-tuber seed production in an aeroponics system.

Farmer seed systems are considered pivotal to adaptation to climate change and the on-farm conservation of agrobiodiversity in centers of crop origin. To better understand their distinct role, we conducted a multipronged analysis of potato seed exchange networks in Peru's central Andes distinguis...

Purpose – Potato is a major food staple in Africa, but its production is constrained by poor quality of seed. A recent private–public partnership in Tanzania resulted in introduction of new higher yielding varieties. The purpose of this paper is to examine smallholder farmers’ motivations to inve...

Bacterial wilt, caused by Ralstonia solanacearum, is emerging as a major threat to potato production in Ethiopia, reaching epidemic proportions in the Chencha district recently, with a prevalence of 97% of potato fields in 2015. The recent disease outbreak in the district coincided with a signifi...

Ali, S.Kadian, M.S.Ortiz, O.Singh, B.P.Chandla, V.K.Akhtar, M.[Degeneration of potato seed in Meghalaya and Nagaland States in North-Eastern hills of India.]Degeneration of potato seed in Meghalaya and Nagaland States in North-Eastern hills of India.

Potato yields in sub-Saharan Africa remain very low compared with those of developed countries. Yet potato is major food staple and source of income to the predominantly smallholder growing households in the tropical highlands of this region. A major cause of the low potato yields is the use of p...
