Genotype 3 environment interaction and selection for drought adaptation in sweetpotato (Ipomoea batatas [L.] Lam.) in Mozambique

Sweetpotato is grown throughout the year in Mozambique but drought affects storage root yield and biomass productivity. The objectives of this research were to estimate the impact of genotype × environment interactions (G × E) in sweetpotato and select genotypes based on drought indices such as geometric mean, percent yield reduction, drought sensitivity index …

Poster: Sweetpotato Grafting: New approach of vine conservation in dry areas

In the tropics, prolonged droughts damage farm saved stock plants leading to shortage in planting material at the start of the planting season. Despite wide adoption of orange fleshed sweetpotato (OFSP) its sensitivity to drought and poor vegetative growth brought grafting techniques for variety improvement. In this poster Mihiretu reports …

SASHA Brief 2013: Mitigando desastres em Moçambique

Mozambique experienced severe drought in Southern and Central regions affecting over 92,000 household. The international Potato Center (CIP) via Mozambique government request, developed disseminating strategy for the orange-fleshed sweetpotato (OFSP) in affected regions. This initiative aimed to provide the household with drought-resistant varieties, pro-vitamin A rich OFSP. Working closely with …

DEVELOPMENT OF FAST SCREENING METHODS TO IDENTIFY DROUGHT TOLERANT SWEETPOTATO

  Climate changes especially drought has adverse effects on sweetpotato. Planting materials/vines that survives in drought prone areas poses desirable tolerant trait. This presentation focuses on ongoing development of rapid screening methods for selecting drought tolerant lines. The proposed approach method starts with field trial establishment, physiological and agronomic analysis, …

SWEETPOTATO SCREENING FOR DROUGHT TOLERANCE AND HIGH BETA-CAROTENE CONTENT IN MOZAMBIQUE

  Small scale SP farming in Mozambique is rain dependent. These farmers rely on SP for carbohydrates and income generation. However, their yields are low subject to drought stress, pest and disease, poor soils and varieties.  Though SP are more drought tolerant compared to other crops, extended dry seasons adversely …

Evaluation of sweetpotato genotypes for drought resistance

Drought resistance

In this publication, we see that drought is a major environmental constraint to potato production in warm and hot tropics and for sweetpotato in the traditional cultivation areas. The problem of drought stress can be alleviated by manipulating cultural and management practices and by using adapted genotypes with drought resistance. …
