This book explores the behavior of Orange flesh Sweet potato yields and β- Carotene content in terms of stability in different Agro ecologies.
Its potential in alleviating vitamin A deficiency cannot be realized unless the cultivars exhibit good performance and stability in wider environment.
Multi location field trials involving 12 orange- fleshed sweet potato varieties were conducted at six different agro-ecologies (altitude range from 495 and 1798 meters above sea level) Tanzania.
Results showed that genotype and environment has influenced on β- carotene content and yields of sweet potato roots.
Sweet potato plants tend to accumulate more β- carotene in high altitude.
Utilization of sweet potato is mainly for direct human consumption, sale and animal feed in Tanzania.
Consumers ‘prefer varieties with high dry matter content.
