Genetic evaluation of sweet potato vine genotypes

摘要：

Introduction Sweet potato vines (ipomea batatas) have been reported to be an important source of crude protein (19.5/CP) with digestibility of 80％ (Irungu et al.,2004).According to Irungu the vines significantly improved intake in sheep (P ＜ 0.01) and stimulated digestion of low protein forages.The sweet potato vines therefore can form a major source of nutrients to livestock.They adapted well to wide environmental conditions and require low soil fertilizer,and have few pest & disease infection.The objective of this study was to identify,evaluate and select genotypes with traits of high dry matter content,crude protein (CP),vigorous morphological characteristics,drought tolerance and resistance to pests and diseases.
