Heterosis and Responses to Selection in Orange-Fleshed Sweetpotato (Ipomoea batatas L.) Improved Using Reciprocal Recurrent Selection.

ABSTRACT: Sweetpotato is a highly heterozygous hybrid, and populations of orange-fleshed sweetpotato (OFSP) have a considerable importance for food security and health. The objectives were to estimate heterosis increments and response to selection in three OFSP hybrid populations (H₁) developed in Peru for different product profiles after one reciprocal recurrent selection cycle, namely, H₁ for wide adaptation and earliness (O-WAE), H₁ for no sweetness after cooking (O-NSSP), and H₁ for high iron (O-HIFE). The H₁ populations were evaluated at two contrasting locations together with parents, foundation (parents in H₀), and two widely adapted checks. Additionally, O-WAE was tested under two environmental conditions of 90-day and a norma
