Indirect Selection for Seed Yield in Sacha-Inchi (Plukenetia volubilis) in Brazil

Breeding programs for improvement of sacha-inchi, Plukenetia volubilis L., generally aim to select individuals with greater seed yield since there is a strong correlation between and oil production. However, the manual removal husks evaluating this trait laborious costly, thereby discouraging breeding efforts. Accordingly, objective present study was estimate gains from indirect selection production in sacha-inchi progenies, focusing on maximizing efficiency programs. Genetic parameters along direct were estimated traits 12 open-pollinated progenies. Strong genetic correlations observed total number fruits (TNF), weight (TWF), seeds (TWS) per plant (r > 0.96). Notably, all three demonstrated high heritability (h2 0.81). Therefore, plants TNF TWF (Cuzco, Dos de Mayo, Shanao, Aucaloma, AM-7) can be used indirectly higher yields (GS% = 23%). gain dry index 42% at 23%, which corresponds 118 kg·ha−1. Future progenies facilitate TWS.
