Multi-environmental traits selection and farmer's participatory assessment of mean performance and stability of orange-fleshed sweet potato genotypes in Benin.

ABSTRACT: Regularly consuming orange-fleshed sweet potatoes (OFSP) is widely recognised as an effective way to treat vitamin A deficiency (VAD), particularly in low-income countries. Unfortunately, cultivars of OFSP are poorly disseminated in most countries in sub-Saharan Africa, where VAD is a major cause of blindness. This study was conducted to evaluate the effect of the genotype-environment interaction (GEI) on the performance and stability of the yield components of OFSP cultivars to trigger their adoption by farmers. Nine OFSP genotypes were evaluated through a multi-environment trial (MET) carried out in 14 environments and in a complete randomised block (RCB) design to select the best genotypes based on the multi-trait mean performance and stability index (MTMPS) and participatory variety se
