Relationship between the performance of parental inbred lines and hybrids for food-feed traits in maize (Zea mays L.) in Ethiopia

► Trends in variability in inbreds and hybrids, association between food-fodder traits and GCA of inbred lines assessed. ► We found higher genotypic variation for food-feed traits and association between traits had similar trend in hybrids and inbreds. ► GCA, indicative of the additive gene effect was important for most stover fodder quality traits. ► The relationship of line per se with hybrid performance and GCA were positive and significant for most stover fodder quality traits. ► Selection of inbred lines at early stage of inbred line development is the best strategy for the development of food-feed type of inbred lines.
