Genetic analysis and heterotic potential of onion (Allium cepa L.) for some physiological and agronomic traits under rainy-season cultivation
Onion ( Allium cepa L.) is the second most commonly produced and consumed vegetable worldwide. In West Africa, high heat and moisture are key constraints for onion productivity during the rainy-season. This study aimed to assess the combining ability, heterosis, and genetic variability of five onion genotypes a...
