Morphological variation and heritability studies of Lagenaria siceraria landraces from northern KwaZulu-Natal, South Africa

Abstract: Lagenaria siceraria (Molina) Standley belongs to the Cucurbitaceae family. Its nutritious tender shoots, fruits, and seeds are widely consumed in rural communities as leafy vegetables. However, studies on variation and heritability of its agronomic traits are lacking. This study aimed to c...
