Bottle gourd [Lagenaria siceraria (Mol.) Standl.], also known as calabash, is an edible, medical, container and grafting stock plant cultivated all over the tropics. Amazingly, high genetic variability exists in bottle gourd, especially in fruit size and shape, which can be round, oblate, pyriform, elongated curvilinear, dipper, slender straight, tubby, snake-like and more.
