Abstract: ‘Kunyu 2’is a new cultivar developed through systematic selection from the Amorphophallus spp. population. Two- to three-year-old plants reach a height of 65-145 cm. The interior of the corm is pink,with a rough skin and a prominent umbilical scar. The petiole surface is smooth,with a green base color featuring light green stripes and patches. As the plant matures,the base color of the petiole lightens,transitioning from light green to white. The growth period is approximately 163 days,with an average yield of 45 180 kg · hm^-2. This cultivar exhibits uniform plant architecture,exceptional lodging resistance,strong waterlogging tolerance,moderate resistance to soft rot,and high resistance to sclerotium rot. It is suitable for field cultivation in Dehong,Xishuangbanna,Pu’er,Lincang,Baoshan,and dry-hot valleys of Yunnan Province,as well as greenhouse cultivation in other regions.
