AbstractThrough a great deal of researches, cultivation and cultivars classification of lotus varieties, the method of bud propagation is used in this study for the single-plant pedgree selection, the plot experiment and the feld demonstration experiment to breed a new lotus variety with high quality and disease resistance, Xingshuoulian 3. It grows short and small plants at 110 ~ 130 cm in height, thicker leaves at about 70 cm in diameter, early bud at the top, white primary root, and 6 ~ 7 main lotus roots in short cylindrical shape and with yellow white skin. It is early-mature with 100-day growth period, produces the whole lotus root at about 2.5 kg, good marketing, and yields fresh lotus root at 30.0 ~ 37.5 t per hm2. It is strong adaptable, and resistant to rotdisease and leaf spot disease. And it could be grown widely in the middle and lower reaches of Yangtze River in China.
