绵粉一号是一个高淀粉甘薯新品种。由于其突出的高烘干率（３９．５％）和高出粉率（２９．３％），问世之后，除作为品种应用于生产之外，许多育种者纷纷作为亲本材料加以利用。经过近１０年的应用证明，绵粉一号确是一个优良的育种亲本材料。主要表现在：１．后代块根３个主要性状（鲜薯重、薯干重、烘干率）的一般配合力均高，特殊配合力方差也大。２．后代材料平均烘干率高，鲜薯与烘干率负相关不显著。３．后代中选率高。经多年应用，已有一批后代品种问世，在生产上发挥了重要作用
One is a high-starch sweet potato powder new varieties of sweet potato. Due to its outstanding high rate of drying (39.5%) and high rate of flour (29.3%), many breeders, beyond their use as a cultivar after their introduction, are being used as parent material. After nearly 10 years of application shows that cotton powder is indeed an excellent parenting material. Mainly in: 1. The general combining ability of three main characters (fresh weight of potato, dry weight of potato, drying rate) of offspring roots were high, and the variance of special combining ability was also large. 2. The average drying rate of descendants materials is high, the negative correlation between fresh potato and drying rate is not significant. 3. The success rate of future generations is high. After years of application, a number of offspring varieties have come out and have played an important role in production
