摘要
莆紫薯3号是以日清1号和台引2号为亲本,经杂交选育而成的紫肉甘薯新品种,2005年通过国家甘薯新品种鉴定(鉴定编号:国品鉴甘薯2015016)。对莆紫薯3号的形态特征、品质、抗病性、生产力和产量形成的生理特点等进行了研究,结果表明:莆紫薯3号地上部长势平稳,茎叶不易早衰,生育期应保持在150 d以上;鲜薯和薯干产量分别比对照宁紫薯1号增产7.51%和14.35%;薯块干率27.73%,比对照高1.88%;食味评分75.4分(对照为70分),优于对照;薯块粗蛋白和可溶性糖高于对照,还原糖低于对照;中抗蔓割病,中感薯瘟Ⅰ型,感薯瘟Ⅱ型。
        A new purple sweet potato variety Puzishu 3 was bred from the hybrid offspring of Riqing 1 and Taiyin 2,with high stable yield and good eating quality. It was approved as a new national sweet potato variety in 2015. The morphological characteristics, quality characteristics, disease resistance, productivity and physiological characteristics of yield formation of the variety were studied. The results indicated that Puzishu 3 had a growth period more than 150 days. Based on regional tests in Fujian Province, the fresh root yield, dry matter yield and dry matter content increased by 7.51%, 14.35% over the control variety Ningzishu 1. The taste score of Puzishu 3 was 75.4(70 for CK). Root quality appraisal showed that the contents of crude protein and soluble sugars in the root of Puzishu 3 were higher than that of CK, while reducing sugars was lower than that of CK. Puzishu 3 showed moderate resistance to sweet potato Fusarium wilt, middle susceptible to sweet potato Pseudomonas solanacearum Ⅰ and susceptible to sweet potato Pseudomonas solanacearum Ⅱ.
