Character identification and high yielding mechanism of sweet potato variety Quanshu 11

摘要: 泉薯11是泉州市农科所1996年以金山1255为母本、泉薯218为父本杂交选育而成,表现高产、稳产、适应性广、食味品质较好、中高干物率和抗蔓割病等特性.研究表明,叶面积较大和净同化率较高是泉薯11最显著的生理特性,且其生物产量较高、经济系数较大,表明泉薯11具有较高的丰产潜力,同时表明甘薯除"叶面积型"与"净同化率型"外,还可能存在中间型品种.Abstract: Quanshull was developed from the hybrization of Jinshan 1255/Quanshu218 by Quanzhou Institute of Agricultural Sciences in 1996. The variety performed high yield, stability, middle dry-matter content, resistance to stem rot and good storability. The study showed that high leaf area, high net assimilation rate were the most obvious characters, high biomass and high economic coefficient(0.85)indicated its potentiality of high yield. The results also showed that there might be a "Middle" type, beside "High Leaf Area" and "High Net Assimilation Rate" types in sweet potato.
