-
摘要: ‘龙薯24号’是福建省龙岩市农科所于2005年以‘龙薯39-1’放任授粉选育成的甘薯新品种, 在福建省区试和生产试验中, 该品种晒干率31.97%, 比对照高6.51个百分点;出粉率21.45%, 比对照高5.66个百分点。平均薯干产量与对照‘金山57’相当, 淀粉产量显著高于对照。‘龙薯24号’薯干产量及淀粉产量高, 鲜食品质优, 较抗甘薯蔓割病, 是一个理想的淀粉型品种。2013年通过福建省品种审定委员会审定 (闽审薯2013002) 。Abstract: A new sweet potato cultivar Longshu24 was selected and bred from Longshu39-1by opening pollination in2005 by Longyan Institute of Agricultural Science, Fujian province.The results of Regional trial and production experiment of Fujian Province showed that the average yield of dry matter of Longshu24 was equivalent to the control (Jinshan57) , and the yield of starch was significantly better than that of the control.The dry matter content and yield of starch of tuberous root were 31.97%and 21.45%respectively.The results showed that Longshu24 is an ideal compatible cultivar with high dry matter content and high yield of starch, good edible quality, and relatively resistance to fusarium wilt.It had been approved by Fujian crop Variety Examination Committee in 2013.
