- 摘要:
- “曙光5号”是从河北沧州“金丝小枣”资源中选育出的抗裂果枣新品种。其果实圆柱形，平均单果质量12.64 g，最大果质量16.80 g，果实可食率为95.08%，可溶性固形物含量为34.50%，制干率为56.20%，干鲜兼用。在沧州地区10月中旬成熟，为晚熟品种。经2011—2015年连续5年调查，“曙光5号”的裂果率极显著低于“金丝小枣”（CK），平均比CK降低18.96个百分点。其早果性强，连续结果力强，丰产性好，经区域试验表明，“曙光5号”比CK平均增产11.66%。2015年12月通过河北省林木品种审定委员会新品种审定。
- Abstract:
- ‘Shuguang 5’ is a new Chinese Jujuba(Ziziphus jujuba Mill.) with high resistance to fruit cracking，which was selected from ‘Jinsixiaozao’ in Cangzhou,Hebei.The fruits are cylindrical.The average fruit weight is 12.64 g.The largest single fruit weight is 16.80 g.The edible rate is 95.08%.The soluble solids content is 34.50%.The desiccation rate is 56.20%.It is suitable for fresh-eating and dehydration.It is a late-maturing cultivar，the fruits ripe in the mid of October.‘Shuguang5’ has early bearing and productive abilities.After investigations from 2011 to 2015 it was showed that fruit cracking rate of ‘Shuguang 5’ was significantly lower than that of control(‘Jinsixiaozao’),which was decreased by 18.96 percent point compared with control.The yield of ‘Shuguang 5’ was increased by 11.66% compared with control in the variety regional test.It was approved by the Forest Variety Approval Committee of Hebei Province in December 2015.
