摘　　要：本研究以国家水禽品种资源基因库(福建)内保护的金定鸭、莆田黑鸭、连城白鸭、绍兴鸭、攸县麻鸭、山麻鸭等6个鸭品种为对象,通过比较6个品种不同世代的生长性能和蛋品质指标,分析"家系等量随机选配法"在水禽基因库保种中的应用效果,为进一步丰富和完善水禽保种技术及理论提供依据。结果表明,6个品种不同世代间不同日龄体重、300日龄体尺、产蛋性能及蛋品质测定结果均无显著性差异(P>0.05),且测定结果均符合国家标准及畜禽遗传资源志对该品种的描述。在闭锁小群体中采用"家系等量随机选配法"能有效地保存水禽品种资源的遗传多样性。In this study ,the growth performance and egg quality of different generations of six duck populations from National Waterfowl Species Gene Bank （Fujian） were compared and analyzed . The results indicated that weight of different age , 300-day-old body size ,laying performance and egg quality had no significant difference among different generations of the six duck populations （P 〉 0.05） , and all the results met the national standard and the descriptions of Animal Genetic Resources . The conclusion showed that genetic diversity of waterfowl germplasm resources coubl effectively be preserved by the “family equimultiple random select cross method” in small closed population ,which benefitted for enrichment and improvement of the theory and technology of waterfowl conservation .
