摘　　要：从福建龙岩蛋鸭原种场选择7个蛋鸭品种(品系)S1、S2、S3、J、P、F、K,组建5组不同的三系杂交配套组合:J♂×(F♂×S1♀)、P♂×(F♂×S3♀)、F♂×(P♂×S2♀)、F♂×(K♂×S2♀)、F♂×(P♂×S3♀).5个配套系商品代经500日饲养试验测定,筛选出生产性能最优的2个配套系为青壳蛋系J♂×(F♂×S1♀)、白壳蛋系F♂×(P♂×S3♀).青壳蛋系的产蛋率达50%时,平均日龄(118±2.45)d,平均体重(1595.6±22.5)g,500日龄的产蛋数、总蛋重、蛋重、料蛋比分别为(330.6±4.29)枚、(22.69±0.21)kg、(72.50±0.20)g、(2.86±0.03)∶1;白壳蛋系的产蛋率达50%时,平均日龄(114.7±1.25)d,平均体重(1526.6±12.31)g,500日龄的产蛋数、总蛋重、蛋重、料蛋比分别为(335.29±1.8)枚、(23.22±0.17)kg、(71.36±0.05)g、(2.77±0.01)∶1.可见,2个配套系的生产性能均达国内领先水平,具有推广应用价值.Seven laying duck species or strains were selected from laying duck species population resources in Longyan, Fujian Province to develop muhiplicative strain with crossbreeding. 5 multiplicative strains of three line hybrid were established. They were A strain, J male x （ F male x S1 female） ; B strain, P male x （ F male x S3 female） ; C strain, F male x （ P male x S2 female） ; D strain, F malex （K male xS2 female） and E strain, F male x （P male xS3 female）. Data were recorded from one day old to 500 day old. The results showed that A strain （green-shell egg line） and E strain （white shell egg line） had better production per iormance than others. When laying rate of A strain （green shell egg line） came up to 50%, the average age was （118 ±2.45） d and average body weight was （ 1595.6±22.5） g. In the 500 days of age, （330.6 ±4.29） eggs were obtained, total weight of eggs was （22.69 20.21） kg, the weight of eggs was （72.50± 20.20） g and feed efficiency was （ 1：2.86± 20.03）. When laying rate of E strain （white shell egg line） came up to 50%, the average age was （114.7 ± 1.25） d and average body weight was （1526.6 ± 12.31 ） g. In the 500 days of age, （335.29 ± 1.8） eggs are obtained, total weight of eggs was （23.22 ± 0.17 ） kg, the weight of eggs was （71.36 ±0.05） g and feed efficiency is （ 1：2.77± 20.01 ）. Both A strain and E strain could be disseminated because of leading in the production performance of other laying duck species or strains.
