摘　　要：通过对豫州蛋鸡５个品系间不同杂交组合的配合力测定表明：褐壳蛋鸡Ⅰ×Ⅱ组合性能最佳。其开产日龄为１６７ｄ；０～６周龄成活率为９７．３５％；２１～７２周龄成活率为８９．２８％；７２周龄产蛋２３．２５枚，总重量为１６．０３ｋｇ；料蛋比２．５５：１。上述各性状的杂种优势率分别为—２．９１％，６．８６％，１．１５％，３．２０％，—１０．３７％，且该组合蛋品质优良，雏鸡能自别雌雄。The combining ability of the five strains of Yuzhou laying hens was determined. The results shows that the best combination was Ⅰ × Ⅲ strains. The age at first laying,the 0～6 weeks survival rate ,the 21～72 weeks survival rate, the 72 weeks laying quanti-ty ,the egg size,the feed conversion efficiency of the filial generation of this combination were 167d,97. 35%, 89. 28%, 263.25 eggs,16.03 kg and 2.55 :1 ,respectively. In this combination,the heterosis rate of the above mentioned was 2. 91%, 86%,15%,3.20%,6.23% and 10.37%,respectively. This combination also had better egg quality and was autosexing.
