PARTIAL DIALLEL CROSS ANALYSIS FOR QUANTITATIVE TRAITS OF THREE CHICKEN BREEDS

Abstract

An experiment was carried out to estimate the genetic potency of three chicken breeds, those were Arab (A), Lingnan (L) and Kedu (K), based on the general and specific combining abilities. Griffing’s method II of diallel cross was used in this experiment. Parameters oberved were fertility, hatchability and hatching weight. The results showed that crossing affected significantly (P<0.05) the fertility, hatchability and hatching weight. Male DOC had higher body weight than female but there was no significantly different (P>0.05). Lingnan chicken was the highest in general combining ability of egg fertility (-4.28), while Arab chicken was the highest in hatchability (-1.86) and hatching weight (-2,12). Crossing of male K x female L was the highest in specific combining ability of fertility (15.03) and hatchability (15.70). Crossing of male A x female L had the highest value of specific combining ability of hatching weight. In conclusion, Lingnan female was the superior in fertility, hatchability and hatching weight compared to Arab and Kedu chicken. Keywords: Partial Diallel Cross, Quantitative Traits, Chicken
