摘要 [目的]研究吉林芦花鸡与吉林黑鸡杂交F1代生长发育规律，筛选出更优的杂交组合方式。[方法]试验采用吉林芦花鸡（LL）、吉林矮脚芦花鸡（AA）与吉林黑鸡（HH）采用完全双列杂交法构建6个杂交组合，外加3个亲本，共计9个组合，对各杂交组公母0～21周龄体重进行测定，最后运用3种非线性生长模型（Logistic、Gompertz、Bertalanffy）进行拟合分析。[结果]3个亲本及不同杂交组合F1代生长发育规律相似，均表现为周增重随着周龄的增加而增加的趋势，在9周龄周增重最高，此后呈现逐渐降低的趋势。3种生长模型中Bertalanffy模型与Gompertz模型在LL、LA、AL、HL、LH、AH各F1代组合中拟合度 R2 相同，AA、HA组合母鸡中Bertalanffy拟合度 R2 更高，HH组Gompertz模型公鸡拟合度高于Bertalanffy模型，Bertalanffy模型母鸡拟合度高于Gompertz模型。[结论]通过对F1代的生长发育拟合分析，筛选杂种优势高的配套系，揭示F1代的生长发育规律，为吉林芦花鸡与吉林黑鸡的杂交选育和开发利用提供了理论依据。

Abstract [Objective]To study the growth and development laws of hybrid F1 generation of Jilin Luhua Chicken （LL for short） and Jilin Black Chicken （HH for short）， screen out the optimal cross combination pattern. [Method]In this experiment， 6 cross combinations were established by complete doublerow hybridization between LL， Jilin Dwarf Luhua chicken （AA for short） and HH. Adding 3 crossing parents， total of 9 combinations were selected to measure the weight gain per week from 0 to 21 week age. Finally， the fitting growth curves were drawn by three nonlinear growth models （Logistic，Gompertz， Bertalanffy）. [Result]All 9 populations had similar growth and development laws. The weekly weight gain increased with the week age， and the weekly weight gain reached the maximum value at 9 week age， and then showed the gradually decreasing trend. Bertalanffy model and the Gompertz model had the same fitting  R2  in LL， LA， AL， HL， LH and AH F1 populations. Bertalanffy fitting  R2  was higher in hens than cocks in AA and HA populations. The cocks of HH population had better Gompertz fitting  R2  than Bertalanffy model. The hens of HH population had better Bertalanffy fitting  R2  than Gompertz model. [Conclusion]Through the fitting analysis of the growth and development of the F1 generation， the matching lines with high heterosis were screened out， and the growth and development laws of the F1 generation were revealed， which provided the theoretical basis for the hybrid selection and development of Jilin Luhua chicken and Jilin black chicken.

吉林芦花鸡、吉林黑鸡是吉林省重要的家禽遗传资源，是吉林省较原始的肉蛋兼用型地方鸡种，吉林矮脚芦花鸡由吉林省农业科学院选育，它们都具有耐粗饲、肉质好、抗寒和抗病力强等优点[1-2]。……
