摘要
本文导出了在完全双列杂交试验下,胚乳性状的 F_1代、F_2代以及高世代的配合力模型和杂种优势模型。
Two genetic models for 3N complete diallel were presenLed in this paper.One is for the analysis of combining abilities:y_(iij)=m+2g_1+g_j+s_(iij)for generation 1 and y_(ij)=m+g_i+g_j+s_(ij)for generation n(n(?)2);the other is for the analysis of heterosis:y_(iij)=μ+2/3-v_1+1/3-v_j+y(h+2h_1+h_j+s_(iij))for generation 1 and y_(ij)j=μ+1/2-v_i+1/2-v_j+1/2~n-h+3/2~n(h_i+h_j)+1/2~n s_(iij)+s_(iij))for generation n.The esti- mation of genetic parameters and ANOVA corresponding to these two models in generation 1 were presented in detail.The relationship between the parameters of these two models was also discussed in detail.
