Diallel Analysis using the Griffing and Hayman approach is so common in plant breeding and genetics. I'm wondering if someone can share R worked example on Diallel Analysis. Is there any good referenced book which covered worked examples? Thanks

a link to a reference paper on "Griffing and Hayman diallel analysis" would be very helpful for non geneticists – RockScience Apr 4 '11 at 4:32
please how can i use SAS for diallel analysis involving three (3) parents. – user35611 Dec 3 '13 at 9:22

There is beta package plantbreeding, which can do diallel analysis.

They has a blog:

The following is example from this package:

 out <-diallele1(dataframe = fulldial, male = "MALE", female = "FEMALE",  
 progeny = "TRT", replication = "REP", yvar = "YIELD" )

out$anvout # analysis of variance 
    out$anova.mod1 # analysis of variance for GCA and SCA effects 
out$components.model1 # model1 GCA, SCA and reciprocal components 
    out$gca.effmat # GCA effects
out$sca.effmat # SCA effect matrix 
    out$reciprocal.effmat # reciprocal effect matrix 

out$varcompare  # SE for comparisions 
    out$anovadf.mod2   # ANOVA for model 2
out$varcomp.model2  # variance components for model 2

Thanks a lot @John. – MYaseen208 Mar 16 '13 at 4:21

I think it's unlikely that you'll find worked examples in R for the analysis of diallels.

I did find some references for diallel analysis in SAS (e.g., here, and there's a chapter on DIALLEL-SAS in the book Handbook of formulas and software for plant geneticists and breeders).

There's a nice worked example in the book Statistical and Biometrical Techniques in Plant Breeding by Jawahar R. Sharma on about page 184. Visible in Google books.
