Enclosed is the estimation of covariance for a 7x7 diallel cross design that I found in a workshop manual. However, using the formula and example provided, I am not able to calculate w2, w3, w4,..., w7! only w1 is possible!
Dear Farhat!
Use excel for computing the covariances. If these formulae don't fit. Then read the methods given in "Biometrical methods in quantitative genetic analysis", by BD Singh and RK Chaudhary, 1979.
If you want to use software for calculating them, use this link to download Dial98. It will give you many things in diallel analysis.

thanks Dr Tahir. do you know any software for Six populations analysis
Dear Ehab El-Harty!
If you mean to have software for 6x6 diallel cross analysis, then you can use Dial98 for that as well.
Dr. Tahir. no I mean 6 populations, the parents(2), F1, F2, Back crosses (2)
No. That is actually designed for Diallel analysis. What parameters do u want to find out?
Last night after 3 days thinking, I finally found my mistake which was belonged to failure in considering previous members of diallel table,
Anyway, I'd like to appreciate you all for support and guidance...
Dr Tahir I have diallel but because I have more hybrid seeds of some crosses. I decided to make back crosses to their parents. right now I can not analysis these 6 populations.
Yes Sir. You can have a look at generations means analysis. That would most likely be what you would think of.
Yes sir. I would think to have a look at generation means analysis in such situation.
