The partition of the hereditary variance was outlined by Fisher (l9l8) on the basis of the genetic covariation and correlation between relatives. Comstock and Robinson (1948; 1952) provided mating designs for the estimation of the variance components on an experimental basis. Cockerham (1954) and Kempthome (1954) extended Fisher's theory by providing general formulations that fucluded an unlimited number of alleles per locus, arbitrary fubreeding, and epistasis. Hallauer and Miranda Filho (1995) presented the details of the genetic statistical procedures for the estimation of the components of genetic variance in maize populations. The mating scheme, known as chain crosses, was suggested by Lonnquist (1961) as a variation of recurrent selection based on full-sib progenies. However, the components of genetic variance expressed amongst progenies from chain crosses have not been studied. This study provides the statistical models and procedures for futerpreting the analysis of variance for the estimation of the components of the genetic variance from chain crosses in random mating populations.
