The partial circulant diallel cross at the interpopulation level

Abstract: The partial circulant diallel cross mating scheme of Kempthorne and Curnow (Biometrics 17: 229-250, 1961) was adapted for the evaluation of genotypes in crosses at the interpopulation level. Considering a random sample of n lines from base population I, and that each line is crossed with s lines from opposite population II, there will be ns sampled crosses that are evaluated experimentally. The means of the ns sampled crosses and the remaining n(n -s) crosses can be predicted by the reduced model Y ij = m + g… Show more

“…genotypes, but its limitation is the increasing number of crosses in accordance with the increase in number of lines (Gonçalves, 1987;Hallauer & Miranda Filho, 1988;Kempthorne & Curnow, 1961;Martins & Miranda Filho, 1997;Miranda Filho & Vencovsky, 1999). Sprague & Tatum (1942) found that general combining ability (GCA) was relatively more important than specific combining ability (SCA) for unselected inbred lines, but the opposite was observed for selected lines.…”

“…Análise dialélica foi realizada utilizando-se do software SAS, com a média das repetições, seguindo o modelo proposto por Miranda Filho & Vencovsky (1999). , sendo Y o vetor de média observadas (ns híbridos) ; X a matriz dos coeficientes com valores de 0 e 1 relacionados aos parâmetros m, g i , g j e s ij ; β d vetor dos parâmetros a serem estimados e ε é o vetor representativo do erro associado às médias.…”
