Variance-balanced row-column designs involving diallel crosses incorporating specific combining abilities for comparing test lines with a control line

摘要

In this paper, the problem of comparing t test lines with a control line under a row-column setup in complete diallel cross experiment is investigated when specific combining ability (sca) effect is included in the model. Three classes of Mating-Environmental Row-Column (MERC) designs have been obtained which are variance balanced for estimating the contrasts pertaining to general combining ability (gca) effects free from sca effects.
