Kempthorne , O. ,
Curnow , R. N. ( 1961 ). The partial diallel cross . Biometrics 17 : 229 – 250 .Crossref], Web of Science ®] , Google Scholar]) proposed the estimation of the yielding capacity of any cross based on the least square estimators of the general combining ability effects and/or the mean yield of the cross (i, j). In this article, the problem of predicting the yielding capacity of the cross (i, j) from the sample of inbred lines has been considered. The properties of the best linear unbiased predictor for predicting the unobserved general combining ability effects together with general mean effect has been studied. We characterize A-optimal complete diallel cross designs and some efficient partial diallel cross designs under this setup. |
