Diallel analysis assumes that the genetic interactions contributing to trait variation can be adequately captured by GCA and SCA effects. However, in reality, more complex, involving higher-order epistatic interactions, pleiotropy, other factors are not accounted for traditional diallel analysis, this purpose, studies were conducted study combinatorial ability of wheat varieties widely planted ...

The results on optimal diallel cross designs are based on standard linear model assumptions where the general combining ability effects are taken as fixed. In many practical situations, this assumption may not be tenable since often one studies only a sample of inbred lines from a possibly large hypothetical population. A random effects model is proposed in this paper that allows us to obtain a...

Monoterpene patterns of different larch species (Larix deci-dua, Larix kaempferi, Larix sibirica, Larix gmelinii). In: Results and future trends in larch breeding on the basis of provenance research. Abstract Procedures to analyze half-diallel mating designs using the SAS statistical package are presented. The procedure requires two runs of PROC VARCOMP and results in estimates of additive and ...
