Optimal Diallel Cross Designs for the Interval Estimation of Heredity
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...
متن کاملEstimation of ratio of variance components and optimal diallel cross designs
The results on optimal designs for diallel crosses are based on standard linear model assumptions where the general combining ability effects are taken as fixed. Recently Ghosh and Das (2003) proposed a random effects model that allows one to first estimate the variance components and then obtain the variances of these estimates. In this paper we first propose an unbiased estimate of the ratio ...
متن کاملOptimal Designs for Best Linear Unbiased Prediction in Diallel Crosses
Most of the available results on optimal block designs for diallel crosses 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. Recently Ghosh and Das (2003) proposed a ra...
متن کاملUse of Nested Designs in Diallel Cross Experiments
The term diallel is a Greek word and implies all possible crosses among a collection of male and female animals. Hayman (1954a, 1954b) defined diallel cross as the set of all possible crosses between several genotypes, which may be individuals, clones, homozygous lines, etc. Diallel cross is most balanced and systematic experiment to examine continuous variation. The genetic information related...
متن کاملPartial Diallel Crosses
A diallel cross is a set of all possible matings between several genotypes, which may be individuals, clones, homozygous lines, etc. Such crosses are used to estimate general and specific combining abilities of lines and crosses respectively. For ‘n’ inbreed lines, the possible F1’s are n(n–1)/2, which are to be tested in a suitably replicated randomized design. With facilities available for te...
