Partial 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...
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 کاملRobustness of Diallel Cross Designs Against the Loss of Any Number of Observations ( Crosses ) in a Block
The robustness of universal optimal binary balanced block (BBB) designs for diallel crosses has been investigated for the loss of any t (~1) observations (crosses) in a single block as per connectedness and A-efficiency criteria. It is observed that all the BBB designs for diallel crosses with the minimum eigenvalue strictly greater than 2 are robust as per connectedness criterion. Further A-ef...
متن کاملThe Theory and Analysis of Diallel Crosses.
T H E diallel cross method of investigating the genetical properties of a group of homozygous lines has recently received much attention. HULL (1945) has considered some aspects of the method. A short summary of a more general approach by JINKS and HAYMAN (1953) and its application to several published sets of maize data has also appeared. In another paper JINKS (1954) has described experiments...
متن کاملSpace-Time block codes from orthogonal designs
We introduce space–time block coding, a new paradigm for communication over Rayleigh fading channels using multiple transmit antennas. Data is encoded using a space–time block code and the encoded data is split into n streams which are simultaneously transmitted using n transmit antennas. The received signal at each receive antenna is a linear superposition of the n transmitted signals perturbe...
