Additive genetic variance and covariance between relatives in wheat crosses with variable parental ploidy levels
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'Synthetic hexaploid wheat was developed and used in breeding to introduce new genetic diversity into bread wheat, through interspecific hybridization of T. tauschii (diploid) and durum wheat T. turgidum (tetraploid) to produce synthetic derivatives. Therefore, one may infer that the genetic variances of native wild populations vs. improved wheat may be different due differential origin and evolutionary history. We investigate this idea by partitioning the additive variance of grain yield with respect to breed origin using data from a synthetic derivative. Such information is needed to predict breeding values of synthetic derivatives and their parental populations. A mixed model with a heterogeneous covariance structure for breeding values was employed to estimate variance components using a program written by us. Data originated in a mu' .
