Chapter 1 Preface

As part of our effort to characterize the 'hybrid decay' phenotype described in Xue et al. 2019, we have collected phenotypic data for several sick hybrid lineages. All lineages descend from a Bravo Teosinte x W22 Maize hybrid backcrossed 7 times to W22 we received from John Doebley. We denote this hybrid as sW22 (may also be refered to as a Bravo BC7), and it is the earliest "sickly" phenotype we have.

We start by first detailing the data we have before going highlighting the results for each phenotypic trait.
