Two-point linkage data for gl1 Bn1 on chromosome 7
--Philip Stinard

This report summarizes the results of a two-point linkage study of gl1 and Bn1 on the long arm of chromosome 7. The test was set up as a repulsion backcross as follows: (y1 gl1 bn1 / y1 Gl1 Bn1) X y1 gl1 bn1 (the test was done in a y1 background in order to facilitate scoring of Bn1). The kernels from this cross were separated on the basis of Bn1 vs. bn1 phenotype and separately planted and grown to seedling stage in sand benches. The seedlings were scored for gl1. The results of this test are presented here. The gl1 - Bn1 distance of 27.8 centimorgans is reasonably consistent with the distance presented on the current linkage map (35 centimorgans).
