5. Brittles and other genes.


Our stock of bt4 is the same as bt1; agreeing with the report in an earlier News Letter. Other brittles are being tested. I understand that bt3 has been lost (does anyone have it?)


The following characters appearing in the corn breeding project and in other material are established:


An excellent white‑striped character -- different from j, sr, f; brittle endosperm; upright tassel, expanded tassel glumes, su2 type endosperm, vivipary, glossy.


Identity and linkage tests are in progress.
