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.
