A barley beta-glucanase gene was located on chromosome I by southern blot analysis with digests from wheat-barley addition lines by Ahluwalia and Fincher (1988).

Eleven sodium azide-induced xenia expressing shrunken endosperm mutants (sex) were characterized by Harris et al. (1987). One recessive monofactorally inherited mutant (B9) was located to the short arm of chromosome I by means of detecting linkage with translocation breakpoint. Although allele tests were conducted among the eleven mutants selected with no allelism detected, allele tests were not conducted with already described and located sex mutants (Scheuring and Ramage, 1976; Ullrich and Eslick, 1978).
