Shahla and Tsuchiya (1984) have presented further evidence that ac2, albino seedling, is located on the short arm of chromotome 1 using 1L acrotrisomic analysis. These data add to data presented previously by these authors (Shahla and Tsuchiya, 1982 and 1983).

Telotrisomic analysis (Triplo 1L and Triplo 1S) of the gene f8, Chlorina 8 indicated that this gene is located on the short arm of chromosome 1 (Shahla and Tsuchiya, 1984b). Tsuchiya (1972) previously reported that f8 was associated with the long arm of chromosome 1.

A new recessive brachytic mutant (648AK) was induced by N-nitroso-N-methylurea in the variety Aramir (Szarejko and Maluszynski, 1984). Genetic analysis with translocation tester stocks located the gene on chromosome 1 and allelism tests indicated that the newly induced gene 1s allelic to br (Szarejko and Maluszynski, 1984).

Linde-Laursen (1984) reported the localizations by Giemsa C-banding of the breakpoints of 26 translocation stocks, 6 of which involve chromosome 1. This technique appears promising for precisely locating translocation breakpoints.
