Cytogenetics of a Temperature-Sensitive Albino Mutant in Smooth Bromegrass (Bromus inermis Leyss)¹

Tetrasomic inheritance was demonstrated for a temperature-sensitiire albino mutation in smooth bromegrass, Bromus inermis Leyss. Evidence was obtained for both chromatid and chromosome segregation. The original mutant plant had 55 chromosomes, whereas the norma1 green parents had 56 chromosomes. Pairing was largely as bivalents, and the number of meiotic irregularities in this material did not exceed the number normally found in the species. The chlorophyll deficiency was probably due to a gene mutation rather than to gross chromosomal aberration. This study supports the two genomic model proposed for B. inermis, but does not exclude the three genomic model.

Key Words: Tetrasomic • Double reduction • Genome
