II.39 Allelic relationships of genes for short-awned mutants in barley.

T. Tsuchiya, Department of Agronomy, Colorado State University, Fort Collins, Colorado 80521, USA.

There are two different systems of nomenclature and gene symbolization in barley; the one is more or less historic system and has been used for decades by most of barley geneticists, and the other is recent development mainly used by some European workers. This situation has caused confusion and inconvenience to some barley workers and has been a problem in genetic and linkage studies in barley.

It has been shown that genes of some recently induced mutants are allelic to those for the standard or established genetic marker stocks (Stubbe, 1959; Tsuchiya, 1973; Tsuchiya and Haus, 1973). This note briefly reports the results of an experiment on allelism testing between short-awned genes for established genetic stocks and newly induced mutants and between some different induced mutant strains. The materials used in this study are shown in Table 1.

Table 1. Short-awned Mutants used in this Experiment.

A total of 26 combinations were studied in F1 hybrids with the results summarized in Table 2.

Table 2. Summary of the F1 analysis between short awned and brachytic mutants.

The results shown in Table 2 suggest that there is no need to create a new name (Dearistatum) or a new symbol (ari- ) for mutants which are readily classified as short awn (lk) or brachytic (br) in the standard system.

The suggested name and symbol for the ari- mutants are as follows
