IX. 1. Correction of barley genetics literature
Shahla, A. and T. Tsuchiya. 1980. Trisomic analysis of the gene (f3)
for chlorina 3 in barley. J. Herod. 71:359-361.
At the end of the fifth line of the last paragraph of Discussion in
p. 360, it stated that "This indicated that the gene f3 belongs
to linkage group V." This line should be read, "---------- f3 belongs to
linkage group 5."
The authors' manuscript was written as follows: "--- f3 belongs to linkage group No. 5."
Editor(s) of Journal of Heredity changed it to "---linkage group V" without authors' knowledge. The junior author made correction in the gally proof and changed to "---linkage group 5." However, editor(s) apparently ignored the author's correction.
As all, or almost all, barley workers know now, the system of designating linkage groups by Roman numerals, I, II, III, ---VII in barley was terminated in 1961 when the new system was proposed by Kramer and Blander (1961) and Tsuchiya (1961), independently. The new system with the use of Arabic numerals, 1, 2, 3, ---7 was officially adopted by Robertson (1964), Nilan (1964), Robertson et al. (1965).
Therefore, designation of linkage groups by Roman numerals means the old system and linkage groups shown by Arabic numerals are the new system. This confusion occurred in the following article (cf. Tsuchiya, 1978):
Zali, A. A. and R. W. Allard. 1976. The effect of level of heterozygosity on the performance of hybrids between isogenic lines of barley. Genetics 84:705-775.
In order to make the situation clear, I will present the following table again:
I hope this will help some workers who are still not familiar with the new system.
