Kaiser and Friedt (1987) reported that two primary trisomic series, Shin Ebisu 16 (SE16) and Hordeum spontaneum var. transcaspicum (HST) are different in their characteristics in corresponding types. Since I was the one who produced both sets, it seems to be appropriate to make a comment on their report.
First, these authors apparently do not know I produced 'and reported the detailed characteristics of the primary trisomics in H. spontaneum var. transcaspicum (Tsuchiya, 1954, 1956, 1958, 1959, 1960). During the period of several years, I not only produced the complete set of primary trisomics in H. spontaneum, but also observed them the entire growing period from germination to maturity at least once a day. I measured and observed every detail of character expression during the growing period. I repeated this process at least several years. Detailed characteristics were described and photographs of many plant parts were published (Tsuchiya, 1958, 1960, 1964).
Similarly, I produced another complete set of primary trisomics in a two rowed cultivar, Shin Ebisu 16 (SE 16). Observations, measurements and details were published with photographs (Tsuchiya, 1967).
In my work, I conduct research work myself with or without assistance of colleagues. Therefore, I am quite familiar with almost every detail of the characteristics.
Furthermore, I have studied (Tsuchiya, 1969) three more complete series developed by E. R. Kerber (Gateway and others), R. T. Ramage and associates (Betzes), and E. N. Larter (OAC 21 4x × Montclam 2x).
Detailed studies of all five complete series showed almost the same qualitative characteristics with no exceptions.
When E. N. Larter sent a series of more than 20 sets of seeds, I was able to classify all seven primary trisomic types by observing seed characteristics which were exactly the same as those in Hordeum spontaneum and SE 16 mentioned above.
I have already published photographs of spikes of seven trisomic types in SE 16. 1 did not see any reason to print the pictures provided by Kaiser and Friedt. It should be pointed out that the picture of the spike for Triplo 1 is from the hybrid plant between SE 16 and a 6-rowed type. Apparently the authors did not recognize that.
