354 REPORT OF THE CONFERENCE ON GENETICS. 
213 was a soft wheat with long straw, with a very flat red ear, 
easily husked and with long red grain. Reproduced itself in 1883, 
with the exception of one white plant, and was destroyed. 
22. From wheat 22, of 1880, of which no description was kept, arose 
three forms in 1881 : 
221. A durum, white, square, awned, rather hairy. It remained 
true to type for ten years, and was killed by frost in 1891. 
222. A durum, red, glaucous, bearded, compact, easily husked, and 
in fact approaching to a twrgidwm, kept to type, and still exists 
in 1906. 
223 was a soft wheat, white, beardless, pyramidal, and with 
white grain; produced, in 1882, some feeble and uninteresting 
variations, and was destroyed in 1883. 
23 was a durwm wheat, glaucous, white and beardless. In 1882, it 
produced a bearded plant, which was not preserved ; after that it remained 
fixed until 1898, and then produced : 
231 remained fixed, and later on, in 1904, was destroyed as too 
nearly approaching the following variety : 
232. On the lower half of whose ear all the spikelets were abortive ; 
otherwise the ear has always been a glaucous, white, beardless 
durum. This curious characteristic has remained fixed, and 
the wheat still exists in 1906. 
26 was a beardless, red, soft wheat, with a very compact ear; it re- 
produced itself for two years, and was destroyed in 1883. 
As it will appear, these types varied very little, and, in 1902, the only 
ones still in existence were 161, 1621, 2121, 222, 232; the others 
were either killed by frost or destroyed as not being of sufficient interest. 
But out of these five wheats still existing in 1902, four have not pro- 
duced, to the present time, a single variation; whereas No. 1621, which 
remained fixed for twenty-two years (with the exception of two beardless 
soft wheats, which appeared in 1895, and were not preserved), only 
produced one slight variation in 1898, that alone preduced a large number 
of variations, which we shall now proceed to study. 
1621, in 1902 (see above), was a hairy, white, and bearded turgidwm. 
In 1903, it produced three forms: 16211, 16212, 16213. 
16211 kept to type, and was cnly represented by two dwarf 
plants: it varied again in 1904, and produced two forms, 162111 
and 162112. 
162111 remained to type, and did not vary in 1905. 
162112 was a soft beardless white (fig. 96). In 1905, it did 
not produce a single plant like the selection of 1904. Out 
of four plants, there were four forms, out of which one 
resembling 162111 was destroyed. The others were: 
1621121. A bearded, white, soft wheat, with long and 
elabrous ear (fig. 96). 
1621122. A soft wheat, white, bearded and _ hairy 
(fig. 96). 
1621123. A soft wheat, white, beardless and hairy, but 
with a very compact ear (fig. 96).
