346 REPORT OF THE CONFERENCE ON GENETICS. 
Form B, very slightly modified in the direction of a soft wheat with 
white grain. 
B' was a soft wheat, with shorter spikelets and red grain (both its 
parents being white-grained). 
B? was a bearded soft wheat, resembling B, except in being bearded. 
B and B' reproduced true to themselves in 1887. B? produced seven 
bearded and three beardless out of ten plants. 
C was a beardless soft wheat, with very shiny glumes. It produced in 
1884, besides type C, a wheat C', bearded, with a compact ear, and with 
glumes of a dark grey, hairy and with the grain long, slender, red, and 
glazed: it was an intermediate form between soft and durum or 
turgidum, but nearer to durum. This form kept much the same until 
1894. 
In 1885, type C disappeared, in the sense that it produced two forms 
C* and C*, both of them distinct from type C. These were wheats with 
widened ears, very pointed glumes, and similar enough to each other. 
In 1886, type C? was abandoned as being less vigorous than C*. 
Type C* subdivided, in the same year, into two forms. The one which 
we kept as C3 was a durwm wheat, bright russet, bearded, but with very 
hollow straw, and shelling out easily. 
The other form, C‘, had solid straw, falling beard, the glumes of the 
ear hairy and pointed, and of a grey colour. (Both parents had white 
ears.) 
D was like a Pologne (polonicum), and was discarded in 1884. 
Then, between 1883 and 1887, this cross between Tr. polonicum 
(Pologne) and Tr. turgidwm (‘ Pétanielle blanche’) had produced a great 
number of variations, of. which seven were preserved and were still exist- 
ing in the above years. These are A, B, B', B’, C', C’, C4, which I am 
now going to describe. : 
Let us now examine what has happened with these different types. 
A Has neyer varied from the beginning. 
B.—This wheat, which we have noticed, was a soft one, beardless, 
with white grain; it has always produced soft wheats, reproducing its 
type more or less until 1890, when it was given up. But in 1889 
produced two interesting variations : 
B2 whose characteristics were a beardless spelt, with a very slender 
ear ; but these peculiarities were not reproduced, and in 1890 this 
form was destroyed. 
B3 was a wheat with a very compact ear, which has been pre- 
served to the present time, and has never given any varieties, 
but has gradually modified its form, being more or less compact 
from year to year, but on the average being much less so than 
at the beginning. 
B'.—Had not varied until 1890, the time at which it was destroyed.
