HYBRIDS AND VARIATIONS IN WHEAT. BoD 
Bot. France,” tome xxx., Plate I.). It would be possible to multiply 
examples, but the same facts happen sufficiently often to make it un- 
necessary to quote them all. 
The family of which I am now going to speak, however, is too 
interesting to be passed by. 
4. ‘CHIDDAM D’AUTOMNE A EPI BLANC’ X ‘ BuE IsmMA#t.’ 
(Tr. satiwwum x Tr. durum.) 
This cross between a durwm and a soft wheat was effected in 1878. 
The two grains fertilised produced, in 1879, two plants of a soft white 
wheat, with square ears. 
The grains of these two plants (1 and 2) were sown separately, and 
gave very different results. In 1880, No. 1 gave 11 varieties, and No. 2 
8 varieties. 
The forms produced by No. 1, which we shall call 11,* 12, 18, 14, 15, 
16, 17, 18, 19, 197, 19%, and those by No. 2, which are 21,:22, 23, 24, 25, 
26, 27, 28, were, since 1881, remarkable for their relative fixity ; only the 
most interesting types were preserved and we had, in 1882: 
15—A soft wheat, red, with compact ear, very regular. Destroyed in 
1883. 
16—This wheat, which was a turgidwm, produced, in 1881, out of 
eight plants, six with glabrous ears (161) and two with hairy ears (162). 
161 was a white twrgiduwm, glabrous and bearded, with red grain. 
It has never varied, and still exists in 1906. | 
162 was a white twrgidum, hairy, bearded, with short white grain 
(fig. 96). It produced, in 1895, two beardless soft wheats, 
which were not preserved, and, in 1882, two forms: 
_ 1621 was like the type 162, and the origin of variations which 
we shall mention later on. 
1622, with longer straw, and longer in the ear, gradually 
returned to type 162, and was destroyed in 1901. 
19? was a russet, beardless, soft wheat, very slender, and difficult to 
husk; it produced, in 1882 and 1883, some bearded plants, and was 
destroyed in 1883. 
21 was, to begin with, a soft wheat, with large white beardless 
ears, With very short and stiff straw; in 1882, it varied a great deal, 
particularly as to the length of the straw; three forms were kept : 
211. Very like the type, with short and stiff straw. Destroyed in 
1883. 
212 was a soft wheat, with large white ear, beardless, rather 
hairy and white grain. In 1885 it produced two forms: 
2121 was a soft wheat, with glabrous ear and long white 
grain; in the course of time it became hairy, and still exists 
in 1906. 
2122. This wheat, selected in 1885, was true to type, became 
glabrous in 1886 and was destroyed.
