In the present paper, an brief historical account and the comments on the modern taxonomic systems of the genus Triticum L. are made. The author suggests that principles to determine a species be (1) a special type of genome, and (2) reproductive isolation. The principles to determine a subspecies are the special co-type of genome and incomplete reproductive isolation. There are no differences on the level of genome constitution and no reproductive isolation between the varieties or concultivars. According to these principles, the author schemes a taxonomic system of the genus Triticum L. based on biosystematics as follows:
Triticum monococcum L. sensu lat.
subsp. boeoticum (Boiss.) Yen, st. nov.
var. thaoudar (Reut ) Flaksb.
concv. Einkhorn
subsp. urartu (Tum.)Vap.
T. timopheevi Zhuk. sensu lat.
var. araraticum (Jakubz.) Yen, st. nov.
T. zhukovskyi Men. et Er.
T. turgidum L. sensu lat.
var. dicoccoides (Körn. in litt. in Schweinf.) Bowden
concv. (1) Emmer, (2) Durum wheat, (3) Rivet wheat, (4) Polish wheat, (5)
Persian wheat.
T. aestivum L. sensu lat.

There are more than 20 species of Calligonum in China, of which 17 are known
from Xinjiang. They are divided into four sections. This paper aims to study the
evolutionary relations of some species of Calligonum in Xinjiang. The chromosome
numbers of 13 species and the anatomic structures of young branch of 8 species have
been examined.
Among 13 species, the, basic chromosome number x=9.9 species are diploids. 4
species are tetraploids.
The evolutionary relations of these plants are arranged as follows:
Section Calligonum (Fisch. et Mey.) Borszcz.
1. C. junceum (Fisch. et Mey.) Litv.
Section Pterococcus (Pall.) Borszcz.
2. C. leucocladum (Schrenk) Bge.
3. C. aphyllum (Pall.) Gürke.
4. C. rubicundum Bge.
Section Calligonum
