Tajikistan is a small mountainous country in the southern part of Central Asia. It has a<br />

long history of agricultural civilization and is counted as one of the centers of origin and<br />

diversity of cereals, including wheat, as confirmed by the expeditions of Academician<br />

N.I.Vavilov early in the 20th century. As in other Central Asian countries, bread is the<br />

staple food of the Tajik population but historical circumstances and changes in the social<br />

and political lifestyle patterns have had a profound impact on agriculture generally, and<br />

on wheat production.<br />

Within the Soviet Union, Tajikistan was designated primarily as a cotton producer particularly<br />

in the more productive irrigated areas of the country. Cereal crops were of less<br />

importance because supplies could be easily imported in bulk from Russia and Kazakhstan.<br />

After gaining independence in 1991, Government policies had to adapt rapidly to<br />

changing economic circumstances and food security became a high priority.<br />

Tajikistan is still predominantly an agrarian country with 52% of the workforce engaged<br />

in agriculture. However, 93% of the territory is occupied by mountains and the total area<br />

of agricultural land is only 1.57 mln ha, of which about 850, 000 hectares are suitable for<br />

arable crops, equivalent to 0.11ha per capita. Given such limited land resources, there is<br />

a heavy responsibility on government and the people to use of every hectare of land as<br />

effectively as possible. Total area of wheat is about 350, 000 hectares, of which 140, 000<br />

hectares are irrigated.<br />

Wheat breeding research in Tajikistan began in 1926 under the direction of I.G.Sukhobrus.<br />

In the 1940s and 50s, several successful wheat varieties were developed including Surkhak<br />

5688, Surkhak Yubileynaya, Iroda 1006, Khoranka 46, Tajikskaya Chernokolosaya,<br />

Tajikskaya 16 which became widely grown in the country. Between 1959 to 1963 the<br />

bread wheat Surkhak 262 and durum wheat Shark, were released, while in the 1980 and<br />

90’s breeding became focused on dwarf varieties suitable for intensive production. After<br />

independence, new linkages opened up with the International Centers such as CIMMYT<br />

and ICARDA and the collaborative International Winter Wheat Improvement Program<br />

(IWWIP), between CIMMYT, ICARDA and Turkey. Despite the historical success of<br />

Tajik wheat breeders, the maintenance of an independent breeding programme for such<br />

a small national acreage could not be justified. Therefore since 1999 the breeding strategy<br />

for wheat was to strengthen cooperation with the international research centers and to<br />

select new varieties from among their large collections of germplasm. The main breeding<br />

objectives were high grain yield, resistance to rusts, especially to yellow rust, and drought<br />

tolerance. Later on selection for grain quality was included in the breeding objectives.<br />
