2Introduction
- International Winter Wheat Improvement Program
(IWWIP) is a joint venture between the Ministry
of Agriculture and Rural Affairs of Turkey,
CIMMYT and ICARDA. The objective of IWWIP is
improvement of winter/facultative wheat on a
global scale through international breeding
program in Turkey, facilitation of international
germplasm exchange and networking. In the early
1980s Turkey and CIMMYT established joint winter
wheat breeding program for the region based in
Anatolian Plateau of Turkey. In the late 1980s
ICARDA Highland Wheat Breeding Program joined
IWWIP to establish a well integrated
international breeding framework. The main
mandate area of IWWIP is presented on Fig. 1. In
total, there are close to 15 mln ha of winter
wheat in the region. The bread consumption in the
region is very high (40-55 of daily calories
come from wheat) making wheat very important
crop. There is also substantial area of winter
wheat in Russia, Ukraine and Eastern Europe. The
breeding programs in these countries also
cooperate closely with IWWIP.

4IWWIP breeding framework in Turkey
IWWIP utilizes tremendous diversity of Turkey in
its breeding framework (Figure 2). The wheat
cultivation environments vary in Turkey from
typical coastal high rainfall spring wheat to
cold and dry winter wheat grown at the altitudes
of 1000 masl and higher. The crosses are made in
Izmir (Turkey) and Aleppo (Syria) which are
mostly spring wheat environments. The resulting
F1s are grown in the same locations. F2
populations are screened for cold tolerance and
agronomic type at Anatolian Plateau (800-1000
masl) in Eskisehir. Selected F3 populations are
subjected to screening under artificial
inoculation by Yellow Rust in Ankara. Consecutive
selection is again done in Eskisehir including
the headrows. The Preliminary Yield Trials are
planted at 2-3 locations. The Yield Trials and
Advanced Yield Trials are planted at 5-6
locations covering the typical environments as
well as the hot spots for diseases. There are two
streams of germplasm targeting irrigated and
rainfed environments. The best selected lines are
distributed through the international nurseries
system. The overall volume of breeding work is
presented in Figure 3.

15IWWIP breeding objectives and results
- IWWIP breeding objectives reflect the
environmental challenges, biotic stresses,
technologies applied by the farming community and
the end-use preferences . The following traits
are considered important - Broad adaptation and stable yield across changing
environment - Drought tolerance for the germplasm targeted for
semi-arid environments - Grain quality
- Resistance to diseases and primarily rusts
- Yellow Rust
- Leaf Rust
- Stem Rust
- Cold tolerance and winter hardiness
- The progress reached in breeding for yellow and
leaf rust is reflected in Figure 4. It is obvious
that the majority of the germplasm demonstrate
resistance to yellow and leaf rusts.

17- The new stem rust race Ug 99 appeared in Africa
(Uganda, Kenya, Ethiopia) and devastated wheat
production in those countries. This is a great
concern that it will spread to North Africa,
Middle East, Turkey, Iran, Central Asia and
Indian subcontinent. The majority of the
currently grown varieties (both spring and winter
types) are susceptible to this new race. On
average 10-15 of the Global Rust Initiative
(GRI) started by CIMMYT and ICARDA to prevent
losses from stem rust. Wheat germplasm is
screened in Kenya and Ethiopia. The 2006
screening resulted in identification of resistant
germplasm (Table 1) which will be utilized in the
crossing program. - The overall good progress in yield, adaptation
and other traits has been achieved so far (Table
2). Improvement of grain quality remains
important priority both for Turkey and for
Central Asia and Caucasus region.

20International cooperation network
- IWWIP maintains strong cooperation with key
winter wheat programs outside of Turkey which
assist in the germplasm evaluation and
distribution (Figure 5). IWWIP also remains the
only international program actively facilitating
global winter wheat germplasm exchange. Many
breeding programs routinely send the germplasm to
Turkey for multiplication and global distribution
through international nurseries (being used in
breeding activities). The data obtained from
cooperators is summarized and made available to
the breeding community. From 2007 IWWIP offers
the following nurseries to winter wheat breeding
programs - Facultative and Winter Wheat Observation Nursery
for Irrigated Conditions (FAWWON-IRR) small
plots for evaluation and selection - Facultative and Winter Wheat Observation Nursery
for Semiarid Conditions (FAWWON-SA) small plots
for evaluation and selection - Facultative and Winter Wheat Yield Trial for
Irrigated Conditions (FAWWYT-IRR) replicated
trial for yield evaluation - Facultative and Winter Wheat Yield Trial for
Semiarid Conditions (FAWWYT-SA) replicated trial
for yield evaluation - All the nurseries include the germplasm
developed by IWWIP and submitted by cooperating
programs from outside of Turkey. - Selections from international nurseries resulted
in a number of new wheat varieties released in
Turkey, Iran and Central Asia/Caucasus region
(Table 3).

centers and programs in Turkey and it is only
possible due to contribution of the partners and
the cooperators worldwide.
