to dwarfs, cover about 20 percent of the wheat
areas of central and southern Iran.
The Government has set a base price for
wheat at 6,000 reals/ton. Although some of it
is purchased at this price, there is insufficient
government intervention in the market to stabilize
prices. In some areas, organized marketing
is in its infancy and prices fall at harvest.
Thus in good years prices fall -in poor ones
they rise.
Under a recent reorganization of research
stations, six have been designated main centers
and 16 sub-centers. Crossing is effected
at all main centers, but most is now done at
Karaj, the National Center near Teheran.
Trials are conducted under the designations
of station trials and A, Band C type series.
The station trial is nonreplicated with a common
check in every fifth plot. The A trials
consists of six replicates in a randomized block
and are grown in a region. Superior lines enter
the B triars, again of six replicates, but in
a triple lattice, and form a more advanced
zonal trial. Finally, the C trial is conducted on
farmers' fields to assess varietal suitability to
farm conditions. Since there are six climatic
zones in the country, a great diversity of conditions
is encountered. At present, tests within
a region may carry some different varieties at
different centers in the same trial series.
The principal dwarf variety grown in 1969-70
was Penjamo 62. Although this was fairly
heavily attacked in the previous year by stripe
rust, it yielded well and as a result was sown
on a wider acreage in 1969-70. Unfortunately,
it was attacked very early in the Caspian area
and this combined with a drier than usual year,
led to reduced yields. In the 1969-70 plan~ings
H.I.M. Government imported 1,000 tons
of Bezostaya to be grown primarily in Azerbaijan
in the northwest and 500 tons of Inia to
be grown in some of the southern areas and
in the Caspian Region. Bezastaya is susceptible
to stem rust, but has relatively good resistance
to leaf and stripe rust and to mildew.
Inia has good resistance to the three rusts,
but is susceptible to loose smut and to mildew.
Essentially, the Caspian region is Mediterra-
CIMMYT will work closely with Turkey's Cooperative Center of Research and Training. Here, Mrs. Sudatin
Demiroz shows experimental Inateri II to visiting scientists from other counfries at Aduapari, Turkey.
