Research Highlights of the CIMMYT Wheat Program 1999-2000

Only a few cultivars performed well in both
regions. In the 1 st WWEERYT, ERYT6221 from
Mironovsk in Ukraine, derived from a mutation
program, was equal or better than checks in 13
locations. The parents, TXGH2895 and Trakia, were
lines from US, Texas, and Bulgaria. Agri//Bjy/Vee
had the second highest mean yield across locations
and was equal or better than the best of four checks
at 10 locations. Yuna, a winter hardy facultative
type from Krasnodar, Russia, also performed well
in both regions. In the 2 nd WWEERYT, five
cultivars, one each from Bulgaria, Texas, and
Romania and two from the IWWIP, performed well
in both regions.
In the CEE region, the highest mean yield was
obtained in the 1 st WWEERYT by cultivars from
programs located in CEE and TAM 200 from Texas
A&M. Yields of cultivars developed by the IWWIP
were different from those of the best entries, and
equal or slightly lower than that of the local check.
In the 2 nd WWEERYT, cultivars from CEE, Texas,
and the IWWIP had highest mean yields. The
IWWIP lines are derived from selections made in
Turkey.
