Remarks 167 recombinant inbred lines (RIL) derived from a cross
between Tadmor (drought tolerant) and Er/Apm (susceptible)
was used. Tadmor, a two-row variety selected from a Syrian
landrace, is characterized by high yield stability (Grando
1989) and a high osmotic adjustment capacity (Teulat et al.
1997). Er/Apm, a two-row variety adapted to moderate
rainfall conditions (Acevedo 1987), was developed by ICARDA
(International Center for Agricultural Research in the Dry
Areas, Syria), Recombinant inbred lines were advanced by
bulk until the F4 generation at ICARDA and then by
single-seed descent until the F8 generation at CIMMYT
(Mexico).
Linkage analysis and map construction were performed by
using Map Manager QTX14 (Manly and Cudmore 1997) using the
Haldane function (Haldane 1919) to convert the recombination
frequencies to centiMorgans (cM).
Acknowledgments: Most of the mapping was done in ENSAM-INRA
Montpellier (France) by Beatrice Teulat with technical help
from Christiane Borries, under scientific supervision of
Dominique This. This work was funded by several grants from
INRA France and the French Ministry of Agriculture, and a
grant from the EC INCO-DC international cooperation with
developing countries program. Contributions to the RFLP data
were made by Mireille Khairallah (CIMMYT, Mexico) and
Philippe Leroy (INRA, Clermont-Ferrand, France). Ayman Diab
and Mark Sorrells (Cornell U., USA) added 33 markers
corresponding to candidate genes and ESTs and performed the
final map construction.
