Abstract
restricts yields on 40,0UO,OOO hActares nf 1rr1gated land,
whirh is approximately nne-third of the Irr1gated land on earth,
tDernstein 19 75). DevelopmPnt of salt tolerant crop cultivars
would complement salt management programs to help max1-
m1ze yields in these area.
Breeding for drought and salinity resistance in wheat,
means breeding for yield in environments where these two factors
are considered as limiting production factors.
Improvements in yield come from recombination of genes
by crossing different genotypes, followed by selection of the
progeny possessing the desired agronomic features and a higl1er
yield level.
In this conventional ~reeding method, there are questions
of the relationship betweero F

The present wurk was undertaken to study the effect of
Jr·o~ght and salinity on genetic parameters for some agronomlc
traits that could guide wheat breeder 1n breeding improved
varieties under those conditions.
