Abstract
Boron tolerance in eleven wheat varieties was studied in a pot culture experiment. The tolerance was related to varietal efficiency for B uptake and to their B requirement. Variety Blue Silver appeared to be most tolerant followed by Punjab-85, Pak-81, Kohinoor-83, LU-26, Shalimar, Sutlej-86, Chakwal-86, Faisalabad-85, Barani-83, Faisalabad-83. Plant tolerance of B was not associated with their Ca content or Ca/B ratio
