SDS-PAGE was used to determine the variation in high molecular weight glutenin subunits (HMW-GS) alleles present in 170 landraces of common wheat from Sindh, Balochistan and NWFP in Pakistan. Three alleles for
, six alleles for
and four alleles for
were detected. These included three new alleles, namely
, which had not previously been found in landraces of Pakistani wheat. Furthermore,
, which are considered to be endemic alleles in Pakistan and Afghanistan, were both detected from Balochistan. Twenty genotypes were identified based on combinations of alleles at the three
loci. The present study showed that Pakistani landraces of common wheat have maintained a broad diversity of HMW-GS alleles, and that they may serve as genetic resources to improve wheat varieties adapted to Pakistani climatic and edaphic conditions.
