Abstract

The current study is an effort to identify the best wheat genotype, which can tolerate drought in arid environmental conditions of Lasbela district, Balochistan. For this purpose, five genotypes of wheat, viz., Amber, Mehran, Khirman, Imdad-05 and Sehar-2006 were selected.  These five wheat genotypes seeds were sown in winter of 2015-16 at Lasbela University campus for 45 days. The biomass, leaf size, leaf weight and moisture constituents of leaves were collected when these varieties started to show the signs of drought stress in the form of wilting. The results showed that the Sehar-2006 is a promising genotype when grown in Lasbela’s local environmental condition compared with other genotypes. On the other hand, Mehran is one most vulnerable genotype when grown in this region. Three genotypes (Imdad-05, Khirman and Amber) showed mix response in relation to water stresses. The research highlighted that Sehar-2006 is the best species to be cultivated by the farmers and it can provide good vigor and high production for future development.
