RELATIONSHIP OF EXCISED-LEAF WATER LOSS RATE AND YIELD OF DURUM WHEAT IN DIVERSE ENVIRONMENTS

The rate of water loss (RWL) from excised leaves has been proposed as a screening technique to identify wheat genotypes adapted to dry growing conditions. The relationship of RWL and grain yield was studied in 100 durum wheat (Triticum turgidum L. var. durum) genotypes grown at two locations in Canada and three locations in Syria. Fifty of the genotypes were chosen on the basis of low RWL and 50 on the basis of high RWL. Growing season...
