The experiments were carried out to evaluate the genotypic difference in low phosphorus (P) tolerance using 104 Tibetan wild and 20 cultivated barley genotypes. The results showed that plant growth and P accumulation were significantly reduced in the plants exposed to low P stress relative to normal P condition, while some genotypes of wild and cultivated barley increased root length and dry weight under low P stress. There were significant differences among the 104 Tibetan wild genotypes in growth parameters under low P stress, suggesting a wide genetic diversity among the tested genotypes. Significant genotypic differences in relative values of various physiological parameters and mineral nutrients in response to low P stress were also observed. Three Tibetan wild genotypes, XZ77, XZ99 and XZ167, and two cultivated genotypes, ZD 9 and ZAU 4 were identified as high tolerance to low P.
