| Abstract/Contents: | "Aluminum toxicity is probably the most important growth limiting factor in acid soils for many turfgrasses. The genetic diversity among turfgrass cultivars for Al tolerance is not well known. One hundred-fifty Kentucky bluegrass (Poa pratensis L.) genotypes (cultivars, selections, and breeding lines) belonging to seven types were screened for Al tolerance under greenhouse conditions using solution culture, sand culture, and acid Tatum soil (a subsoil commonly used for Al tolerance screening). An Al concentration of 320 μM and a pH of 4.0 were used in solution screening and sand screening. The acid Tatum soil had 80% exchangeable Al and a pH of 4.4. The grasses were seeded to five weeks before harvesting. Differences were identified among cultivars and the seven types by measuring relative growth. Based on the rank average of the three screening methods, 'Barzan', 'Viva', 'Nassau', and '1757' were the most Al tolerant cultivars while 'Ginger', 'South Dakota Cert.' and 'Ronde' were the least. Among the seven types, BVMG types were most Al tolerant while Midwest ecotypes consistently exhibited the least Al tolerance. The results indicate that Kentucky bluegrass cultivars vary genetically in Al tolerance and there is potential to improve the tolerance with breeding and to refine management recommendations regarding soil pH." |
