35. Seed Research of Oregon Improving Turfgrass through Research Why Blends and Mixtures Kentucky bluegrass apomictic Single genotype - other turfgrass species are mixture of genotypes Vegetative cultivars comparison Vegetative bentgrasses Vegetative bermudas, zoysias, St. Augustine Merion Kentucky bluegrass - stripe smut Not just for disease resistance Winter and spring growth, shade tolerance

36. Seed Research of Oregon Improving Turfgrass through Research Science and nonscience of blends Kentucky bluegrass (Vargas and Turgeon, 1980. Proc. Third ITRC 45-52.) Melting-out resistance of blend of two cultivars intermediate between same cultivars in monostands Inoculum from susceptible cultivar reduced resistance of resistant cultivar Blends of two cultivars generally show resistance intermediate between each alone

37. Seed Research of Oregon Improving Turfgrass through Research Science and nonscience of blends Early blend analysis - Dr. Funk, Rutgers Sprigged out plants to ID Aggressive types dominated Aggressive types based on invasion in plots New DNA techniques allow blend analysis (Lickfeldt et al, 2002. Crop Sci. 42:842-847.) 3-way blend - Unique, Midnight, Blacksburg Different management and % of each at seeding Final composition, 40% U, 46% M, 14% B

38. Seed Research of Oregon Improving Turfgrass through Research Texas X Kentucky bluegrass Texas bluegrass heat and drought tolerant, extensive and deep rhizomes Kentucky bluegrass turf quality 1st generation low fertility, low germination Backcrossed to Kentucky bluegrass More extensive rhizomes Greater heat and drought tolerance Must evaluate for diseases, germination vigor, apomixis

39. Seed Research of Oregon Improving Turfgrass through Research Texas x Kentucky bluegrass Many first hybrids poor germination Thermal Blue = HB 129 = BH00-6002 Improved establishment High shear strength Excellent rhizomes = good recovery Good wear tolerance in Ohio - not high Rutgers Have done good in some fairway trials Additional new hybrids with good establishment, high drought tolerance

41. Seed Research of Oregon Improving Turfgrass through Research Perennial ryegrass Advantages in mixtures Quick establishment Very dark green color Resistant to different diseases than KBG/TF Endophyte-enhanced Disadvantages in mixtures Overdominate other components Bunch-type growth Reduced stress tolerance

42. Seed Research of Oregon Improving Turfgrass through Research Perennial ryegrass Advantages and varietal needs Rapid establishment - Best species for establishment during play Winter-active growth for many uses Daylength-dependent dwarf types less suitable Decumbent, spreading growth - superior in Europe for repair Reduce nitrogen requirements Best in regular trials may not be best in wear trials

43. Seed Research of Oregon Improving Turfgrass through Research Benefits of Perennial ryegrass Benefits of adding endophyte-enhanced ryegrass to Kentucky bluegrass Richmond and Shetlar Percentage of perennial rye added to blue Above 40% bluegrass webworm protection Hairy chinch bug damage down more perennial ryegrass added No documentation of percentage in other species Complex of different species and different endophyte strains

49. Seed Research of Oregon Improving Turfgrass through Research Temperature and Leaf Wetness

50. Seed Research of Oregon Improving Turfgrass through Research What we know Gray leaf spot spores primarily airborne and spread by mowers, equipment (How did it get to CA?) Gray leaf spot overwinters as dormant mycelium in dead tissue - cold winters can reduce initial innoculum Long periods of leaf wetness under hot conditions favor the disease Initial innoculum builds up under lower temperatures then it explodes Often first occurs in shady, wet areas

51. Seed Research of Oregon Improving Turfgrass through Research What we know Initial symptoms are an off-color, wilted appearance Often mistaken for drought stress so irrigation is applied increasing period of leaf wetness = more disease Seedlings tend to be more susceptible than mature plants - could partially be due to maintenance of wet conditions in seedbed High nitrogen makes it worse Primo in spring can make it worse, but not in fall

52. Seed Research of Oregon Improving Turfgrass through Research What we know Fungicide control QoIs - Heritage at high rate good with high disease pressure, Compass at label rate sometimes has reduced control Benzimidazole or Clearys 3336 good except highest pressure Always add in a contact fungicide for spores Resistance already reported to QoIs - switch to fungicide with moderate activity for part of year Best long term solution lies in breeding for resistance

53. Seed Research of Oregon Improving Turfgrass through Research Ryegrass and GLS Further studies and needs Pyricularia grisea (Magnaporthe grisea) can rapidly change races Currently unknown number of races in US Do resistance genes work against all current races? Some variability in results from seedling trials in NJ and mature plants in MD - high resistant types remain resistant New germplasm sources - many resistant genes from European collections Genetic studies currently being done
