IMPROVEMENT OF KENTUCKY BLUEGRASS THROUGH SELECTION AND BREEDING

THE DEVELOPMENT OF IMPROVED-ADAPTED BLUEGRASSES, WHICH WOULD CONTRIBUTE TO MORE UNIFORM TURF AND LOWER PLANT HEIGHT, THUS LESS FREQUENT MOWING, WOULD PROVIDE A SOLUTION TO HIGHWAY MAINTENANCE PROBLEMS AND OFFER A REDUCTION IN MAINTENANCE COSTS. THIS RESEARCH INVESTIGATED THE POSSIBILITY OF REDUCING THE TIME AND EXPENSE INVOLVED IN BREEDING AND SELECTING SUPERIOR UNIFORM TYPES THROUGH COUNTING OF CHROMOSOMES. THE THESIS PROPOSED WAS THAT BLUEGRASSES WITH LOW CHROMOSOME NUMBERS WOULD BE APOMICTIC, RESULTING IN UNIFORM REPRODUCTION. SEEDLINGS WOULD REMAIN TRUE TO THE PARENT THROUGHOUT CONTINUED SEED PRODUCTION. THE RESEARCH CONCLUDED, HOWEVER THAT THERE WAS LITTLE BASIS TO SUPPORT THIS PROPOSAL. LOW CHROMOSOME NUMBERS DID NOT SERVE AS A KEY TO SELECTING UNIFORM APOMICTIC VARIETIES. THE PERFORMANCE OF SELECTIONS PLANTED ON HIGHWAY ROADSIDES ARE REVIEWED AND A SELECTION OF THIRTEEN (13) SUPERIOR TYPES THAT WILL BE FURTHER EVALUATED AS THE INITIAL PORTION OF A NEW RESEARCH PROJECT IN FY 73 ARE DISCUSSED. FINAL SELECTIONS OF THE BLUEGRASSES TO BE RECOMMENDED FOR SEED INCREASE AND EXPANDED TESTING ARE PLANNED FOR THE SPRING-SUMMER OF 1973 AS PART OF THAT PROJECT.
