| Abstract/Contents: | "Poa annua is one of the world's most widely distributed invasive weed species. Research continues at Penn State University to develop improved Poa annua cultivars for putting greens. This project made much progress toward that goal and much infoormation [information] has been learned about this highly variable species. When the annual bluegrass breeding program was initiated in July, 1994, thousands of Poa annua samples were collected from existing golf course greens. To date, the project has collected and evaluated tens of thousands of Poa annua plants. Poa annua plants evolve an increasingly perennial nature as the level of turfgrass management increases. This process continues on the golf green until plants eventually become entirely perennial and losethe ability to set viable seed all together. Selection pressures of the green environment are so intense that on greens as young as 60-years-old, it is common to observe a special type of Poa annua known as dihaploids. Dihaploids occasionally produce a flower stalk, but are absolutely seed sterile and thus exist entirely as vegetative perennials. Such dihaploids represent some of the densest, finest, and highest turf quality strains yet observed. The main obstacles that need to be overcome for the successful cultivation of Poa annua seed for the commercial market are 1) low seed yield, 2) the indeterminacy of seed maturity, and 3) the control of undesirable forms of Poa annua within seed production fields." |
