| Abstract/Contents: | "We are very encouraged by the progress made during the last year. New breeding material was added from California, Ohio, Minnesota and Europe. Seed collections have been made from original crosses and have proven to possess some desirable characteristics. Superior genotypes have been advanced one to five generations. Two hundred fifty-one selections of Poa annua and Poa supina were germinated and grown in the greenhouse for transfer to field space planting. There was also the space planting of 1200 plants representing 145 selectins established in the field in 1985. Overwintering, spring green-up, summer and fall performance evaluations were also made. A field planting of stolons of 15 different materials was established and maintained at putting green height. One clone [10-C] in particular stood out during the spring, summer and fall due to a dark green color, dense turf and limited flowering. At least three other clones exhibited limited flowering habits. One hundred twenty-one F2 plants were started in the greenhouse and transferred to field planting for observation of growth characteristics and genetic variation. Twenty-two selected clones were grown in the greenhouse and interplanted into existing collar height conditions in the field to evaluate competitive ability, growth habit under competition and disease susceptibilities. Breeding research in incompatibility and technique development in emasculation of florets, flower suppression, stolon viability in storage, hardiness, tissue culture, selections and other practices are being explored. The project is at a point where increased support could be very productive in terms of shortening the time to introduction of an improved Poa annua. Research progress is being made which is beyond what could be normally expected under current support conditions. The 1986 results have been very satisfying." |
