| Abstract/Contents: | "Tall fescue [Lolium arundenaceum, (Schreb.) Darbysh.] (2n=6x=42) is a cool season, perennial, self-incompatible, bunch type turfgrass which spreads primarily by erect tillers. It is widely used in athletic fields, home lawns, golf course roughs and sod production; however, its bunch type growth habit can limit its utility in other areas. Some genotypes in tall fescue are reported to have short rhizomes and/or a rapid tillering rate, suggesting that it may be possible to produce tall fescue cultivars with these traits by selective breeding. Tillers improve longevity, turf density, spreading ability, wear tolerance and compactness, while rhizomes increase recuperative ability from damage, help in persistence under drought and temperature extremes, and improve sod strength. The growth habit of several tall fescue genotypes was classified as: bunch type which spread by erect tillers; rapid tillering type which spread by rapidly forming lateral tillers; or rhizome type which produce rhizomes along with tillers. Two genotypes from each growth type were selected and allowed to cross in the greenhouse in a diallel crossing scheme which includes all possible combinations of crosses between these six genotypes. Progenies were planted in the field in randomized complete block design with four replications. Data was analyzed for turf density and ground coverage (cm2) to estimate narrow sense heritability, maternal effect and heterosis in tall fescue. The narrow sense heritability estimate was higher for turf density than ground coverage. The crosses between bunch types with rapid tillering types exhibited significant heterosis and maternal effects for turf density and ground coverage. Diallel analysis proved useful to evaluate the performance of parents based on progeny tests, selecting superior parents, and improving breeding efficiency for the rapid tillering rate in tall fescue." |
