Creator:: Echeverri, Silvio
Abstract:: Eight genotypes of tall fescue were selected from a plant population consisting of 9000 individuals. Selection was based on early maturity, self-sterility, seed and forage potential, and nutritive value. Parental clones, single cross, open pollinated, self pollinated and polycross seeds were organized into a randomized block experiment with five replications...

Abstract:: Response to heterosis for plant height, anthesis date, panicle number, seed yield, and fall vigor rating was determined in a tall. fescue group selected for diverse morphology, origin, and anthesis date. Parents, single-cross progeny (SX), and first generation selfed progeny (S₁) were included in the study. Each experimental plot consisted...

Creator:: Matheson, Keith Isom
Abstract:: The single-cross and most F₂ progenies of 19 genotypes of tall fescue (Festuca arundinacea, Schreb. ) were used to study the breeding behavior of forage yield. Parental genotypes were selected for high self-sterility, high chromogen and high crude protein. These were studied in two groups of nine intermediate and ten...

Creator:: Thomas, Johnny Ray
Abstract:: Estimates of heritability and associations of tiller number, seed number, seed weight, and seed yield were determined in two groups of tall fescue. Group E was early maturing and had eight parental clones, while group I was intermediate in maturity and had nine parental clones. The parents and five progeny...
