Single cross progeny evaluation in tall fescue, Festuca arundinacea, Schreb

Creator:: Cáceres, Oscar
Abstract:: All possible single crosses from three different maturity groups of 27 selected parental genotypes of tall fescue were established in a randomized block experiment to be evaluated in 1962 for five agronomic characters: height, width and maturity per plant; self -seed yield per plant; and forage yield per plant. For...

A comparison of progeny testing methods and estimates of combining ability for seed yield and associated variables in tall fescue (Festuca arundinacea, Schreb.)

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...

Some factors that affect pollination and seed formation in alfalfa, Medicago sativa L

Creator:: Bradner, Norman Richard
Abstract:: The objectives of this study were (a) to measure the amount of cross-pollination caused by three bee species at 10, 20 and 40 rods distance from a foreign pollen source, (b) to measure the effects of bee species, planting pattern and season on broad sense heritability estimates for seed yield...

The breeding behavior of forage yield in two populations of tall fescue, (Festuca arundinacea, Schreb.)

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...

Heritabilities and associations of seed yield components and seed yield in tall fescue (Festuca arundinacea, Schreb.)

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...

Studies on the methodology of crossing and selfing in Lolium multiflorum

Creator:: Bergman, Jerald Wilmer
Abstract:: Studies were conducted to determine the effectiveness of a biological pollen barrier of rye, Secale cereale, in preventing out-crossing between Lolium multiflorum genotypes in each of the 300 crossing blocks established in this experiment. Fluorescent tests of seeds of open-pollinated and single-crossed progeny of four annual ryegrass sources were used...

Evaluation of methods of progeny testing in tall fescue seed production (Festuca arundinacea, Schreb.)

Creator:: Thomas, Johnny Ray
Abstract:: Seventeen parental clones were selected, from 9,000 plants, on the basis of self-sterility, seed and forage yield potential using phenotypic ratings, crude protein and chromogen content. The parental clones were divided into two populations based on date of maturity. Group I was intermediate in maturity and had nine parental clones,...
