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...
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...
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...
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,...
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...
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 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...
