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...
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...
Four agronomically and genetically diverse winter wheat parents
were utilized as the experimental organisms. Atlas 66 and NB 68513
were selected as cultivars with a high and stable protein content when
grown under different environmental condidtions. They are intermediate
for grain yield when grown in the Pacific Northwest. Yamhill
and...
The genetic variability in and association between 14 traits that affect maturity, yield, and chemical properties of its product. The plant characters measured were: vigor, flowering date, harvest date, yield, lateral length, nodes per lateral, cones per lateral, cones per vine, cone weight. Alpha-acid and beta-acid content of the cone,...
Experiments were conducted to determine identification methods
that could be used to differentiate annual and perennial plant types within
the species Poa annua L. Thereafter, Poa annua plants were collected
from numerous turfed areas in three Northern Pacific Coastal
regions and identified as annual or perennial biotypes.
It was found...
