A diallel cross consisting of ten parents was grown on the
Hyslop Agronomy Farm near Corvallis, Oregon, in order to obtain
estimates of the gene action contributing to yield and its components
in wheat. Gene action estimates were obtained by two methods of
diallel analysis and from narrow sense heritability...
Studies were conducted to verify the existence of IAA in wheat
seedlings and to determine the effect of (2-chloroethyl)-trimethyl-ammonium
chloride (CCC) on the IAA content of club wheat,
Triticum aestivum compactum, variety Omar. The shoots of CCC-treated
and untreated wheat plants were extracted with ethanol, the
plant extract purified, separated...
Wheat is an important cereal crop in the Willamette Valley of
Oregon and the stiff-strawed, high yielding winter varieties are
the predominate types grown although spring varieties are not uncommon.
Because of the mild, often open winters; present in the
Willamette, it is not unusual to be able to seed...
The purpose of this study was to determine the amount of
heterosis in three complex traits in barley and to investigate the
concept of component interaction as a means of producing heterosis.
The complex traits were grain yield, total leaf area, and malting
quality.
Seven varieties of spring barley were...
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...
The objective of this study was to investigate the low seed
germination of 12 varieties of Oregon grown monogerm sugar beet,
Beta vulgaris L., using several methods to determine the germination
potential. The methods were: (1) X-ray radiograph examination,
(2) standard laboratory germination following official rules,
(3) laboratory germination by...
