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 of some components of test weight in Soft White wheat
revealed distinct subclass differences. Wheat kernels of Soft White
more completely occupied a given volume than did kernels of White
Club. The Soft White kernels were larger and had a higher density
than the White Club kernels. Because of...
An experiment was conducted to examine the responses to
selection for high and low rate of gain in the mouse under a system
whereby inbreeding was maximized. Rate of gain was measured by an
index designed to include gains in both the pre- and postweaning
periods with the gains in...
The effect of different soil moisture levels on the amount and
location of NO₃ -N accumulation in the soil profile were studied.
The cultivars used in this study were Mcdermid, a soft white
winter wheat, and Hudson, a medium early winter barley.
Moisture treatments simulating dry, normal and wet fallow...
Four winter and four spring barley cultivars along with their F₁
hybrids were grown on the Hyslop Agronomy Farm near Corvallis, Oregon,
a high rainfall site (over 1000 mm annually) located in the Willamette
Valley. The experiment consisted of four replications. Ten seeds of
each F₁ and parents were seeded...
With the development of new selective herbicides and the frequent
change in commercial wheat cultivars, information is needed as to the
possible interaction between cultivars and herbicides. The responses
of five genotypically diverse wheat cultivars (Bezostaya, Daws, Maris
Hobbit, Stephens and Yamhill) to diuron [3-(3,4-dichloropheny1)-1,1-
dimethylurea], diclofop methyl 2-[4-(2,4-dichlorophenoxy)phenoxy]
propanoate...
Higher grain yield is a key objective in barley (Hordeum vulgare. L) breeding.
Despite extensive research on the genetics of yield and its components, selection for
yield per se is still the most extensively employed because of negative relationships
among components, modest correlations between yield and any particular component,
and...
