The effect of raised bed culture on winter survival of ten pea
genotypes (Pisum sativum L.), differing in inherent cold hardiness
and growth habit, was studied under two climatic conditions: a moist
semi-maritime winter (Corvallis, Oregon) and a cold continental
winter (Weston, Oregon). An assessment of winter injury was based...
California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...
A glaze storm of exceptional severity was seen in the Corvallis
area, January, 1942. The weight of ice that accumulated in the
crowns of young-growth Douglas-fir trees caused widespread top
breakage in many stands lying in the broad path of this storm.
Early research on this phenomenon showed the majority...
The easy picking characteristic, expressed as low pod detachment force (PDF),
offers a way to decrease pod damage in bush green beans mechanically harvested for
processing and fresh market, and makes hand picking easier and faster. This study was
undertaken to examine inheritance in a cross of two green bean...
The inheritance mode of pea-resistance to the Lentil
Strain of Pea Seedborne Mosaic Virus (PSbMV-L) was
studied. In addition, commercial pea cultivars, Plant
Introduction (P.I.) lines and Oregon State University
(OSU) breeding lines were tested for susceptibility to
this virus. These lines were also tested for their
reaction to Bean...
Three provisional species are described as new: Leucogaster
couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida
is transferred to Leucogastef, completing the transfer of all
Leucophlebs species to Leucogaster. L. columellatus is transferred
to Sclerogaster. L. longisterigmatus is synonymized with
L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...
The inheritance of ten characteristics of sweet corn was studied
by quantitative genetic analysis. Characters studied were tassel
date, silk date, plant height, ear height, shank length, husk extension,
tip blanking, number of kernel rows, ear length, and weight of the
first ear.
Diallel crosses were made between seven inbred...
The expression and inheritance of a leaf distortion of beans was
studied in a group of the Oregon State University breeding lines and a
commercial cultivar. Of seven parents involved, two were without distortion
and classified normal, and the remainder were affected by
various degrees of distortion. The distortion affected...
