Grain yield and grain protein are often negatively associated in
wheat. When yield increases and grain protein decreases, there can be
an adverse effect on the milling and baking quality if the desired end
product is bread flour. It has been suggested that this inverse
association is the result of...
The Asian noodle market is responsible for the increased volume of wheat
imported to that region in recent years. Soft white wheat produced in the Pacific
Northwest is mainly used for baked products, whereas an Australian wheat,
Australian Standard White, is preferred for noodles. To enter this market soft
white-wheat...
Wheat (Triticum aestivum) is the major food crop produced
on the Anatolian Plateau of Turkey where due to limited
rainfall the farmers follow the traditional system of fallow
farming. They are presently producing an average of 1.15
tons of grain per hectare during the crop year. This rate
of production...
Effective chemical control of pollination would
provide an alternative to the cytoplasmic male-sterile
system in hybrid wheat (Triticum aestivum L.) production.
The objective of this study was to determine
concentration, formulation, growth stage of application
and genotypic effects on levels of induced pollen
suppression and subsequent natural out-crossing from
foliar...
The need to develop a shorter life cycle wheat cultivar which
would be more adapted to multiple cropping systems prompted this
study. Thus the following information was obtained.
Greatest variations in developmental patterns were found in the
stem elongation, booting, inflorescence emergence and anthesis for
five winter and five spring...
Parents and progeny populations from a cross of 'Stephens'x 'Tibet dwarf' were grown in a spaced-planted experiment to obtain information concerning the nature of inheritance and possible associations between grain yield and the components of yield. Agronomic traits measured on an individual plant basis were: heading date, days to maturity,...
This study was conducted to investigate the possible contamination
of foreign pollen at different stages of a wheat breeding
program. These included spaced planted F₂ segregating populations,
replicated yield trials and seed multiplication. The experimental
wheat materials consisted of four different F₂ populations, four
cultivars and two experimental lines.
Two...
Physical properties of gluten and pigment content are of primary importance in determining quality in durum wheat (Triticum turqidum L. var. durum). The objective of this investigation was to evaluate the contribution of different -y-gliadin protein subunits in durum wheat pasta quality as measured by the sodium dodecyl sulphate microsedimentation...
Parental and segregating populations derived from four winter x
spring wheat crosses were investigated to obtain information concerning
the inheritance and association of earliness, grain yield and yieldrelated
traits. Feasibility of selecting in early generations for these
characteristics was also evaluated. Four winter wheat cultivars
(Hyslop, Yamhill, Bezostaia 1, and...
Concerns about the genetic control and environmental influence
of various stages of development including the grain filling period,
and the relationship between early maturity and grain yield prompted
this study.
The experimental material consisted of two facultative and two
winter wheat cultivars. A dial!el cross, excluding reciprocals, was
also developed...
