The effects of foliar diseases and irrigation on root development, yield and yield components of wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1985)
Studies were conducted on three field trials of wheat cv. Kopara to investigate the lack of compensation by later determined components of yield because of early disease constraints. The investigation was based on the ...
Yield structure and pre-anthesis carbohydrate status of wheat
(Lincoln College, University of Canterbury, 1980)
In the 1977-78 and 1978-79 seasons, three field experiments were conducted on a deep moisture retentive soil to investigate the
responses of wheat yield to various seeding rates, rates and times of
N application, and ...
Inheritance studies in four New Zealand wheat cultivars
(Lincoln College, University of Canterbury, 1980)
Inheritance and correlations of yield, yield components, and morpho-physiological and agronomic characters involving four parent diallel crosses of F₁ and F₂ generation were studied in Kopara, Ruru, Hilgendorf and Oroua. ...
Response surfaces of growth and yield of wheat
(Lincoln College, University of Canterbury, 1979)
In the 1976-77 and 1977-78 seasons four field experiments using a three factor central composite second order design in incomplete blocks were conducted to quantify the responses of autumn-sown wheats established at five ...
Tiller population dynamics in wheat
(Lincoln College, University of Canterbury, 1978)
In field-sown wheat grown in Canterbury, variation in the density of ears accounts for most of the differences between grain yields (Dougherty 1973; Scott 1978; Scott et al. 1977). Ear number is a component of yield which ...
Inheritance and selection in two New Zealand wheat crosses
(Lincoln College, University of Canterbury, 1982)
The objective of this study was to evaluate the inheritance of yield per plant and yield components, their responses to single plant selection in F₂, and line selection in F₃ of the two crosses, Hilgendorf x Oroua and ...
Environmental control of tillering and yield of wheat
(Lincoln College, University of Canterbury, 1985)
Four experiments were conducted in controlled and field environments from 1982 to 1984 to establish relationships between dry matter growth rate and tillering, yield components and grain yield of wheat.
In the first ...
Epidemiology and crop loss assessment for disease management in winter wheat (Triticum aestivum L.)
(Lincoln College, University of Canterbury, 1984)
The epidemiology of Mycosphaerella graminicola (Fuckel) Schroeter was studied for two seasons and the role of ascospores as primary inoculum of the disease was examined as a basis for the development of control measures. ...
Components of grain yield in wheat : a thesis submitted for the degree of Doctor of Philosophy in the University of Canterbury [Lincoln College], New Zealand
(Lincoln College, University of Canterbury, 1977)
Between 1972 and 1976 a series of field experiments were conducted to investigate the factors limiting grain yield in
wheat (Triticum aestivum L). Spike population restricted yield
when it was below about 500 spikes/m² ...
