The effects of tillage systems and seeding dates on grain yields of wheat (Triticum aestivum Vill., Host) on the Anatolian Plateau of Turkey

Creator:

Zinn, Thomas G.

Abstract:

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...

Use of combining ability estimates to identify the genetic potential of selected winter parental lines (Triticum aestivum L.em Thell)

Creator:

Masood, Muhammad Shahid

Abstract:

A major factor limiting the efficiency of plant improvement programs is the lack of knowledge as to which parental combinations to make when working with quantitatively inherited traits. The primary objective of this study was to provide information regarding the use of combining ability analysis to predict which cross combinations...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:

Albahouh, Muhammed S.

Abstract:

To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

Possible association of grain protein content, harvest index and biological yield in winter wheat populations

Creator:

Costa, Jose Maria

Abstract:

A negative relation between grain protein content and grain yield is frequently observed in wheat (Triticum aestivum L. em Thell) i.e. as grain yield increases, grain protein decreases. It has been suggested that the inverse relation between grain yield and protein is in part the result of developing high yielding...

Possible compensations of the components of grain yeild in wheat (Triticum aestivum L.) as influenced by genotype by environment interactions

Creator:

Bedoshvili, David

Abstract:

Despite many investigations genotype by environment interaction remains one of the least understood factors in plant improvement. Understanding genotypic differences responsible for such interactions could assist in making more informed breeding decisions. The components of yield being less complex than grain yield per se may be useful for selection to...

Assessment of genetic resistance to strawbreaker foot-rot (Pseudocercosporella Herpotrichoides) in selected winter wheat (Triticum aestivum L.) cultivars

Creator:

Encinas-Mungarro, Andres

Abstract:

Strawbreaker foot-rot is a major limiting factor to cost efficient winter wheat production in the Pacific Northwest. Development of resistant cultivars has been hindered by the lack of adequate levels of genetic resistance and screening techniques which can consistently detect desired genotypes. Studies were conducted to determine if the reported...

Possible associations of soluble carbohydrates with chemical desiccation and drought resistance in winter wheat

Creator:

Cerono, Julio Cesar

Abstract:

Drought is a major limiting abiotic stress influencing wheat production in many parts of the world. The erratic nature of water deficits makes breeding and selection for drought resistance deficient. In environments with late season drought stress, yield losses are usually associated with kernel abortion or reduction in kernel growth....

Pre-harvest sprouting tolerance of a synthetic hexaploid wheat (Triticum turgidum L. x Aegilops tauschii Coss.)

Creator:

Rosa, Andre Cunha

Abstract:

Pre-harvest sprouting in wheat costs farmers millions of dollars every year. Pre-harvest sprouting tolerance (PST) has minimized this problem, but improvement of PST is still necessary. Synthetic hexaploid wheats (synthetics) have been used as sources of genes coding for many useful traits. Two studies evaluated the PST of a synthetic...

Production of haploid plants in selected winter wheat genotypes through anther culture and intergeneric crosses with maize

Creator:

Mendoza, Maria Graciela

Abstract:

A higher level of efficiency in the production of doubled-haploids must be achieved if this procedure is to be beneficial in plant improvement. Of equal importance is the development of protocols, which are not genotypic specific and result in progeny that represent a random sample of gametes from the parental...
