Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

A study of methods of parental evaluation using testers to predict subsequent progeny performance in winter wheat (Triticum aestivum L.)

Creator:: Alexander, William Larry
Abstract:: The major objective of this study was to determine why certain winter wheat cultivars, when hybridized, will produce a greater proportion of desirable plants in subsequent, segregating generations. Three winter wheat parents were chosen as the experimental material, based on their known performance as parents. Yamhill and Pullman Selection 101...

Potential reciprocal differences for selected traits in six different F₁ wheat populations

Creator:: Stein, Ira Steven
Abstract:: Concerns about the possible reciprocal differences resulting from systematic crossings of winter and spring wheat gene pools prompted this investigation. If traits can be improved by simply reversing the direction of a cross, then identification of the best female parent in a cross would be helpful for breeding programs. Two...

Methods of evaluation, effects of intermating and results of one cycle of S₁ family recurrent selection in barley

Creator:: Mareck, James
Abstract:: The focus of this study was to determine if S₁ family recurrent selection might be successfully used for barley improvement. Objectives were: 1) to identify suitable methods of evaluating grain yield in small plots, 2) to study the effects of intermating on mean values and variances of selected agronomic characters,...

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....

Response of grain yield, plant height and kernel weight in three winter wheat crosses (Triticum aestivum, L. em Thell) to different methods of selection

Creator:: Salmeron-Zamora, Jose Juan
Abstract:: This study was undertaken to see if a method of handling segregating populations could be employed which combined the positive attributes of the traditional pedigree and-bulk methods. Derived F₅ lines from the pedigree, bulk, and what is identified as a modified bulk method, were obtained from three winter wheat crosses....

Nature of inheritance, genotype-environment interaction and association of selected agronomic characters in crosses of winter X spring wheats (triticum aestivum L. em Thell)

Creator:: Brajcich, P.
Abstract:: This investigation was motivated by the apparent increase in genetic variability resulting from the systematic combining of gene pools represented by winter and spring types of wheats. It was the objective of this study to provide information regarding the nature of this genetic variability for nine agronomic characters in populations...

Evaluation of four quality factors in a selected winter x spring wheat cross (Triticum aestivum Vill., Host)

Creator:: Schumaker, Karen Sue
Abstract:: The nature of the genetic variation associated with a cross involving winter and spring wheat parents for four quality factors was evaluated. Yamhill, a soft white winter wheat, and Inia 66, a hard red spring wheat, were selected as parents for this study. They represented distinctly different phenotypes for the...
