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...

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....

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,...

A comparison of two methods of divergent mass selection for heading date in two winter wheat (Triticum aestivum L. em Thell) crosses

Creator:: Frederickson, Leslie John
Abstract:: Responses to two cycles of mass selection for heading date, followed by selfing or intermating, were studied in two diverse winter wheat (Triticum aestivum L. em. Thell) crosses. Selection was bidirectional, resulting in early and late populations for each mating system, cycle, and cross. The influence of mass selection for...

Assessment of resistance and inheritance to Barley Yellow Dwarf Virus disease (BYDV) in five wheat cultivars (Triticum aestivum L.)

Creator:: Tola, Jaime
Abstract:: Barley Yellow Dwarf Virus (BYDV) is a major disease of wheat. Unfortunately, unlike barley where the Yd2 gene provides adequate levels of resistance, the situation in wheat is more complex. This study was designed to provide information regarding: 1) evaluation of methods of measuring resistance among selected cultivars; 2) identification...

Identification and development of cultural practices for upland rice production systems for savanna soils of Colombia

Creator:: Leal-M, Dario
Abstract:: A great potential for increasing upland rice production exists in the savanna soils of Colombia. These vast areas are currently underutilized. However, they have good soil structure, flat topography, coupled with sufficient and well distributed rainfall, making savanna soils ideal for upland rice cropping system. The major constraints to upland...
