Creator:: Tragoonrung, Somvong
Abstract:: Hill plots and near infrared reflectance (NIR) spectroscopy were investigated as breeding tools to facilitate doubled haploid recurrent selection for malting quality characters in spring barley. Main objectives of this research were to i) compare hill and row plot expression of agronomic and malting quality traits in an array of...

Creator:: Young, William C. (William Clyde)
Abstract:: Seed yield in perennial ryegrass is the product of yield components that develop during the life of the plant. Crop yield potential is defined by the number of fertile tillers, spikelets per spike, and florets per spikelet. It has been shown that perennial ryegrass realizes only a small percentage of...

Creator:: Camacho Casas, Miguel Alfonso
Abstract:: The effects of some soil- and foliar-borne biotic factors on grain yield and the components of yield were evaluated using five winter wheat varieties sown at two dates. Within each planting date, varieties were grown under four different combinations of two soil treatments (fumigation and nonfumigation) and two foliar treatments...

Creator:: Hazar, Necati
Abstract:: Ten wheat crosses (four winter x spring and six winter x winter) involving F₃ and F₄ generations and their respective winter parents were used to determine whether the early generation selection would be effective for kernel hardness and grain protein content. In 1980, twenty individual F₂ plants were selected with...

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....

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...
