Genetics of partial incompatibility and improvement of haploid production in Hordeum vulgare L. x H. bulbosum L. crosses

Creator:: Chen, Fu-chiang and Chen, Fuqiang
Abstract:: The production of barley (Hordeum vulgare L.) haploids by crossing with H. bulbosum is a widely used tool in breeding and genetics. Certain barley genotypes have low seed set in this interspecific cross, a phenomenon known as partial incompatibility. Haploid production efficiency and gamete sampling are important issues with the...

Topometric Analysis for High-throughput Phenotyping of Seed Shattering in Perennial Ryegrass (Lolium perenne L.)

Creator:: Tubbs, Travis B.
Abstract:: Seed shattering is a constraint to improvement of seed yield in Lolium perenne L. and as a result, seed retention is an essential trait for this valuable crop. Field studies were conducted near Corvallis, OR in two years (2017-2018 and 2018-2019) to identify genetic variation for seed retention and to...

Pathogenic variability and adaptation of Septoria tritici to different wheat cultivars

Creator:: Ahmed, Hafiz Uddin
Abstract:: Experiments were done to determine pathogenic variability and pathogenic adaptation of Septoria tritici to different wheat cultivars. Fifteen S. tritici isolates from California, Oregon, and Texas were evaluated on seedlings of two sets of geographically diverse wheat cultivars under greenhouse conditions. Significant isolate effects, cultivar effects, and isolate X cultivar...

Identification of quantitative trait loci underlying kernel extra-softness and related traits by linkage and association mapping in wheat (Triticum aestivum L.)

Creator:: Wang, Guomei
Abstract:: Kernel hardness (KHA) is a major factor determining break flour yield (BFY) and end-use quality of common wheat (Triticum aestivum L.). Within the soft wheat class, genotypes with consistently softer grains than common soft wheat are considered to be 'extra-soft'. In addition, 'extra-soft' wheats have greater BFY than common soft...

Multi-location analysis for the identification of quantitative trait loci underlying disease resistance against Cephalosporium gramineum and Puccinia striiformis f. sp. tritici by linkage mapping in wheat (Triticum aestivum L.)

Creator:: Vazquez, Maria Dolores
Abstract:: Wheat (Triticum aestivum L.) is one of the major crops produced in the U.S. Pacific Northwest, a region known for its wheat production for international export. Wheat production in the region is threatened by diseases such as Cephalosporium stripe and stripe rust. Cephalosporium stripe is a vascular wilt disease of...

Phenotypic response and quantitative trait loci for resistance to Cephalosporium gramineum in winter wheat

Creator:: Quincke, Martin C.
Abstract:: Cephalosporium stripe (Cephalosporium gramineum) is an important disease limiting adoption of conservation tillage practices in the Pacific Northwest. The disease can cause severe loss of grain yield and quality in winter wheat (Triticum aestivum L.). Modified cultural practices can reduce disease incidence, but are not always dependable because of variation...

RFLP analyses of interspecific hybrids of Phaseolus

Creator:: Kuo, Mei
Abstract:: Gene transfer via interspecific hybridization within Phaseolus has been limited by abnormal hybrid development and the rapid loss of hybridity in subsequent generations. The most advanced embryo development occurs in P. vulgaris x P. coccineus where mature seeds form. However, the reciprocal cross still results in abnormal embryos unable to...
