Introgression between jointed goatgrass (Aegilops cylindrica) and wheat (Triticum aestivum)

Creator:: Snyder, Jeremy R.
Abstract:: Hybrids between wheat and jointed goatgrass have long been presumed to be sterile; however, seed were found on hybrid plants in 1990. Field studies were conducted in 1995 and repeated in 1996. One to ten hybrid plants were planted in variable populations of wheat and jointed goatgrass to determine the...

The development and analysis of sequence-based DNA markers in sunflower for DNA fingerprinting and candidate gene analysis

Creator:: Hongtrakul, Vipa
Abstract:: Molecular DNA markers have become widely used in all areas of genetic research. The objectives of this thesis were to develop polymorphic markers in sunflower and utilize the markers for genetic and candidate gene analyses. Amplified fragment length polymorphism (AFLP) markers were used to estimate genetic similarities and assess the...

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...

Nuclear and mitochondrial DNA polymorphism and phylogeny in the California closed-cone pines

Creator:: Wu, Junyuan
Abstract:: We studied genetic polymorphism and phylogeny using nuclear random amplified polymorphic DNA markers (RAPDs) and mitochondrial DNA (mtDNA) restriction fragment length polymorphisms (RFLPs) in the three California Closed-Cone Pines: Pinus attenuata Lemm., P. muricata D. Don, and P. radiata D. Don. A total of 343 to 384 trees derived from...

Mapping and introgression of disease resistance genes in barley (Hordeum vulgare L.)

Creator:: Toojinda, Theeryut
Abstract:: Molecular tools, coupled with unique germplasm stocks and rigorous phenotyping, are useful for developing a better understanding of qualitative and quantitative disease resistance genes in plants. The identification of molecular markers linked to all types of resistance genes provides opportunities for implementing a range of resistance breeding strategies, ranging from...

Quantitative trait locus mapping of yield and yield components in barley (Hordeum vulgare L.)

Creator:: Traore, Abdoulaye
Abstract:: Higher grain yield is a key objective in barley (Hordeum vulgare. L) breeding. Despite extensive research on the genetics of yield and its components, selection for yield per se is still the most extensively employed because of negative relationships among components, modest correlations between yield and any particular component, and...

Identification of a mechanism underlying heritable subfertility in roosters homozygous for the rose comb allele

Creator:: McLean, Derek J.
Abstract:: The overall objective of this research was to define the cellular basis underlying heritable subfertility in roosters homozygous for the rose comb allele (R/R). Fertilization in the hen is preceded by the ascension of motile sperm through the vagina and sperm sequestration within sperm storage tubules (SST). The objective of...
