Origin, Rise And Development Of American Upland Cotton And Their Status At Present. Second Edition, Ed. By F.M. Bourland, J. O. Ware Dec 2023

Origin, Rise And Development Of American Upland Cotton And Their Status At Present. Second Edition, Ed. By F.M. Bourland, J. O. Ware

Research Reports and Research Bulletins

American Upland cotton (Gossypium hirsutum) is a Dixie product. Although the stocks of the species were brought from elsewhere, new types (through series of adaptational changes) formed this distinctive group—the final characteristics of which are a product of the Cotton Belt of the United States. These biological processes were considerably aided by man and the steps of development possibly were about as follows: (a) natural selection took place in the earlier introductions, (b) seed were saved from the more choice stocks, (c) series of subsequent introductions were obtained from the better sources, (d) these were acclimatized and the superior ones …

Screening And Selection For Resistance To Gray Leaf Spot (Pyricularia Oryzae) In Early Planted Annual Ryegrass, Calyn M. Adams Aug 2023

Screening And Selection For Resistance To Gray Leaf Spot (Pyricularia Oryzae) In Early Planted Annual Ryegrass, Calyn M. Adams

Theses and Dissertations

Cattlemen in the southeastern United States widely plant annual ryegrass [Lolium perenne L. spp. multiflorum (Lam.) Husnot] (ARG). It is often planted earlier than the recommended window. This exposes juvenile stands to increased pressure from gray leaf spot (Pyricularia oryzae Cavara) (GLS), causing stand loss. This study was designed to screen for resistance to P. oryzae in two ARG genotypes, Vertyl and a heat-tolerant germplasm (HTARG5) with the objective of developing a crossbred population to be improved using restricted, recurrent phenotypic selection. Experiments were conducted from 2021 – 2022. Disease severity (DS) was assessed 3wk after inoculation with …

Genetic Resources And Precise Gene Editing For Targeted Improvement Of Barley Abiotic Stress Tolerance, Sakura Karunarathne, Esther Walker, Darshan Sharma, Chengdao Li, Yong Han

Grain and Other Field Crops Research Articles

Abiotic stresses, predominately drought, heat, salinity, cold, and waterlogging, adversely affect cereal crops. They limit barley production worldwide and cause huge economic losses. In barley, functional genes under various stresses have been identified over the years and genetic improvement to stress tolerance has taken a new turn with the introduction of modern gene-editing platforms. In particular, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) is a robust and versatile tool for precise mutation creation and trait improvement. In this review, we highlight the stress-affected regions and the corresponding economic losses among the main barley producers. We collate about …

Pricing Stallion Seasons For An Individual Stallion: The Existence Of Top Tier Pricing And Market Power, Robert L. Losey Ph.D., Thomas E. Lambert 1959- Apr 2020

Pricing Stallion Seasons For An Individual Stallion: The Existence Of Top Tier Pricing And Market Power, Robert L. Losey Ph.D., Thomas E. Lambert 1959-

Faculty Scholarship

This paper is an academic treatment of the pricing of stallion seasons (a “season” confers the right to breed a mare to a stallion) The commercial stallion seasons market can be represented schematically as a triangle that normally has a single-digit number of stallions offering high-priced seasons in the narrow apex, a moderate number of stallions composing the middle section, and over 150 in the $5,000-$10,000 range. We argue that it is logical for profit-maximizing stallion managers, most especially those in the apex of the stallion seasons triangle, to charge different prices for different groups of buyers of the same …
