Genetic Variability, Heritability, And Genetic Advance In Strawberry(Fragaria × Ananassa Duch.), Pranav Kumar Mishra, Ram Badan Ram, Neeraj Kumar

Turkish Journal of Agriculture and Forestry

Strawberry (Fragaria × ananassa Duch.) genotypes were evaluated to study genetic variation and the relationship between yield and its component using a randomized complete block design during 2013/14. The results showed significant variance among genotypes of all traits. The phenotypic coefficient of variation (PCV) for all the characters was slightly higher than genotypic coefficient of variation (GCV), which signified the presence of environmental influence to some degree in the phenotypic expression of characters. Dry fruit weight had the highest PCV (52.47) and GCV (48.26). The estimates of narrow sense heritability (h2) were observed to be lower than those of broad …

Single Nucleotide Polymorphism Discovery Through Illumina-Based Transcriptome Sequencing And Mapping In Lentil, Hülya Yilmaz Temel, Deni̇z Göl, Hi̇lal Betül Kaya Akkale, Abdullah Kahri̇man, Muhammed Bahatti̇n Tanyolaç

Turkish Journal of Agriculture and Forestry

Lentil, which belongs to the family Leguminosae (Fabaceae), is a diploid (2n = 2x = 14 chromosomes) self-pollinating crop with a genome size of 4063 Mbp. Because of its nutritional importance and role in the fixation of nitrogen from the atmosphere, lentil is a widely used crop species in molecular genetic studies. By using DNA markers, to date, a limited number of polymorphic bands have been generated. Therefore, it is necessary to develop additional markers to saturate the genome at high density. Single nucleotide polymorphism (SNP) markers are promising for this purpose because of their abundance, stability, and heredity; they …

What Does It Mean To Do Food Justice?, Kirsten Valentine Cadieux, Rachel Slocum

College of Liberal Arts All Faculty Scholarship

'Food justice' and 'food sovereignty' have become key words in food movement scholarship and activism. In the case of 'food justice', it seems the word is often substituted for work associated with projects typical of the alternative or local food movement. We argue that it is important for scholars and practitioners to be clear on how food justice differs from other efforts to seek an equitable food system. In the interests of ensuring accountability to socially just research and action, as well as mounting a tenable response to the 'feed the world' paradigm that often sweeps aside concerns with justice …

Evaluation Of Rhizoctonia Zeae As A Potential Biological Control Option For Fungal Root Diseases Of Sugar Beet, K M. Webb, R. M. Harveson, M S. West

Panhandle Research and Extension Center

Several common root diseases routinely damage sugar beet in Nebraska and other production areas of the Central High Plains, and it is becoming more common to find fields infested simultaneously with multiple pathogens. Owing to the shortage of available fungicides for economic management of soilborne diseases, alternative techniques such as biological control are increasingly being sought for disease management. Over the last several years, unidentified, sterile fungi have been isolated in conjunction with pathogens from infected sugar beet roots and seedlings. At least two promising isolates have been identified from in vitro assays that inhibit the radial growth of multiple …

Bacterial Wilt Of Dry-Edible Beans In The Central High Plains Of The U.S.: Past, Present, And Future, Robert M. Harveson, Howard F. Schwartz, Carlos A. Urrea, C. Dean Yonts

Panhandle Research and Extension Center

Bacterial wilt, caused by Curtobacterium flaccumfaciens pv. flaccumfaciens, was first recognized and described as a new dry bean disease near Redfield, South Dakota, after the 1921 growing season on the farm of the Office of Forage Investigations. The grower on this farm informed the federal investigators that he believed the disease to be the same one that killed 90% of his crop in 1920. For the 1921 season, he saved and planted the seed harvested from the previous year, resulting in an estimated 25% loss.

Determining Soil Texture By Feel, Edwin L. Ritchey, Joshua M. Mcgrath, David Gehring

Agriculture and Natural Resources Publications

Soil texture refers to the proportion of sand, silt, and clay in a soil. Texture influences almost every aspect of soil use, both in agricultural and engineering applications, and even how natural ecosystems function. Many scientists consider soil texture the most important soil property as it can influence soil/water relationships, gas exchange, and plant nutrition. Accurately determining soil texture in a lab requires time and money; therefore, it is often necessary to estimate soil texture in the field by feel, which can be very accurate if done correctly.
