Anther extrusion (AE) is the most important male floral trait for hybrid wheat seed production. AE is a complex quantitative trait that is difficult to phenotype reliably in field experiments not only due to high genotype-by-environment effects but also due to the short expression window in the field condition. In this study, we conducted a genome-wide association scan (GWAS) and explored the possibility of applying genomic prediction (GP) for AE in the CIMMYT hybrid wheat breeding program. An elite set of male lines (n = 603) were phenotype for anther count (AC) and anther visual score (VS) across three field …

Salah satu keanekaragaman tanaman pangan yang dikembangkan untuk mengurangi konsumsi beras yaitu tanaman hanjeli pulut (Coix lacryma-jobi L. var mayuen). Permasalahan yang dihadapi pada budidaya hanjeli adalah umur panen yang cukup lama dan produktivitas yang rendah. Ratun diharapkan dapat meningkatkan indeks pertanaman, namun dapat bermasalah ketika memasuki musim kemarau. Penelitian ini bertujuan untuk mempelajari perbedaan pertumbuhan, hasil, dan fenologi tanaman hanjeli pada kondisi kekurangan air. Penelitian dilaksanakan pada bulan Februari 2019 – September 2019 di Kebun Percobaan Ciparanje, Fakultas Pertanian Universitas Padjadjaran, Jatinangor. Metode analisis yang digunakan dalam penelitian ini adalah deskriptif-kuantitatif. Tanaman diberi perlakuan frekuensi penyiraman yang berbeda, yaitu …

Teh merupakan salah satu komoditas perkebunan yang memegang peranan cukup penting dalam perekonomian Indonesia, yaitu sebagai sumber pendapatan dan devisa serta penyedia lapangan kerja bagi masyarakat. Teh di Indonesia sebagian besar berasal dari Jawa Barat dengan kontribusi produksi (rata-rata lima tahun terakhir) sebesar 66,93%, sedangkan provinsi lainnya hanya berkontribusi kurang dari 10%. Produksi teh di Indonesia padatahun 2017 sebesar 146,17 ton, selalu berfluktuasi dari tahun ke tahun, hingga diperkirakan tahun 2021 menurun dengan produksi sebesar 141,63 ton. Seperti halnya komoditas perkebunan yang lain, tanaman teh dalam perkembangannya mengalami fluktuasi produksi pucuk sebagai bahan baku olahan teh. Produktivitas teh sangat dipengaruhi …

Modern plant breeding increasingly relies on genomic information to guide crop improvement. Although some genes are characterized, additional tools are needed to effectively identify and characterize genes associated with crop traits. To address this need, the mPing element from rice was modified to serve as an activation tag to induce expression of nearby genes. Embedding promoter sequences in mPing resulted in a decrease in overall transposition rate; however, this effect was negated by using a hyperactive version of mPing called mmPing20. Transgenic soybean events carrying mPing-based activation tags and the appropriate transposase expression cassettes showed evidence of transposition. Expression analysis …

Tillage Method And Glyphosate-Resistant Alfalfa Termination Timing Affect Soil Properties And Subsequent Corn Yield, Jason Clark, Matt A. Yost, Grant E. Cardon, Corey V. Ransom, J. Earl Creech
Agronomy, Horticulture and Plant Science Faculty Publications
Application of glyphosate [N-(phosphonomethyl) glycine]-containing herbicides and tillage, alone or in combination, has been the standard for removing declining alfalfa (Medicago sativa L.) stands. With glyphosate no longer an option to control glyphosate-resistant alfalfa, different termination strategies are needed. Field studies across four site-years in Utah evaluated the effect of tillage type and timing (fall conventional till, spring conventional till, fall strip-till, spring strip-till, and no-till) and herbicide timing (fall, spring, in-crop, and no herbicide) of 2,4-D (2,4- dichlorophenoxyacetic acid) and dicamba (3,6-dichloro-2-methoxybenzoic acid) on penetration resistance, alfalfa regrowth, corn (Zea mays L.) emergence rate, and silage corn yield. Across …
Parallel Strategies To Control Bacterial Panicle Blight Of Rice, Laura Ortega
Parallel Strategies To Control Bacterial Panicle Blight Of Rice, Laura Ortega
Graduate Theses and Dissertations
Bacterial Panicle Blight (BPB) of rice is a seed-borne disease caused by the bacterium Burkholderia glumae. This disease has affected rice production worldwide and its effects are likely to become more devastating with the continuous increase in global temperatures especially during the growing season. Field data has shown that the disease has been more prevalent in years when the temperatures have been unusually high especially at night possibly due to the bacterial adaptation to grow at temperatures higher than 40oC. With the continuous rise in global temperatures, it is likely that this disease will be more problematic. The bacterium can …
Resistance To Herbicides Conferred By Amaranthus Palmeri Protoporphyrinogen Ix Oxidase Mutations, Pamela Carvalho De Lima
Resistance To Herbicides Conferred By Amaranthus Palmeri Protoporphyrinogen Ix Oxidase Mutations, Pamela Carvalho De Lima
Graduate Theses and Dissertations
Palmer amaranth (Amaranthus palmeri S. Wats.) is one of the most problematic agronomic weeds to control in fields across Arkansas. Thus far, this species has evolved resistance to several herbicides, including protoporphyrinogen IX oxidase (PPO) inhibitors. The majority of PPO-resistant Palmer amaranth populations harbor a target-site mutation (substitution or deletion of amino acids). The objective of this thesis was to identify the level of fomesafen resistance conferred by PPO2 mutations from Palmer amaranth. The experiments conducted aimed to (1) characterize the level of resistance conferred by the transgene Palmer amaranth ppo2 carrying ΔG210 mutation into the wild type rice (Oryza …

Genomic selection (GS) can improve genetic gain of complex traits in plant breeding. Phenotyping agronomic traits of winter wheat (Triticum aestivum L.) for dualpurpose use is expensive and time-consuming. In this study, we compared the prediction accuracies of four GS models (RR-BLUP, GBLUP, GAUSS, and BL) for forage yield (FY), plant height (PH) and heading date (HD) of the hard winter wheat diversity panel (n = 298) using random and stratified sampling methods. In addition, we determined the appropriate training population (TP) size and marker density for GS of the traits. Moderate to high prediction accuracies ranging from 0.66 …

Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
The ability to recycle phosphorus (P) from wastewaters could provide a sustainable, continuous source of P that might also help protect surface water quality from P enrichment. The mineral struvite (MgNH4PO4·6H2O) is an understudied material that can be created from Pcontaining wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green; CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple super phosphate (TSP) on corn (Zea mays) and soybean (Glycine max) response in a 79-day greenhouse pot …
