Three studies in marker-assisted plant breeding
Effective breeding for crop improvement has the potential to increase food security, improve environmental health, and contribute to economic development. Here, we present three studies which further our understanding of marker-assisted plant breeding and plant genetics. First, we fine-map a …

Learning from data: Plant breeding applications of machine learning
… new sources of data are being incorporated into plant breeding pipelines. Enormous amounts of data from field phenomics and genotyping technologies places data mining and analysis into a completely different level that is challenging from practical and theoretical standpoints. Intelligent …

Models and methods for computer simulations as a resource in plant breeding
A number of crucial decisions face the plant breeder in developing improved cultivars. Because of the impact and modern complexity of these decisions, computer simulation based on effective models can be an important resource for the breeder, particularly in providing guidance on choice of parents …

High-Throughput Phenotyping and Genomic Prediction in Multi-Environment Plant Breeding Field Trials
Plant breeding requires phenotyping for multiple traits throughout the growing season in large, multilocation field trials. This large-scale phenotyping produces the data necessary to select lines with a desirable combination of traits. The use of unoccupied aerial vehicles (UAVs) equipped with …

Statistical methods and models for analyzing sugarcane (Saccharum species hybrids) plant breeding data
… LRM can be used to identify important traits in breeding populations as well as directionally shifting population trait values during selection. Neural network models can be used to automate the LRM. The multivariate repeated measures analysis (MRM) reduced Type I errors associated with …

FUNCTIONAL CHARACTERIZATION OF VPS13 DURING SEXUAL AND APOMICTIC PLANT REPRODUCTION: THE MISSING GENE FOR PLANT BREEDING?
… la potenzialità di cambiare il mondo del breeding. Uno dei geni candidati per il controllo dell’apomissia in pianta è VPS13, che è stato identificato in tarassaco. Durante il mio progetto di dottorato, ho investigato il possibile ruolo di VPS13 nello sviluppo riproduttivo di due specie, …

The Ecology of Sexual and Apomictic Reproduction in Antennaria Parlinii Gaertner (Apomixis, Plant Breeding Systems, Evolution)
… parlinii, in which seed production occurs in plants that are either sexual and dioecious or apomictic. Studies of seedlings and ramet production by adult plants in natural populations documented differences in survivorship and allocation between sexual and apomictic plants. Populations of …

Ärftlighetsforskningens gränser : Individer och institutioner i framväxten av svensk genetik
… Mendelism was introduced as a methodology in plant breeding at the plant breeding station in Svalöf during the first decade of the 20th century by Herman Nilsson-Ehle. He was given a personal professorship in genetics at Lund University in 1917, mainly due to his success in improving some …

Statistical genetics tools for empowered data-driven decisions
The pressure to accelerate results in plant breeding programs is intensifying. Conversely, there is a concerning decline in the genetic diversity of staple crops, making it increasingly difficult to achieve genetic gains. Consequently, efficient resource allocation within breeding programs requires the …

Evaluation of Subirrigation, With Respect to Soil Water Flow Behavior and Effects on Plant Growth
With recent improvement in plant breeding, fertility management, weed control and cultural practices, water management is becoming the limiting factor, even in the humid midwest, for increased production and improved quality of crops. There has been an increased interest in application of …

Simultaneous Mapping and Pyramiding of Fusarium Head Blight Resistance Loci in Wheat Breeding Populations
<p>QTL linkage analysis for plants has relied on large single-cross mapping populations derived from phenotypically divergent parent lines. This approach creates a disjunction between QTL mapping and marker-assisted breeding efforts aimed at pyramiding QTL, since no direct bridge exists between the …

The effect of temperature stress on recombination in barley
Plant breeding is ultimately dependent on the process of recombination which is responsible for the generation of different genotypes with new allelic combinations. The control of meiotic recombination is increasingly being considered as a possible means of aiding plant breeding to tackle the …

Novel strategies for genomic and phenomic investigations of quantitative traits in maize (Zea mays L.)
… they promise to increase the efficiency of plant breeding solutions. Root system architecture (RSA) plays important roles the adaptation of crops to the environments in which they are grown, but the genetic basis of RSA traits is understudied due to the difficulty of phenotyping for RSA …

The Role of Carotenoid Cleavage Dioxygenase 4 in Flower Color of the Allopolyploid Brassica napus
… the context of molecular biology, evolution, and plant breeding, plant biologists study the model organism <em>Brassica napus</em> (farmed as canola or oilseed rape). With white-flowering and yellow-flowering progenitors, flower color phenotype of <em>B. napus </em>presents an opportunity to …
