Lentil is a self-pollinated annual diploid (2n = 2× 14) crop with restricted history of genetic improvement through breeding, particularly when compared to cereal crops. This limited breeding has probably contributed the narrow base local cultivars, and corresponding potential continue yield increases stability. Therefore, knowledge variation relationships between populations important for understanding available variability its use in programs. Single nucleotide polymorphism (SNP) markers...
With 1 figure and table Abstract Potato cyst nematode (PCN) is a major pest of potato crops. Marker‐assisted selection PCN‐resistant cultivars consequently key objective many breeding programmes. The genetic marker TG689, linked to the resistance gene H1 , current choice for prediction PCN resistance. Polymorphism at TG689 was evaluated across 373 from Australian Scottish programmes, revealing loss association between predictive allele trait locus. Two recently identified markers flanking...
Lentil (Lens culinaris Medik.) is a self-pollinating, diploid, annual, cool-season, food legume crop that cultivated throughout the world. Ascochyta blight (AB), caused by lentis Vassilievsky, an economically important and widespread disease of lentil. Development cultivars with high levels durable resistance provides environmentally acceptable feasible method for AB control. A detailed understanding genetic basis hence highly desirable, in order to obtain insight into number influence...
Potato is an important food crop due to its increasing consumption, and as a result, there demand for varieties with improved production. However, the current status of breeding long process which relies heavily on phenotypic evaluation dated molecular techniques has little emphasis modern genotyping approaches. Evaluation selection before cultivar commercialized typically takes 10-15 years. Molecular markers have been developed disease pest resistance, resulting in initial marker-assisted...
Field pea (Pisum sativum L.) is an important grain legume consumed both as human food and animal feed. However, productivity in low rainfall regions can be significantly reduced by inferior soils containing high levels of boron and/or salinity. Furthermore, powdery mildew (PM) (Erysiphe pisi) disease also causes significant yield loss warmer regions. Breeding for tolerance to these abiotic biotic stresses are major aims breeding programs the application molecular markers traits could greatly...
Early vigour of seedlings is a beneficial trait field pea (Pisum sativum L.) that contributes to weed control, water use efficiency and likely contribute yield under certain environments. Although breeding considered the most effective approach improve early pea, absence robust high-throughput phenotyping tool dissect this complex currently major obstacle genetic improvement programs address issue. To develop tool, separate trials on 44 genetically diverse genotypes were conducted in...
Within the Brassicaceae, six species from genus Brassica are widely cultivated throughout world as oilseed, condiment, fodder or vegetable crops. The genetic relationships among described by U's triangle model. Extensive shared traits and diverse morphotypes make identification classification based on phenotypic data alone challenging unreliable, especially when dealing with large germplasm collections. Consequently, a major issue for genebank collections is ensuring correct of species....
Genomic prediction is becoming a popular plant breeding method to predict the genetic merit of lines. While some genomic results have been reported in canola, none evaluated for blackleg disease. Here, we report seedling emergence, survival rate, and internal infection), using 532 Spring Winter canola These lines were phenotyped two replicated disease nurseries grown at Wickliffe Green Lake, Victoria, Australia. A transcriptome genotyping-by-sequencing approach revealed 98,054 single...
High-throughput phenotyping is a rapidly evolving field, with new technologies being developed that need to be tested under different experimental conditions. In this study, the PlantEye, high-resolution three-dimensional (3D) laser scanner was used phenotype wheat plants grown control and salt stress in controlled environment The PlantEye scans from overhead, creating data cloud which system computes traits such as 3D leaf area, plant height number. Moderately high correlations were...
Potatoes are an important human food crop, but have a number of yield limiting factors, including disease susceptibility. Potato virus Y (PVY) is found worldwide, and one the main problems for potato growers. PVY transmitted by aphids mechanically machinery, tools people, symptoms variable across cultivars strains, being symptomless in some cultivars. Therefore, breeding resistant best way to control this virus. This study phenotypically screened 74 commercial few other select grown...
Abstract Using genomic information to predict phenotypes can improve the accuracy of estimated breeding values and potentially increase genetic gain over conventional breeding. In this study, we investigated prediction accuracies achieved by best linear unbiased (BLUP) for nine potato phenotypic traits using three types relationship matrices pedigree ABLUP, GBLUP, a hybrid matrix ( H ) combining (HBLUP). Deep was available >3000 different clones evaluated four years. Genomic relationships...
Two stilbenes, resveratrol and pterostilbene, exhibit antifungal activity against Leptosphaeria maculans, the fungal pathogen responsible for blackleg (stem canker) in canola (Brassica napus). In vitro studies on effect of these stilbenes L. maculans mycelial growth conidia germination showed that pterostilbene is a potent fungicide sporicide, but only exerted minor inhibition maculans. Cell viability hyphae cultures was markedly reduced by SYTOX green staining cell membrane integrity...
Field phenotyping to identify water stress‐tolerant crop genotypes is challenging due uncertainty in the timing of rainfall. Rainout shelters offer a way establishing controlled stress environments by excluding untimely rain events. Here, we present detailed description custom‐designed rainout shelters. These are fully automated and portable. The were constructed from steel arch frames polyethylene cladding, which move on plastic road barriers. three connected shelters, each 20 × 10 m,...
Potato is an important food crop worldwide and grown in a large number of countries. As such, the under disease pressures need for selecting resistance genes during breeding programs essential. Of particular importance within Australia other parts world potyvirus, virus Y (PVY). In this paper, three commonly used PVY markers, M45, RYSC3 M6, were evaluated using existing genomic resources phenotypic data from Australian potato program to identify region where gene, Ryadg may reside.
