Brassicaceae Mustards: Traditional and Agronomic Uses in Australia and New Zealand
In vitro propagation of Ethiopian mustard Brassica carinata A Brassica carinata A. Braun is an amphi-diploid species that originated from interspecific hybridization between Brassica nigra and Brassica oleracea in the highlands of Ethiopia.
The crop has many desirable agronomic traits but with oil quality constraints like high erucic acid and glucosinolate contents.
In this study, two Braun Genotypes in Northwestern Ethiopia. Directory of Open Access Journals Sweden. Full Text Available This study was carried out with the objective to estimate the genotypic variability and other yield related traits of Ethiopian mustard in North West Ethiopia. A total of 36 genotypes of Ethiopian mustard were considered for this study. Analysis of variance was computed to contrast the variability within the collected genotypes based on yield and other yield related traits.
The results revealed highly significant values p Ethiopian mustard. Therefore, it can be concluded that the variability within Ethiopian mustard genotypes collected from different areas of northern Ethiopia is high and vital for better crop improvement.
Ethiopian mustard Brassica carinata A. Braun is an oilseed crop less known to the Commonly cultivated Brassicaceae mustards , namely garlic mustard Alliaria petiolata , white mustard Brassica alba , Ethiopian mustard B.
Genetic diversity in Ethiopian mustard Bbrassica carinata a. In this study, genetic diversity in 60 Ethiopian mustard genotypes, collected from 16 regions of Ethiopia, were assessed using the techniques of cluster and Genetic diversity analysis of mustard Brassica spp.
Molecular characterization of 16 mustard Brassica spp. A total of 40 RAPD bands were scored of which 38 Braun of East Africa. Braun is cultivated primarily for its leaves, but in Ethiopia preference is high for oil in the seed. Dual purpose importance of the seeds for planting and for oil suggests the need to improve seed production efficiency through understanding variation pattern for floral morphology and seed characters. We investigated genetic diversity and correlations for floral and seed characteristics among 14 accessions of Ethiopian mustard to improve seed set and yield.
Results were largely consistent between years, indicating that the variation measured was mainly controlled by genetic factors. High genetic variation for seed characters and reproductive phenology among the accessions was noted. The number of days to appearance of flowers showed high discriminatory ability among the accessions.
A wide continuous variation was observed among accessions for anther-stigma separation. Accessions 1, 3 and 14 were identified as early flowering.
A significant and positive correlation coefficient between short stamen height and seed weight indicated a substantial complementation among these characters for seed yield improvement. The short stamen height is a good indicator for selection in favour of seed commercialization and indices for selection of pollen parent for seed yield improvement. Accessions 5, 7, 14, 16 and 22 are best for multiple characters and are recommended for seed production for any of the seasons in Arusha, Tanzania.
Models of invasion and establishment of African Mustard Brassica tournefortii. Introduced exotic plants can drive ecosystem change. We used long-term data sets of photographs, transects for biomass of annual plants, and densities of African mustard collected at irregular intervals between and We developed predictive models for invasibility and establishment of African mustard.
Both during the initial invasion and after establishment, significant predictor variables of African mustard densities were surficial geology, proximity to the highway and axial valley ephemeral stream channel, and number of small ephemeral stream channels. The axial valley ephemeral stream channel was the most vulnerable of the variables to invasions.
Overall, African mustard rapidly colonized and quickly became established in naturally disturbed areas, such as stream channels, where geological surfaces were young and soils were weakly developed. Older geological surfaces e. Microhabitats also influenced densities of African mustard , with densities higher under shrubs than in the interspaces. As African mustard became established, the proportional biomass of native winter annual plants declined.
The objective of this research was to conduct a genetic analysis of seed tocopherols in this line. This was confirmed through a joint scaling test and additional testing of the goodness of fit of the model. Conversely, epistatic interactions were identified for total tocopherol content. Using cluster analysis based on unweighted pair-group method with arithmetic average UPGMA and principal coordinate analysis PCoA , the 21 Ethiopian inbred lines were grouped into three subgroups and the single genotype introduced from Sweden formed a separate group.
The clustering pattern failed to show a Declines in a ground-dwelling arthropod community during an invasion by Sahara mustard Brassica tournefortii in aeolian sand habitats. Heather L.
Hulton VanTassel; Anne M. Hansen; Cameron W. Barrows; Quresh Latif; Margaret W. Simon; Kurt E. Sahara Mustard Brassica tournefortii; hereafter mustard , an exotic plant species, has invaded habitats throughout the arid southwestern United States. Mustard has reached high densities across aeolian sand habitats of southwestern deserts, including five distinct sand habitats in the eastern Coachella Valley, California.
We examined trends in ground-dwelling Mercury-induced oxidative stress in Indian mustard Brassica juncea L. Mercury, a potent neurotoxin, is released to the environment in significant amounts by both natural processes and anthropogenic activities. No natural hyperaccumulator plant has been reported for mercury phytoremediation.
Few studies have been conducted on the physiological responses of Indian mustard , a higher biomass plant with faster growth rates, to mercury pollution. This study investigated the phytotoxicity of mercury to Indian mustard Brassica juncea L. Two common cultivars Florida Broadleaf and Longstanding of Indian mustard were grown hydroponically in a mercury-spiked solution. Plant uptake, antioxidative enzymes, peroxides, and lipid peroxidation under mercury stress were investigated.
Indian mustard effectively generated an enzymatic antioxidant defense system especially CAT to scavenge H 2 O 2 , resulting in lower H 2 O 2 in shoots with higher mercury concentrations. These two cultivars of Indian mustard demonstrated an efficient metabolic defense and adaptation system to mercury-induced oxidative stress.
A majority of Hg was accumulated in the roots and low translocations of Hg from roots to shoots were found in two cultivars of Indian mustard. So, it is urgent to analyze the genetic diversity and its response for the selection of short duration mustard genotypes for increasing our cropping intensity. Diversity at marker loci is currently the most feasible strategy Full Text Available There is a critical need to investigate how land application of dedicated biofuel oilseed meals affects soil ecosystems.
In this study, mustard Brassica juncea and flax Linum usitatissimum seed meals and sorghum-sudangrass Sorghum bicolor were added to soil at levels of 0, 1, 2. Nitrogen mineralization was similar for flax and mustard , except for the 2. The mustard meal greatly impacted microbial community composition, appearing to select for specific fungal populations. The potential varying impacts of different oilseed meals on soil ecosystems should be considered when developing recommendations for land application.
Breeding strategy for the improvement of mustard Brassica Juncea Coss. Mutants having desirable agronomic characters were obtained in the high yielding, recommended mustard B.
Following hybridizations between induced mutants or mutants with other promising varieties, recombinants having superior agronomic traits have been developed. The parent varieties are characterised by open pod arrangement and blackish brown seeds.
The mutants and the recombinants have desirable agronomic characters like compact plant type, appressed pods with less shattering nature, yellow seeds, higher oil content and lighter coloured oil. Among the 12 new strains developed at this centre, five have been tested at various locations in the country. At many places, TM- Trombay Mustard - cultures outyielded or were at par with the local check varieties.
Reports so far received from various locations in the country indicate that TM-strains, being relatively early cultures, are suited more for states of Rajasthan, Gujarat, U. Full Text Available Pollinators provide key services to both natural and agricultural ecosystems.
Agricultural productivity depends, in part, on pollinator populations from adjacent seminatural habitats. Here we analysed the diversity of pollinator insects and its effect to seed set of mustard Brassica rapa planted in agricultural ecosystem near the Gunung Halimun-Salak National Park, West Java. At least 19 species of insects pollinated the mustard , and three species, i. Apis cerana, Ceratina sp. The higher abundance and species richness of pollinators occurred at Insect pollinations increased the number of pods, seeds per pod, seed weights per plant, and seed germination.

Commonly cultivated Brassicaceae mustards, namely garlic mustard Alliaria petiolata , white mustard Brassica alba , Ethiopian mustard B. Mustards were naturalized to Australia and New Zealand and Australia is currently the second largest exporter of Brassicaceae oilseeds to meet the global demand for a healthy plant-derived oil, high in polyunsaturated fats. Apart from providing edible oil, various parts of these plants and many of their phytochemicals have been used traditionally for both agronomic as well as medicinal purposes, with evidence of their use by early Australian and New Zealand settlers and also the indigenous population. This review provides an overview of the current knowledge of traditional and agronomic uses of Brassicaceae oilseeds and mustards with a focus on their importance in Australia and New Zealand. Brassicaceae comprise a diverse family of plants and provide one of the most extensive and varied range of end products used by man from a single plant genus.
Michael J. Brassica carinata, sometimes called Ethiopian mustard, Abyssinian mustard, or simply carinata, is an annual oilseed crop used for the commercial production of jet fuel. Carinata by-products include seed meal for animal feed Agrisoma , and residue may act as a bio-suppressant against nematodes Oka It is similar to canola in growth habit. It is grown during the winter in the southeastern United States and shows potential as an alternative winter crop for the region. One of the challenges to commercialization of this crop in the region has been frost damage.

In central North Carolina almost any type of vegetable or fruit can be grown successfully provided you choose appropriate varieties and plant at the right time. This publication covers climate, season and potential pests that all affect the selection of what and when to plant.
This kale variety originated in the East African plain, particularly Ethiopia, as early as B. It is valuable because it will set seed at warmer tropical temperatures than other Brassicas. In East and southern Africa, young leaves are eaten as a vegetable raw or cooked. However, older varieties and particularly wild plants, have high levels of two potentially toxic compounds - erucic acid and glucosinolates - in the oil.
