BackgroundMustard aphid is a major pest of Brassica oilseeds. No source for aphid resistance is presently available in Brassica juncea . A wild crucifer, Brassica fruticulosa is known to be resistant to mustard aphid. An artificially synthesized amphiploid, AD-4 (B. fruticulosa × B. rapa var. brown sarson) was developed for use as a bridge species to transfer fruticulosa resistance to B. juncea. Using the selfed backcross we could select a large number of lines with resistance to mustard aphid… 
Antixenosis and antibiosis mechanisms of resistance to turnip aphid, Lipaphis erysimi (Kaltenbach) in Brassica juncea-fruticulosa introgression lines
Introgression lines developed using Brassica fruticulosa found to be resistant to L. erysimi may be attributed to a synergistic combination of antixenosis and antibiosis mechanisms.
Biochemical changes in the Brassica juncea-fruticulosa introgression lines after Lipaphis erysimi (Kaltenbach) infestation
A general trend of decline in flavonols, total sugars and free amino acids content was observed after aphid infestation in all the genotypes, and there was downregulation of glucosinolates and upregulation of total phenols as against opposite trend observed in BSH-1 and PBR-210.
Some Cytomorphological Evidence for Synthesis of Interspecific Hybrids between Brassica juncea and Autotetraploid B. fruticulosa
The study suggests that B. fruticulosa has partial genome homeology with B. juncea which could be exploited in crop improvement programmes, particularly breeding for biotic stress especially, tolerance/resistance to the mustard aphid.
Substituting nuclear genome of Brassica juncea (L.) Czern & Coss. In cytoplasmic background of Brassica fruticulosa results in cytoplasmic male sterility
This newly developed CMS-fertility-restorer system has a significant potential for hybrid seed production programs in mustard as an alternative to currently popular ogura CMS system.
Reliable screening technique for evaluation of wild crucifers against mustard aphid Lipaphis erysimi (Kalt.).
Wild crucifers, including Brassica fruticulosa, B. spinescens, Camelina sativa, Crambe abysinnica and Lepidium sativum were resistant to mustard aphid L. erysimi with aphid infestation index (AII) ≤ 1 and Capsella bursa-pastoris was highly susceptible to bean aphid, Aphis fabae during its vegetative stage.
Anchoring alien chromosome segment substitutions bearing gene(s) for resistance to mustard aphid in Brassica juncea-B. fruticulosa introgression lines and their possible disruption through gamma irradiation.
The patterns of donor chromatin segment substitutions in the introgression lines (ILs) through genomic in situ hybridization (GISH) coupled with B. fruticulosa chromosome-specific oligonucleotide probes were investigated to aid the development of markers to track introgressed DNA and allow application in plant breeding.
Relative Abundance of Turnip Aphid and the Associated Natural Enemies on Oilseed Brassica Genotypes
There is a need to conserve the resident natural enemies in mustard ecosystem for effective early season suppression of the aphids population or release them early in the season to suppress aphid population in lag phase of its development.
Population dynamics of potential bioagents of mustard aphid, Lipaphiserysimi(Kaltenbach) on different cultivars of rapeseed-mustard
By computing population trends of both natu-ral enemies and aphids with meterological records would generate information on relative abundance and would certainly help in formulating sound pest management strategies against mustard aphid.
Outstanding host resistance will resolve the threat from white leaf spot disease (Pseudocercosporella capsellae) to oilseed and vegetable Brassica spp.crops
Field host resistance against the white leaf spot pathogen Pseudocercosporella capsellae was determined across one hundred and seventeen Brassica napus, with commercial cultivars Oscar and Stubby considered to be highly resistant.
Phenotypic evaluation and molecular profiling of Brassica juncea (L.) lines carrying introgressions from Erucastrum abyssinicum
Introgression lines (ILs), created in Brassica juncea, following hybridization with Erucastrum abyssinicum were studied to catalogue their genetic diversity and crop performance under stressed ecologies and Morphological evaluation helped to identify useful ILs for earliness and components associated with crop productivity.


Screening of wild crucifers for resistance to mustard aphid, Lipaphis erysimi (Kaltenbach) and attempt at introgression of resistance gene(s) from Brassica fruticulosa to Brassica juncea
The biochemical analysis suggested the possibility of high concentration of lectins to be associated with low aphid infestation in B. fruticulosa and AD-4 after 30 days of aphid release while 80% mortality was observed on BSH-1.
Genetic control of resistance to the aphid Brevicoryne brassicae in the wild species Brassica fruticulosa
Data collected from an experiment determining the resistant phenotype of lines including the selfed progenies and the F, and F 2 progeny of a cross between resistant and susceptible individual plants indicated that the resistance was not controlled by a single gene.
Variation in resistance to the cabbage aphid ( Brevicoryne brassicae) between and within wild and cultivated Brassica species
Seven Brassica species were evaluated for their resistance to the cabbage aphid, Brevicoryne brassicae, in a series of field experiments, with some plants of each accession being highly resistant and others very susceptible.
Resistance to cabbage aphid (Brevicoryne brassicae) in six brassica accessions in New Zealand
Under caged conditions in the glasshouse accessions of Brassica fruticulosa Cyrillo and B. spinescens Pomel were shown to have high levels of antibiosis resistance to all three aphid populations expressed in terms of low production of young, and in the field, very few aphids settled on the plants of these two Brassica species demonstratinghigh levels of antixenosis (non‐preference) resistance.
Resistance to the cabbage root fly, Delia radicum, within Brassica fruticulosa
Brassica fruticulosa was evaluated for resistance toward the cabbage root fly Delia radicum in comparison with a widely cultivated cauliflower cultivar and a rapid cycling Brassicaoleracea line to discuss the possible transfer of such resistance from the wild species into breeding material of cultivated types of Brassica vegetables.
Locating a resistance mechanism to the cabbage aphid in two wild Brassicas
The results suggest that the mechanism of resistance may be a mechanical blocking of the sieve element or stylets rather than a difference in the secondary plant chemistry of glucosinolates and phenolics.
Production of an interspecific hybrid between Brassica fruticulosa and B. rapa
An interspecific hybrid between a wild species and a crop Brassica species was synthesized using sequential ovary-ovule culture on MS medium supplemented with casein hydrolysate and Morphological, molecular and cytogenetic analysis confirmed the true hybrid nature of the offspring.
Transgenic Expression of Onion Leaf Lectin Gene in Indian Mustard Offers Protection against Aphid Colonization
Deployment of the appropriate lectin gene figures as crucial in the transgenic approach to protect crop plants against sapsucking insect pests is seen as crucial.

Influence of Variety on Abundance and Within-Plant Distribution of Onion Thrips (Thysanoptera: Thripidae) on Cabbage
Numbers of onion thrips, Thrips tabaci Lindeman, were significantly lower in August and early September in the heads of two resistant cabbage varieties than in two susceptible varieties (‘Market Prize’ and ‘Supergreen’).
