Management Approaches

White rust distributed worldwide, caused by Albugo candida (Pers. Ex. Lev.) Kuntze. (A. Cruciferarum S. F. Gray) is one of the major disease responsible in reducing the yield of rapeseed-mustard. Among various management approaches use of resistant varities is consider best, as it is cost effective and environment friendly. However, till now only few resistant sources against the disease has been reported. Therefore, in the present investigation 70 rapeseed-mustard germplasm have been evaluated in field under epiphytotic conditions during 2011-12 and 2012-13 crop seasons. All the germplasms showed similar disease reaction after screening in both the years. Among 70 germplasm, seven germpalsms i.e. DLDC-1, DRMR-100, DRMR-312, EC-339000, GSL-1, NPJ-158 and RH-0644 were found free from the disease with 0% disease severity. These germplasms could be used in breeding programmes for the development of resistant genotypes having high yield potential.

Major Threat

Brassica napus (Rapeseed) affected by white rust is a major threat in Pakistan causing 60-90% yield losses. Two susceptible varieties of Brassica napus DGL and Oscar were sown in research area of department of Plant Pathology during 2016-17. Eight commercial fungicides were applied to check their efficacy to manage the white rust disease. Two concentrations (0.25% and 0.50%) of each fungicide were applied on weekly interval with hand sprayer separately on each variety. It was concluded that among all fungicides, Swing 72% (Metalaxyl 8% +Mancozeb 64%) was found most effective in reducing the disease incidence. It reduced the disease incidence effectively upto 24.09% followed by Antracol (Propineb 70%) 34.7%.

Race 2

White rust and staghead, caused by Albugo candida, is an economically important disease of Brassica juncea and Brassica rapa crops in western Canada. The identification of genes for white rust resistance in these crops and the development of molecular markers for these genes will allow the rapid identification of resistant germplasm and should accelerate the development of white rust resistant cultivars. In this study, 119 F1-derived doubled-haploid progeny lines of a cross between white rust susceptible (J90-4317) and white rust resistant (J90-2733) B. juncea lines were evaluated for resistance to A. candida race 2. A single gene (Acr) responsible for conferring resistance to this pathogen was mapped on a densely populated B. juncea RFLP map developed earlier. A cosegregating RFLP marker (X140a) and two other closely linked RFLP markers (X42 and X83) were identified; the latter two markers were 2.3 and 4 cM from the Acr locus, respectively. These markers may be useful for marker-assisted selection and map-based cloning of this gene.Key words: Brassica juncea, mustard, Albugo candida, white rust, disease resistance, RFLP.

The obligate plant parasite fungi in the family Albuginaceae are responsible for causing white rust diseases on weeds and they are rather common worldwide. Weedy plants with characteristic symptoms have been collected in 2014 and 2015 on location Hajdú-Bihar and Jász-Nagykun-Szolnok counties in Hungary. The determination of the species were based on the morphological characters both pathogens and hosts. Albugo candida was determined on shepherd’s purse (Capsella bursa-pastoris). Common purslane (Portulaca oleracea) is a host for Wilsoniana portulacae. The fungus Wilsonia bliti (syn.: Albugo bliti), the causal agent of white rust disease was found on redroot pigweed (Amaranthus retroflexus).

Insight Into

: Oilseed brassicas stand as the second most valuable source of vegetable oil and the third most traded one across the globe. However, the yield can be severely affected by infections caused by phytopathogens. White rust is a major oomycete disease of oilseed brassicas resulting in up to 60% yield loss globally. So far, success in the development of oomycete resistant Brassicas through conventional breeding has been limited. Hence, there is an imperative need to blend conventional and frontier biotechnological means to breed for improved crop protection and yield. : This review provides a deep insight into the white rust disease and explains the oomycete-plant molecular events with special reference to Albugo candida describing the role of effector molecules, A. candida secretome, and disease response mechanism along with nucleotide-binding leucine-rich repeat receptor (NLR) signaling. Based on these facts, we further discussed the recent progress and future scopes of genomic approaches to transfer white rust resistance in the susceptible varieties of oilseed brassicas, while elucidating the role of resistance and susceptibility genes. Novel genomic technologies have been widely used in crop sustainability by deploying resistance in the host. Enrichment of NLR repertoire, over-expression of R genes, silencing of avirulent and disease susceptibility genes through RNA interference and CRSPR-Cas are technologies which have been successfully applied against pathogen-resistance mechanism. The article provides new insight into Albugo and Brassica genomics which could be useful for producing high yielding and WR resistant oilseed cultivars across the globe.
