In India, oilseed Brassica are grown over an area of about 6.3 million hectares with an annual production of 7.92 million tones with an average yield of 1304 kg/ha whereas in Rajasthan it was still 1422kg/ha. The severe attack of many diseases not only deteriorates the quality of the seed, but also reduces the oil content considerably. Among the diseases, white rust caused by Albugo candida (Pers. Ex Hook) O. Kuntze, is an important disease of a wide variety of Brassica crops. Its infection causes disfiguring white pustules on leaves, flowers stems and pod leading to yield losses.

In this series observation were also made on impact of disease on growth and development of a plant internally and externally. Small creamy white spot on cotyledons can be seen. Downy growth of fungus appears on leaves, stem and on stage heads formed by white rust pathogen, Albugo candida. Mixed infection of white rust and downy mildew is common on stage heads.

White rust caused by a fungus Albugo candida, is a destructive disease of many economically important species of Brassica, to control this resistance breeding is important .Marker validation is useful for testing reported markers in determining the target phenotypes in autonomous populations and dissimilar genetic backgrounds and also involves testing the reliability of marker to predict the phenotype, which defines whether or not a marker could be used in routine screening for MAS.

Indian mustard (Brassica juncea) is the most important and major edible oil seed crop. White rust [Albugo candida (Pers. Ex.Lev.) Kuntze] is the important disease which can cause major yield losses in Indian Mustard. This study shows comparative assessment of white rust disease index (%), white rust disease severity and white rust disease incidence on leaves as well as on the inflorescence in the improved varieties of Indian Mustard.

Albugo candida causing white rust of rapeseed-mustard is a highly variable fungus and cause great economic losses. In this study 44 A. candida isolates belongs to 17 different states of India has been used for the pathogenicity diversity. Symptomatology of the pathogen i.e. pustule pattern, pustule size and pustule colour has taken as criteria for the pathogenicity diversity. All the 44 A. candida isolates were inoculated on susceptible Brassica juncea cultivar Varuna for the study.

Field integration of various fungicides, phytoextracts and essential oils (alone and in combination) as seed treatments and foliar sprays significantly reduced mustard white rust disease caused by Albugo candida (Pers.) Kuntze, over untreated control, along with enhanced seed and straw yields and better ICBR. Based on performance merit, the best treatments were Metalaxyl 35%SD- ST @ 6g/kg + Metalaxyl 4%+ Mancozeb 68%WP- FS @ 0.25%>Metalaxyl 4%+ Mancozeb 68%WP -FS @ 0.25% + Azadirachta indica @ 20%>Metalaxyl 4%+ Mancozeb 68%WP- FS @ 0.
