Early Detection of Phoma Lingam Infection in Oilseed Winter Rape Before Visible Symptoms Appear

in vitro evaluation of oilseed rape genotypes against blackleg disease caused by phoma lingam

blackleg disease of oilseed rape, caused by leptosphaeria maculans, is one of the three most important diseases of the plant in iran. it is also considered as one of the most important diseases of oilseed rape worldwide which causes serious yield losses. during 2010 the oilseed rape fields were surveyed at province golestan and plant samples demonstrating suspected symptoms of the disease were ...

Oilseed rape and seasonal symptoms: epidemiological and environmental studies.

BACKGROUND There is widespread concern that the cultivation of oilseed rape leads to seasonal epidemics of respiratory symptoms in populations living in the neighbourhood, and it has been suggested that the plant is a potent allergen. A study was therefore undertaken to determine the prevalence of seasonal symptoms in rural populations close to and far from areas of oilseed rape cultivation, an...

The Use of Herbicides in Biotech Oilseed Rape Cultivation and in Generation of Transgenic Homozygous Plants of Winter Oilseed Rape (Brassica napus L.)

Effects of Leptosphaeria maculans race structure and fitness cost of virulence on management of phoma stem canker in oilseed rape

Fitness of virulent (avrLm1 and avrLm4) or avirulent (AvrLm1 and AvrLm4) isolates of Leptosphaeria maculans on Brassica napus without the corresponding resistance genes Rlm1 and Rlm4 was investigated in controlled environment (CE) and field experiments. Results indicate that there is a measurable fitness cost for virulent isolates compared to avirulent isolates in terms of number of lesions, si...

Assessing Quantitative Resistance against Leptosphaeria maculans (Phoma Stem Canker) in Brassica napus (Oilseed Rape) in Young Plants

Quantitative resistance against Leptosphaeria maculans in Brassica napus is difficult to assess in young plants due to the long period of symptomless growth of the pathogen from the appearance of leaf lesions to the appearance of canker symptoms on the stem. By using doubled haploid (DH) lines A30 (susceptible) and C119 (with quantitative resistance), quantitative resistance against L. maculans...
