Blackleg disease caused by the heterothallic ascomycete fungus Leptosphaeria maculans (Desm.) Ces. et de Not. (anamorph: Phoma lingam Tode ex Fr.), is the major disease of Brassica crops such as turnip rape (Brassica rapa L. syn. B. campestris; 2n = 2x = 20, genome AA), cabbage (B. oleracea L.; 2n = 2x = 18, genome CC), rapeseed (syn. canola or oilseed rape B. napus L.; 2n = 4x = 38, genome AAC...

Brassica crops have indeterminate growth and flower over an extended period of time. Harvested seed is therefore comprised of seed of varying degrees of physiological maturity and quality. Using population-based threshold models, broccoli (Brassica oleracea L. Group Italica), brussels sprouts (B. oleracea L. Group Gemmifera), red cabbage (B. oleracea L. Group Capitata), and rapeseed (B. napus L...

designing breeding programs for winter rapeseed (brassica napus l.) cultivars with improved seed and oil yields requires information about the genetic variability of traits. in this study, 28 winter rapeseed cultivars were evaluated for genetic variation and relationships between 11 agro-morphological characters during 2010 and 2011. cultivars and cultivar × year interaction showed significant ...

Canola is an offspring of rapeseed (Brassica napus and Brassica campestris/rapa), which was bred through standard plant breeding techniques to have low levels of erucic acid and glucosinolates. Canola seed is rich in oil, and after oil extraction, the remaining “canola meal” (CM), is a rich protein source used as feedstock to different animal species, mainly dairy cows in North America and in E...

The micromorphological typology of seed surfaces was investigated in rapid-cycling Brassica (RCBr) forms, using scanning electron microscopy. Four types of basic ornamentation pattern were recognized: reticulate (B. rapa, B. juncea), reticulate-foveolate (B. nigra), randomly reticulate (B. oleracea, B. napus) and reticulate-rugose (B. carinata). The seed coats showed variation in the shape and ...

background: lead and cadmium are toxic heavy metals found as major contaminants in food products and edible oils. the aims of this study were to investigate the lead and cadmium contaminations in seeds and extracted oils from brassica napus l and carthamus tinctorius grown in the vicinity of industrial sites (isfahan zobe ahan) near isfahan province/iran. methods: in this study, the seeds of b....

A stable yellow-seeded variety is the breeding goal for obtaining the ideal rapeseed (Brassica napus L.) plant, and the amount of acid detergent lignin (ADL) in the seeds and the hull content (HC) are often used as yellow-seeded rapeseed screening indices. In this study, a genome-wide association analysis of 520 accessions was performed using the Q + K model with a total of 31,839 single-nucleo...
