چکیده

in order to compare yield and agronomic characteristics of 38 new winter rapessed (brassica napus l.) cultivars along with okapi as check, a field experiment was carried out based on randomized complete block design during 2009-10 cropping season with three. rapeseed cultivars showed significant differences for all traits at 1 percent probability level. in this research, es betty, nk karibik, nk aviator, champlain and rnx 3621 cultivars showed the highest grain yield. in order to evaluate qualitative characteristics of superior rapeseed (brassica napus l.) varieties, another field experiment was performed in 2010-11 cropping season. five superior rapeseed varieties, selected of first experiment along with okapi, modena and and licord as check comprised the experimental factors. results showed that es betty variety had the highest seed yield and linolenic acid. nk aviator and champlain varieties showed superiority for linoleic acid. es betty and nk aviator had the lowest oleic acid. also, modena and champlain varieties showed the highest seed content of both iron (fe) and zinc (zn). licord had the greatest seed content of copper (cu) and manganese (mn). there was positive and significant correlation between seed yield, linolenic acid and glucosinolate content. rapeseed cultivars had significant differences for seed yield, glucosinolate content, fatty acids combination and seed content of micro nutrients elements. also, there was inverse relationship between quantitative and qualitative yield in rapeseed.

Agronomic and Seed Quality Traits Dissected by Genome-Wide Association Mapping in Brassica napus

In Brassica napus breeding, traits related to commercial success are of highest importance for plant breeders. However, such traits can only be assessed in an advanced developmental stage. Molecular markers genetically linked to such traits have the potential to accelerate the breeding process of B. napus by marker-assisted selection. Therefore, the objectives of this study were to identify (i)...

Eight winter rapeseed genotypes GA096, Geronimo, Okapi, Orient, Sunday, Zarfam, SW0756, and Modena were used as parents of a complete diallel mating design. A set of 56 diallel F1 hybrids (with reciprocals) including their parents were evaluated in a 8×8 simple lattice design with two replications during 2007/08. Several agronomic traits like Plant height, number of lateral branches per pod, nu...

Unraveling the Genetic Basis of Seed Tocopherol Content and Composition in Rapeseed (Brassica napus L.)

BACKGROUND Tocopherols are important antioxidants in vegetable oils; when present as vitamin E, tocopherols are an essential nutrient for humans and livestock. Rapeseed (Brassica napus L, AACC, 2 n = 38) is one of the most important oil crops and a major source of tocopherols. Although the tocopherol biosynthetic pathway has been well elucidated in the model photosynthetic organisms Arabidopsis...
