Bacterial diseases are caused by Pseudomonas destructans, P. Insects are major pests of rape; sprayings brassica napus be planned and official recommendations followed. Fleabeetles, cutworms, red turnip beetles attack seedlings, and these, along with Diamondback moth, Beet webworm, Bertha armyworm and Imported cabbage worm, brassica napus from bud stage until maturity.

In brassica napus of reproductive structures, flowers are produced in racemes, with one raceme developing at the very top of the plant, followed by axillary racemes Lamb Flowering in Canada occurs between 45 and 70 days after seeding and lasts 14—21 days Canola Council of Canada d.


Based on typical seeding in Canada, flowering normally occurs during brassica napus months of June and July Canola Council brassica napus Canada d.

Petals drop after fertilization and a cylinder-shaped silique is formed Downey Upon maturation, this pod contains between 15 and 40 seeds. Seed pods take 35—45 days to fill Canola Council of Canada d. Of Brassica oilseed crops, B.

The seed is predominantly embryo tissue and contains less endosperm than cereal grains. The seed coat can be black or yellow and consists brassica napus an outer epidermis layer. Leaf senescence begins as the pods mature, starting with the leaves at the base of the plant Canola Council of Canada d.

Agronomic traits of this first variety included uniform early maturity, high brassica napus yield and high oil content.

Ina high-yielding B. Although yellow-seeded varieties were typically lower-yielding, they were also associated with improved brassica napus quality and therefore a high-yielding yellow-seeded canola variety became a breeding priority Rakow et al.

Seed Quality Traits Throughout the s, low erucic acid and low glucosinolate traits became high priorities for the Canadian breeding program, to produce edible oil suitable for human and animal consumption.

Since then, herbicide tolerance HT traits have been developed for four active ingredients i. Tolerance to glyphosate, glufosinate-ammonium and bromoxynil brassica napus obtained by introducing genes from other organisms into brassica napus B.
