The leaves of 'MSL 527C' have very few lobes with a sharp margin with shallow leaf dentation whereas the leaves of 'Defender' have few lobes with an undulating margin with very shallow dentation. The flowers of 'MSL 527C are yellow with white stripes in some environments whereas the flowers of 'Defender' are yellow. The silique beak and silique pedicel of 'MSL 527C' are shorter than those of 'Defender'. The plants of 'MSL527C' are taller than the plants of 'Defender' at maturity.


PLANT: male sterile mother line, spring seasonal type, tall at maturity

LEAF: dark green, very few lobes, sharp margins with shallow dentation

FLOWERS: yellow with white stripes in some environments

SILIQUE: medium in length, short beak, very short pedicel

SEED: black

QUALITY CHARACTERISTICS: erucic acid less than 0.2% of total fatty acids, high glucosinolate content less than 30 umol/g

Origin & Breeding History: 'MSL 527C' was derived from a cross made in 1999 in Hohenlieth, Germany in conjunction with Svalöf Weibull AB, Svalöv, Sweden. Selection criteria included male sterility, earliness, straw stiffness, high oil and protein content, low glucosinolate and erucic acid content.

Tests & Trials: Tests and trials were conducted during the summers of 2003 and 2005 at Saskatoon, Saskatchewan. Plots consisted of 2 replicates of 8 rows spaced 15 cm apart, were 1.75 metres wide and 3.25 metres long. Plots were laid out in randomized complete block design.
