Trophy Rape Seed

N. Deut. Pflanzenzucht (Germany)] have occupied almost the total acreage of winter canola in the region over the past 10 yr. Field trials were planted using bulked seed remaining from the Breeders Seed increase of single plant plots.   After fall seeding, Trophy seedlings emerge quickly and produce a good fall stand compared to the other check cultivars. This is particularly true when planted late in the fall directly seeding into straw stubble. On average, Ericka flowered after Day of Year (DOY) 128, while Trophy flowers significantly later, averaging DOY 131. The flowering date of Trophy is not significantly different from Ceres or Olsen. Plant height of Trophy is 144 cm, significantly taller than Ericka, but not significantly different from Ceres or Olsen. Despite producing tall plants, Trophy is resistant to lodging and was found to be significantly less likely to lodge compared to Olsen. Trophy plant maturity is intermediate, being significantly later than either Ericka or Cascade, but not significantly different from Olsen or Ceres. Trophy has a determinate growth habit with plants drying down evenly at maturity, an advantage to growers because this can help avoid seed shatter and aids in harvesting. Seeds are dark brown in color and medium to large size.   Averaged over 56 evaluation trials, Trophy produced significantly higher seed yield (3332 kg ha−1) than any check cultivar. Trophy was highly adapted to later planting and direct seeding into cereal stubble. The yield advantage of Trophy was particularly noted under these conditions. Trophy was the highest yielding entry in five of the six years tested and was second highest in the other year.
