Details for: PI 633734, Brassica napus L. subsp. napus, 'ATHENA'

Winter rapeseed with canola-quality seed oil and canola-quality seed meal. High adaptability to the Pacific Northwest Region (Idaho, Washington and Oregon). Seedlings emerge quickly after seeding and produce a good fall stand compared to other control cvs. This is particularly true when planted late in the fall or when re-cropped by seeding into straw stubble. Flowers significantly later, on average 131 days, than Ericka, which on average flowered after 128 days. Flowering date is not significantly different from Ceres or Olsen. Plant height 144 cm, is significantly taller than Ericka and not significantly different from Ceres or Olsen. Lodge resistant and was found to be significantly less likely to lodge compared to Olsen, despite tall plant heights. Plant maturity intermediate, being significantly later than either Ericka or Cascade, but not significantly different from the other control cvs. Determinate growth habit and plants dry down evenly at maturity, an advantage to growers because this can help avoid seedpod shatter and ease harvest. Average oil content significantly greater than Ericka and Ceres, in 1999, but not significantly different from the control cvs. in the other years. Oil quality high with less than 10 g kg-1 erucic acid and less than 85 g kg-1 linolenic acid. The remaining fatty acid profile was not significantly different from the high quality cvs. Cascade and Ericka. Seed meal glucosinolates were moderate to low (25 umol g-100).
