Athena Rape - 50 lbs.
Athena is a near-homozygous winter rapeseed cultivar with canola-quality seed oil and canola-quality seed meal, selected for its high adaptability to dryland and irrigated regions of the inland Pacific Northwest.
Athena was evaluated in field trials in Idaho, Washington, and Oregon for six growing seasons from 1996 to 1997 through 2001 to 2002. Evaluation trials conducted during the 1998 to 1999 through 2001 to 2002 seasons were part of the Pacific Northwest Winter Canola Variety Trials (Brown et al., 1999; 2000; 2001; 2002). Performance was compared to four commercially available cultivars: Ericka, Ceres, Cascade, and Olsen. The cultivars Ericka (Brown et al., 1997), Cascade (Auld et al., 1987), Ceres, and Olsen [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, Athena 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 Athena flowers significantly later, averaging DOY 131. The flowering date of Athena is not significantly different from Ceres or Olsen. Plant height of Athena is 144 cm, significantly taller than Ericka, but not significantly different from Ceres or Olsen. Despite producing tall plants, Athena is resistant to lodging and was found to be significantly less likely to lodge compared to Olsen. Athena plant maturity is intermediate, being significantly later than either Ericka or Cascade, but not significantly different from Olsen or Ceres. Athena 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, Athena produced significantly higher seed yield (3332 kg ha−1) than any check cultivar. Athena was highly adapted to later planting and direct seeding into cereal stubble. The yield advantage of Athena was particularly noted under these conditions. Athena was the highest yielding entry in five of the six years tested and was second highest in the other year.
Athena Rape Seed is planted at a rate of 5 to 10 lbs per acre.
