Seed Yields

Twelve genetically diverse and geographically distinct high erucic acid rapeseed (HEAR) Brassica napus L. cultivars/lines were selected and crossed by hand emasculation in a topcross design to produce 45 F1 hybrid combinations. Seven of the twelve parents were HEAR cultivars/lines developed by the University of Manitoba (UM) and the remaining five parents were proprietary European (EU) HEAR cultivars/lines. Adequate seed was produced to evaluate the hybrids and parents in replicated yield trials in six environments in Manitoba during 2004 and 2005. Vigor, days to first flower, days to maturity, lodging, plant height, and seed yield were assessed. The hybrids were generally more vigorous, taller and more lodging resistant than their parents with similar days to first flower and days to maturity as their earlier parents. The best hybrids in this study displayed high parent heterosis for seed yield of up to 143% and commercial heterosis for seed yield of up to 99%. These hybrids were from the most genetically diverse UM × EU crosses. HEAR hybrids appear very promising approach to increase seed yields in this crop.

Doubled Haploid Breeding

Sixty families from pedigree selection and 60 lines from doubled haploid development per cross, for three different Brassica napus L. high erucic acid rapeseed (HEAR) crosses, were created and then compared for agronomic and seed quality performance in four environments in Manitoba in 2000 and 2001. Differences in mean performance for many traits were observed within crosses; however, these differences were not consistent among crosses. Similarly, there were differences observed in ranges for many traits within crosses but with few clear trends among crosses. Similar numbers of superior pedigree selection families and doubled haploid lines within and among crosses for individual traits and for combinations of all traits were found in this study. Financial and temporal resource requirements for these two breeding methods were found to be similar. It is concluded that both pedigree selection and doubled haploid breeding methods have their particular strengths and weaknesses but that neither is clearly superior for the development of B. napus HEAR cultivars.

HYHEAR 1 hybrid Roundup Ready™ high erucic acid, low glucosinolate summer rape. Can. J. Plant Sci. 94: 453–455. HYHEAR 1 summer rape (Brassica napus L.) is the world's first hybrid Roundup Ready™ high erucic acid, low glucosinolate cultivar. On average, HYHEAR 1 yielded 33% more seed, 23 g kg−1 more seed oil but 17 g kg −1 less meal protein than MillenniUM 03 high erucic acid, low glucosinolate, open pollinated population summer rape. HYHEAR 1 has an erucic acid content of 52.2% in isolated field trials of HEAR lines and is adapted to the southern B. napus growing regions of western Canada.
