Flax is a minor oilseed crop in Canada largely exported to the European Union for use as a source of industrial oil and feed ingredient. While flax could be genetically engineered (GE) to enhance nutritional value, the adoption of transgenic technologies threatens conventional flax market acceptability. Harvest seed loss of GE crops and the persistence of GE crop volunteers in the seed bank are major factors influencing transgene persistence. Ten commercial fields in Alberta, Canada, were sampled after harvesting conventional flax in 2006 and 2007, and flax seed density and viability were determined. Additionally, artificial seed banks were established at two locations in Alberta in 2005 and 2006 to quantify persistence of five conventional flax cultivars with variability in seed coat color (yellow or brown) and α-linolenic acid (ALA, 18:3cisΔ9,13,15) content (3 to 55%) at three soil depths (0, 3, or 10 cm). Harvest methods influenced seed loss and distribution, > 10-fold more seed was distributed beneath windrows than between them. Direct harvested fields had more uniform seed distribution but generally higher seed losses. The maximum yield loss was 44 kg ha−1or 2.3% of the estimated crop yield. Seed loss and the viability of flax seed were significantly influenced by year, presumably because weather conditions prior to harvest influenced the timing and type of harvest operations. In artificial seed bank studies, seed coat color or ALA content did not influence persistence. Flax seed viability rapidly declined in the year following burial with < 1% remaining midsummer in the year following burial but there were significant differences between years. In three of four locations, there was a trend of longer seed persistence at the deepest burial depth (10 cm). The current study predicts that seed-mediated gene flow may be a significant factor in transgene persistence and a source of adventitious presence.

Abstract The two pangasiid catfish, Pangasius bocourti and P. hypophthalmus, are widely cultured in the Mekong Delta, Vietnam. However, seed supply until recently was dependent on fry and fingerlings caught from the Mekong River. In 1994, a research programme was carried out on artificial seed production of these two species in captive conditions. In 1995, about 30,000 fingerlings were first produced in An Giang and Can Tho provinces and a proper technique of induced breeding, progressive human chorionic gonadotropin (hCG) treatment, was determined. This technique, involving two steps of hCG injections, successfully induced ovulation in 66% of 67 treated females of P. bocourti. Application of this technique to other pangasiid catfish species such as P. conchophilus, P. hypophthalmus, P. mekongensis, and P. larnaudii also resulted in breeding success. Research on larval rearing has also been conducted to improve the growth and survival of pangasiid larvae. Extension of research findings of induced breeding and larval rearing has allowed mass seed production of pangasiid catfish in the Mekong Delta.
