Perennial cereal rye (Secale cereale L. × Secale montanum Guss.) has been utilized for forage production and this study investigated its perennial grain production potential in Manitoba. Two seeding years at Carman, MB, showed poor winter survival and high ergot occurrence. Therefore, this species is not recommended for grain production in Manitoba.

Perennial cereal rye (PC rye) is being developed at Lethbridge Research Centre as a new forage crop. The first Canadian cultivar of this crop (ACE-1), tested as LRC 96-1, will have the distinction of being the first North American cultivar of PC rye and the only perennial cereal crop specifically developed for forage production. PC rye was originally developed in Germany by crossing rye (Secale cereale L.) with a perennial wild rye (Secale montanum L.) and then backcrossing the F1 with Secale cereale L. while selecting for a perennial nature. In field trials, ACE-1 PC rye has produced economically viable biomass yields for 3 yr under southern Alberta growing conditions. It has similar yield and quality to barley, which is grown extensively for silage in the Canadian prairies. For proper land management and adequate forage production, ACE-1 PC rye should be seeded from mid-September to mid-October in narrow (17.5 cm) rows at a seeding rate of 80 kg ha-1. When harvested at the soft dough stage for silage it contained less crude protein (CP) and more fibre than barley; however, in vitro gas production indicates that its dry matter (DM) digestibility will be similar to that of barley. PC rye is a valuable forage crop, but it needs to be harvested earlier than the soft dough stage to obtain comparable silage quality to barley.

Breeder Seed

Danko is a winter rye (Secale cereale L.) cultivar with higher yield, better lodging resistance and winter survival and higher kernel weight and test weight than Animo and Kustro, the current most commonly grown cultivars in the Maritimes. It was developed at the Polish Plant Breeding Institute, Poznan, Poland where breeder seed will be maintained. Seed will be distributed by King Grain Ltd.Key words: Secale cereale L., rye (winter), cultivar description

Non-irrigated corn (Zea mays L.) produced on coarse-textured soils during droughty years can result in excess NO3 available for leaching. To evaluate the effect of overseeding cereal rye (Secale cereale L.) into corn on yields, NO3 leaching and a pre-sidedress nitrate test (PSNT), we broadcast rye seed (Aug. 1993, 1994 and 1995) into conventional tillage (CT) and no-tillage (NT) corn receiving six fertilizer N rates. There was no corn yield penalty with the cover crop. Corn grain yields and the extent to which NO3 leaching was reduced by the rye cover depended on rainfall. With the rye (compared with no rye) subsoil solution NO3 concentrations were: unchanged (fall 1994) following above normal rainfall and corn yields; reduced by 8 mg NO3N L−1 (fall 1995) following intermediate rainfall and yields; and reduced by 28 mg NO3-N L−1 (fall 1993) and 11 mg NO3-N L−1 (spring 1994) following the driest growing season (average of CT and NT). Improved N availability with the rye was detected by a PSNT under CT, but not under NT. Therefore sidedress N rates can be adjusted for release of rye residue-N under CT, and potential NO3 contamination of groundwater can be reduced by overseeding winter rye into both CT and NT corn systems.

The effects of fall, spring, and spring plus fall defoliation were studied in four winter rye (Secale cereale L.) cultivars for 2 yr. On average, the three treatments reduced grain yield by 8.7%, 16.6% and 23.2%, respectively, compared to the untreated check. The four cultivars responded similarly.Key words: Secale cereale L., rye (fall), simulated grazing, defoliation, cereals (winter)

SUMMARYThe genetic structure of six rye (Secale cereale L.) cultivars bred as forage cultivars was investigated by means of nine isozyme loci. The isozyme systemselectrophoretically studied were glutamic oxaloacetic transaminase; phosphoglucose mutase; phosphoglucose isomerase; acid phosphatase; malic dehydrogenase and 6-phosphogluconate dehydrogenase. Alleles present and their frequencies were very similar in all cultivars; thus genetic distances between cultivars ranged from 0·000 to 0·005. Likewise, a general excess of homozygotic plants compared with the expected number was observed in cultivars. The genetic structure of these populations is closely similar to other rye cultivars, bred for grain production, which were previously analysed.

Rain Events

To assess the risk that liquid swine manure (LSM) application posed to groundwater quality and determine how to manage excess nitrates, LSM pre-plant injected at 75% (LSMlow) and >100% (LSMhigh) of corn (Zea mays L.) N requirements was compared to inorganic fertilizer (Fert), with (RC) or without (NC) a rye (Secale cereale L.) cover crop in 2 dry years (1999, 2001) and 1 wet year (2000) on sandy soil in Ontario. Corn yields in LSM and Fert treatments were comparable each year. When drainage potential was high, solution nitrates below the root zone in Fert (14 mg L-1) > LSM (7 mg L-1) in 1999, but in LSM (39 mg L-1) > Fert (13 mg L-1) in 2000. Occasionally in 2001, solution nitrates in LSMhigh > LSMlow and/or Fert plots, but drainage potential was low. Earlier N application in LSM (pre-plant) than Fert (77% of N sidedressed) plots in relation to rain events may have increased solution nitrates in LSM plots in 2000. Rye cover reduced solution nitrates from 8.8 mg L-1 (NC) to 4.3 mg L-1 (RC, average of all dates), regardless of nutrient source. In-season risk of NO3 leaching can be reduced by split application of N between pre-plant and sidedress, while overseeding cereal rye into standing corn minimizes leaching post-harvest (fall and spring).
