“…Bio-industrial farming opportunities encompass existing and emerging markets including bioenergy, biorefining and biomaterials. Conventional triticale has already been identified as a suitable resource for biofuel production (Plochl and Heiermann, 2006;Rosenberger, 2005;Rosenberger et al, 2002;Wang et al, 1997). Biotechnology may provide opportunities to improve triticale as a biofuel resource and to introduce new traits, expanding its applications with bio-industrial farming.…”

Development of transgenic triticale as a platform for novel bio-industrial products is predicated on an environmental biosafety assessment that quantifies the potential risks associated with its release. Pollen-mediated gene flow to related species and conventional triticale varieties is one pathway for transgene movement. A tier 1 quantification of triticale hybridization was conducted by emasculating and hand pollinating flowers under greenhouse conditions. Approximately 2000 manual pollinations were conducted for each cross and its reciprocal between two triticale genotypes: a modern triticale cultivar (AC Alta) and primary triticale (89TT108), and common wheat, durum wheat and rye. The frequency of outcrossing, hybrid seed appearance and weight, and F 1 emergence and fertility were recorded. Outcrossing, F 1 emergence and fertility rates were high from crosses between triticale genotypes. Outcrossing in inter-specific crosses was influenced by the species, and the genotype and gender of the triticale parent. In crosses to common and durum wheat where triticale was the male parent, outcrossing was ≥ 73.0% and ≥ 69.5%, respectively, but ≤ 23.9% and ≤ 3.0% when triticale was the female parent. Overall, outcrossing with rye was lower than with common and durum wheat. F 1 hybrid emergence was greater when triticale was the female parent. With the exception of a single seed, all wheat-triticale F 1 hybrid seeds were non-viable when triticale was the male parent in the cross. Only seven durum wheat-triticale F 1 hybrids emerged from 163 seeds sown, and all were produced with triticale 89TT108 as female parent. With rye, 8 F 1 hybrids emerged from 38 seeds sown, and all were produced from crosses to AC Alta; five with AC Alta as the female parent and three as the male. Interspecific F 1 hybrids were self-sterile, with the exception of those produced in crosses between common wheat and triticale where triticale was the female parent. Tier 2 hybridization quantification will be conducted under field conditions.

“…Triticale, a cross between wheat and rye, is another potential substrate for ethanol production, as its fermentation efficiencies are similar to those of wheat (Wang et al 1999). Compared with wheat, triticale has many desirable properties as a potential biorefinery crop, such as its ability to grow in water-deficient soils (Giunta and Motzo 2004), lower susceptibility to Fusarium culmorum (Miedaner et al 2001), and high grain yield (Rosenberger et al 2002).…”

. 2010. Effects of replacing barley grain with triticale-based dried distillers' grains with solubles on nutrient digestibility, lamb growth performance and carcass traits. Can. J. Anim. Sci. 90: 87Á98. The objective of this research was to determine the effects of increasing proportions of triticale-based dried distillers' grains with solubles (TDDGS) in the diet on nutrient digestibility, growth and carcass traits of lambs. The control diet contained 72.5% barley grain, 10.0% beet pulp, 9.0% sunflower hulls, 3.0% alfalfa meal and 5.5% mixed supplement, which contained molasses, calcium carbonate, minerals and vitamins. Treatment diets contained TDDGS in place of barley grain at 20, 40 or 60% of diet dry matter (DM). In a growth study, 60 weaned lambs stratified by live weight (26.693.6 kg) were fed one of the four diets to slaughter weight. Additionally, a digestibility study using these diets in a replicated 4 )4 Latin square design was conducted using 12 ram lambs. Increasing dietary allocation of TDDGS in the diet did not affect (P 0.12) DM intake, average daily gain or feed efficiency (feed:gain). At slaughter, cold carcass weight and grade rule scores responded quadratically (P00.04) to increasing TDDGS in the diets. Feeding TDDGS did not affect other carcass traits (P0.22). Total saturated fatty acids and monounsaturated fatty acids in subcutaneous fat were unaffected by TDDGS, whereas polyunsaturated fatty acids increased linearly (P00.03). Concentration of t10, c12-conjugated linoleic acid (CLA) in carcass fat increased linearly (P00.02) with increasing TDDGS, but there was no effect (P]0.20) on concentrations of c9, t11-CLA or t11-18:1. In the digestibility study, DM intake increased linearly (PB0.01) with increasing TDDGS in the diet, whereas digestibility of DM, crude protein and fat responded quadratically (PB0.01). Starch digestibility decreased and ADF digestibility increased linearly (PB0.01), but there was no treatment effect on NDF digestibility (P0.29). Total nitrogen, total phosphorus and soluble phosphorus excretion increased (PB0.01) with increasing TDDGS. In conclusion, TDDGS can be fed in place of barley grain at levels up to 60% in diets for lambs without adverse affects on growth performance or carcass traits, but this practice will lead to an increase in N and P excretion into the environment.Key words: Lamb, digestibility, triticale distillers grains, performance, carcass characteristics McKeown, L.
