Forage productivity and sequential changes in forage quality of four rye and two triticale varieties were studied. All the observed characteristics were similar among rye or triticale varieties, but they were different between rye and triticale varieties. Early growth of rye was better compared to triticale varieties, but at heading stage yield in dry weight, digestible dry matter and percent dry matter of triticale were higher compared to rye varieties. Heading stage of rye was earlier than that of triticale by 11 - 14 days. Triticale had longer and broader leaf blades and a higher leaf blade/total dry weight ratio compared to rye. Protein content decreased as plant growth advanced and it was higher in rye before heading, but it was similar after heading compared to triticale. Cellulose and lignin contents of rye increased through 20 days after heading. However, in triticale cellulose increased until heading stage and it levelled off, but lignin content increased rapidly after heading. Among the crude fibers, only acid detergent fibers(ADF) was negatively correlated with in vitro dry matter digestibility(IVDMD) in both rye and triticale. IVDMD of rye decreased rapidly after heading, but it was maintained as high as heading stage up to 15 days after heading in triticale. Protein content and IVDMD in leaf blades were higher than those of culm + leaf sheath, hemicellulose was similar, and cellulose, lignin, and ADF in leaf blades were lower compared to culm + leaf sheath. In the early and middle part of April rye was superior to triticale as a soiling crop because of a better plant growth of rye under the low temperature conditions, but in the later part of April and early part of May triticale was superior to rye because of a rapid decreased in IVDMD of rye after heading and a late maturing characteristics of triticale. Planting both rye and triticale could prolong the utilization period of the soiling crops and increase in yield with better quality compared to a single crop of rye or triticale.

Triticale(Moniko, Presto, Tewo), wheat(Kitami 66, Tsukisarnul, chihoku) and rye(Almo, Warko, Mardar) were harvested in heading, milk, dough and ripe stage. Effects of various harvesting stage on the feed chemical composition and in vitro digestibility(IVDMD) was investigated in these species and varieties. 1. Dry matter yield increased with advancing maturity regardless of forage species. Among the species triticale plants showed the highest yield. 2. The chemical composition of triticale plants in view of feed value generally placed between wheat and rye plants. 3. IVDMDs of triticale plants decreased from heading to dough stage and then increased at yellow ripe stage, while thoes of wheat and rye plants decreased with advancing maturity. Among plant species triticale. plants showed the highest IVDMD at heading and yellow ripe stage, while rye plants showed the lowest value throughout the maturity.

Three winter wheats and 3 triticales grown in Korea were compared for nutritional quality and food-making performance. The flour yield of triticale was 54 % below that of wheat, while triticale was higher in protein than wheat. The amino acid composition of triticale flours was similar to that of wheat flours. The essensial amino acid compositions were slightly higher in triticale flours. Noodles of acceptable quality were produced from triticale flours. The bread produced from triticale flours was somewhat inferior to that from soft wheat flours. The triticale flours produced bread of slightly lower quality than the soft wheat flours. The specific loaf volume were lower, the grain more rough, the texture slightly harsher and the crumb color slightly darker.

The experiment was dealt with an investigations on the agronomic potential of primary octraploid triticale in comparion with Chokwang, a major common wheat, local rye cultivar and new triticale selection Suweon #1 and Suweon #2. This octaploid triticale was originated from the cross of Jukoku #81 x Local rye cultivar. The results obtained were summarized as follows; Cold tolerance of the P-Tcl was better than those of the wheat cultivar Chokwang, triticale varieties Suweon #1 and Suweon #2, and comparable to local rye. Culm length of P-Tel was 113cm that was intermediate between the wheat and rye, and its culm thickness was thiner than the checks except the rye. Lateness of heading and maturing date of the P-Tel seemed to be over-dominant. However, flowering date after heading was 3 to 7 days earlier than the Suweon #1 and Suweon #2. Yield potential of the P-Tel was poor in comparision with the triticale cultivar Suweon #1 and Suweon #2 which was attributed to the low fertility and less number of the heads per squ are meter. If it was . improved the low fertility and less number of the valid tillers through the cross with the good secondary triticale it seemed to be an useful material for triticale breeding, expecially for improving cold tolerant winter triticale varieties in Korea.

Hay and haylage as forage are increasing in preference for cattle feed. Triticale (X Triticosecale Wittmack) is growing up as a forage crop due to its high production and feed value in South Korea. It is difficult to determine the harvesting stage of triticale for producing hay or haylage with the highest forage value and quality because feed and nutritional value by growth stages of triticale were not known in South Korea yet. In this study, we analyzed forage values, pH, and contents of organic acid, to confirm feed value and quality by growth stages of triticale. The triticale 'Joseong' was sown in the spring of 2022. The sample was prepared in 5 stages: seedling stage, booting stage, heading stage, 10 days after heading, and 20 days after heading. The triticale was dried under 10% and to about 50% moisture for hay and haylage respectively, and then both triticales were fermented anaerobically at room temperature for 40 days. The pH value in all hay and haylage became lower as the triticale was grown up, although the pH value of all triticale hays and haylages ranged between 7.05-5.68. The content of lactic acid in all triticale hays was almost meaningless. The contents in the haylage of the seedling stage were the highest (2.39%) among the haylages, even though those of 20 days after the heading stage (1.67%) were the lowest, which showed a similar tendency with pH value. Conclusionally, the results implied that the feed value and quality of triticale haylage were affected by harvesting time but not hay.

This experiments was conducted to investigate the influence on growth of rye, triticale with legume and investigated their productivity, feed value and stock carrying capacity in order to select the appropriate forage species in the central region of Korea. In the results, Rye+Red clover showed 5.2ton/ha of dry matter yield. But there was no significant difference with Triticale+Red clover and Rye in upland field. In paddy field, Rye+Hairy vetch showed 5.2ton/ha, but there was no significant difference with Triticale+Hairy vetch and Rye. Mixture effects with Rye, Triticale and Red clover, Hairy vetch by relative yield were more than 1.00 compared to monoculture, and their mixture effect was recognized in upland and paddy field. Relative feed value was highest in the applications of Triticale mixture in upland and paddy field. The average value of $K_{CP}$ and $K_{TDN}$ showed the highest one as 2.75head/ha/yr in Rye+Red clover in upland field and 2.84head/ ha/yr in Triticale+Hairy vetch in paddy field. According to the results, Rye+Red clover in upland field and Triticale+Hairy vetch in paddy field were considered to be the most appropriate winter forage crops for the central region of Korea in terms of productivity, feed value and stock carrying capacity.

This paper reviews the present situation of Triticale cultivation and examines the potentiality of contribution to livestock as well as poultry sector in Bangladesh Agriculture. Triticale is a human-made cross between rye and durum wheat that has the ability to produce quality green fodder, and then re-grow after first and second cutting to produce grain. In Bangladesh, it is a non-traditional cereal that grows well during the cool and dry Rabi season (November-March) when fodder and feed scarcity is a major limiting factor for ruminant livestock. In Bangladesh Triticale was started to grow in the late Ninety's. The scientists of Bangladesh Agricultural Research Institute (BARI) were first introduced triticale in Bangladesh. Still now the situation of Triticale is grown as fooder and feed in Bangladesh within the scientists under trial. High quality grass fodder was obtained by cutting green triticale plants twice, at 35 and 50 days after seeding, while later the ratooning tillers produced grain to a yield of 1.1-2.4 t/ha of grain for poultry feed or human food. Triticale straw was twice as nutritious as rice or wheat straw and its grain contained more protein than other cereals. Researchers and farmers have also successfully made triticale hay and silage from a mixture of triticale green cuttings, rice straw and molasses. A feeding trial at Bangladesh Livestock Research Institute(BLRI), Savar station showed a large(46%) increase in cow live weight gain and a 36% increase in milk yield (but no change in milk quality or dry matter intake) in cows fed triticale silage compared with those fed rice straw over a period of nine weeks. In another feeding trial, it was found that triticale grain was a good replacement for wheat in the feed blend for chickens in Bangladesh. So it will be a good chance to alive our livestock as well as poultry sector if triticale enters to our existing cropping system as fodder cum grain. The challenge in Bangladesh is to identify fodder technologies that match existing small-scale farmer cropping patterns without needing major inputs or increasing risks. Preliminary field experiments revealed that triticale is a crop with good potential to produce quality fodder and grain for small scale farmers in Bangladesh.

This experiment was carried out to obtain the information on the crossability, germination rate, and pollen viability of the progeny from the cross between hexaploid triticale cv. Sinkihomil and five hexaploid wheat varieties. The results are summarized as follows. Seed set was 28.8 to 41.8% (ave-raged 34.1%) in the cross between triticale and wheat, which resulted in 3.61% in F$_2$(selfed F$_1$), 3.99% in F$_1$/P$_1$ 21. 9% in F$_1$/P$_2$ respectively. However, seed set was extremely low in reciprocal crosses when triticale was used as male. In the backcross, crossability was higher in F$_1$/wheat and triticale/F$_1$ than that in wheat/F$_1$ and F$_1$/triticale, respectively. Germination rate of the crossed seed was 95% in F$_1$ 66.3% in F$_2$ (selfed F$_1$), 62.0% in F$_1$/P$_1$ and 81.0% in F$_1$/P$_2$ from the cross between triticale and wheat, respectively. When triticale cv. Sinkihomil was used as male, seeds were degenerated because of the failure of endorsperm development. This might be caused by AAABBBDDR genome constitution in the cytoplasm from a hexaploid wheat. Pollen fertility of F, plant was averaged 34.1% in the cross between triticale and wheat. Significant positive correlation between the pollen fertility and seed set rate in the cross between triticale and wheat were detected.

The objectives of this study were to develope the economical process for bioethanol production from domestic triticale and investigate optimal fermentation conditions such as temperature, time, and enzyme concentration used to pre-treatment process. Triticale mash, containing 148 g of total sugar per 1 L of mash, was fermented with Saccharomyces cerevisiae CHY1011 at $33^{\circ}C$. Fermentation of mash supplemented with enzyme was completed within 48-60 hours, and the ethanol yield was 410.9 L/tonne of dry base. On the other hand, fermentation of mash without enzyme addition was completed within 36-48 hours, but the ethanol yield was 342.2 L/tonne of dry base. For optimal bioethanol production from triticale, viscosity reduction enzyme was added in the pre-treatment process, and the fermentation rate of triticale was 92.0-94.2%. In addition, the results showed that bioethanol production of triticale by low-temperature pre-treatment would provide higher ethanol production efficiency and lower operating costs.
