Abstract ▼

This experiment was carried out to develop functional whole crop silage rice cultivars, to know adaptability and productivities of silage corn, sudangrass, grassess in paddy field condition, and to know quality, palatability of animal, and production quality of whole crop rice in paddy field from 20

This experiment was carried out to develop functional whole crop silage rice cultivars, to know adaptability and productivities of silage corn, sudangrass, grassess in paddy field condition, and to know quality, palatability of animal, and production quality of whole crop rice in paddy field from 2007 to 2011. The main achievements through the project are summarized at following sentences. The institutes conducted a total of 20 crosses, 11 crosses for F1, 7 crosses for F2 and 11 crosses for F3 for further selection. Main cross parent is Gillim collection 1, Danmi, and LK1A-2-12-1-1. Final, through the yield trials for functional whole crop silage rice, one new promising line was selected from the replicaed yield trials, and four lines is selected for replicated yield trials of next year. Polyphenol contents, DPPH radical sacvenging activity and ABTS radical sacvenging activity of SR30719-16-1 line of purple leaves had the highest. And other lines were also contains a lot of antioxidants. For these lines will continue breeding. Among agronomic characteristics, Kwangpyongok hybrid appeared to be somewhat strong for waterlogging and good characters for stay green, lodging, disease, insect more than other varieties. Kwangpyongok hybrid showed the highest in the fresh yield (28,878kg/ha) and TDM yield (7,354kg/ha) in paddy field of southern region of Korea. Among agronomic characteristics, ‘Kangdaok’ and ‘Kwangpyongok’ hybrid were somewhat strong for waterlogging and good stay green, lodging, disease and insect resistance. The dry matter yield of ‘Kangdaok’ and ‘Kwangpyongok’ hybrid were the highest among korean corn hybrids. Among growth characters of 10 Hybrids, ‘Sordan 79’ hybrid was somewhat strong for waterlogging, and higher sugar content and very good at the 2nd regrowth and disease resistance in the middle and southern Korea. Fresh yield of ‘SX17’hybrid was the highest as 67,072kg per ha among 10 Sorghum and Sorghum ×Sudangrass and Sudangrass hybrids. The dry matter yield of ‘SX17’ hybrid was the highest as 16,919 kg per ha. Among pasture species, Italian ryegrass and Tall fescue were somewhat good for waterlogging, production, and disease and insect resistance. Dry matter yields of Italian ryegrass and Tall fescue were the highest among six species in the middle and southern Korea. Whole crop rice varieties showed high quality and palatability. The optimum harvest stage of whole crop rice was yellow stage. Lactic and total organic acid contents of rice silage was higher than rice straw silage, and similar to corn silage. The silage quality of whole crop rice was higher than corn silage and rice straw silage. The palatability of whole crop rice silage was similar to corn silage in Hanwoo and dairy cattle. Consequently, there are many possibilities for animal production and forage production in paddy field.
