초록
‘Jowoo’, an early maturing, high biomass yielding rice (Oryza sativa L.) cultivar with high feed value and multiple disease-insectresistance, was developed for winter forage crop-whole crop silage (WCS) rice double cropping. It was derived from a cross between a highbiomass and multiple disease resistant line ‘Suweon519’ and an early flowering, high yielding Tong-il type variety ‘Gaya’ that harbored Bph3and BPH26, conferring brown planthopper (Bph) broad resistance. This cultivar had a growth period of approximately 106 days from seedingto heading, 97 cm culm length, 24 cm panicle length, 12 panicles per hill, 120 spikelets per panicle, and 1,000-grain weight of 22.1 g asbrown rice in the central plain region of Suwon. This early flowering rice variety was tolerant to premature germination and cold stresses,especially showed higher grain fertility than ‘Nokyang’ at a cold-water (17℃) irrigated screening nursery. Further, ‘Jowoo’ exhibited high lodgingresistance in the yellowing ripening stage, an optimal period for harvest. In addition, ‘Jowoo’ was resistant to leaf and neck blast, bacterialblight (race K1, K2, K3, K3a), rice stripe virus, and small Bph and was also moderately resistant to Bph. Its average dry matter yield forthree years reached 18.2 MT/ha, the highest among early flowering rice varieties and 19% higher than that of ‘Nokyang’. This cultivar had72.2% total digestible nutrients, which is also higher than that of ‘Nokyang’. In the Korean peninsula, ‘Jowoo’ grows well in the centraland southern plains and can be harvested 30 days after heading. This helps improve its feeding value and digestion rate in livestock (GrantNo. 8133).
