Performance of Sudangrass, Sudangrass Hybrids and Sorghum-Sudangrass Hybrids for Forage Production V. Comparison of recommended cultivars of sorghum-sudangrass hybrids
수단그라스, 수단그라스잡종 및 수수-수단그라스잡종의 사초생산성 V. 수단그라스계 장려품종의 비교
Abstract
There are ten NLCF's recommended sorghum-sudangrass hybrids(Sorghum bicolor (L.) Moench), but they have not been evaluated under same environmental conditions. Therefore, a field experiment was conducted to campare forage yield and quality of the NLCF's recommended cultivars of sorghum-sudangrass hybrids at the experimental forage field, College of Agriculture, SNU, Suweon over two years. Among the ten cultivars used, G83F and NC+855 were classified as early maturing cultivars. Pioneer 988 and Sordan 79 were more resistant to leaf blight than the other hybrids. Jumbo, Sordan 79 and SX-17 were susceptible to lodging. No significant differences in dry matter yield were found among the cultivars used, but the dry matter yields of Pioneer 988, TE-Haygrazer and G83F were slightly higher than the other hybrids in 1989 and those of NC+855 and Pioneer 988 were higher in 1990. There were no marked cultivar differences in CP, ADF, NDF and RFV at the first, second and third cuts in 1990, but the ADF, NDF and RFV of sorghum-sudangrass hybrids at the third cut showed more higher than those of the first and second cut forage. In conclusion, there are no forage yield differences among the ten NLCF's recommended sorghum-sudangrass hybrids.
현재 축산업협동조합중앙회가 권장하는 수단그라스계 잡종의 장려품종은 10종이 있으나 이들은 동일한 환경조건하에서 함께 평가된 일이 없다. 따라서 본 시험은 수원소재 서울대 농대의 사초시험포장에서 2년간에 걸쳐 수단그라스계 잡종의 축협장려품종에 대한 사초수량과 사료가치를 비교하기 위하여 수행되었다. 10종의 공시품종중 G83F 및 NC
