Genetic analysis and correlation coefficients for nutrient quality and digestible dry matter yield in forage rape

In order to obtain basic information for breeding varieties of forage rape which is suitable at the southern part of Korea, seventeen introduced varieties were grown from sep. 1986 to May 1987 at Mokpo Experiment Station, Crop Experiment Station, and yield components and nutrient quality of plants were observed. Heritabilities of CP, NDF, ADF, cellulose, lignin, IVDMD, DDMY were higher, but that of hemicellulose were relatively lower. Total dry matter yield and yield components showed highly significant positive correlations with IVDMD(in vitro dry matter digestibility) and DDMY(digestible dry matter yield). These characters mentioned above showed negative correlations with content of NDF, ADF, cellulose and lignin.
