The study was conducted to obtain some genetic information on crossbred. from crossbreeding of Korean native goats and Saanen goats. Eight hundred and seventy head, of purebred and crossbred goats raised at the Livestock Experiment Station from 1969 to 1975 were investigated to get the data on their body weight, body measurements and milk yield. Those data were analysed to estimate the additive and non-additive effect; as well as maternal effects by different mating systems. The results obtained are summarized as follows ; 1. The additive effects on body weight, withers height, body length, cheat girth and milk yield in single crossing(SN) of Korean native goats and Saanen goats were estimated 86.54, 106.89, 104.95, 98.44, and 89.41%, respectively, and non-additive effects 13.46, -6.89, -4.95, 1.56 and 10.59%, respectively. 2. In the second generation of F₁ back-crowed to Saanen breed for grading up S (SN) the additive, non-additive and maternal effect, were estimated 82.26, 5.94 and 11.80% for body weight, 102.10, -3.13 and 1.02 for withers height, 105.00, -2.35 and -2.64% for body length, 99.32, 0.77 and -0.09% for chest girth, 105. 11, 4.38 and -9. ~19$quot;/o for milk yield, respectively. 3. In the third generation of S (SN) back-crossed to Saanen breed for grading up S (SSN) non-additive and maternal effects were estimated 8-1.17, 2.92 and 12.91% for body weight, 101.66, -1.5% and -0.13% for wither; height, 102.58, -1.13 and -1..15% for body length, 101.24, 0.38 and -1.62% for chest girth, 103.73, 1.88 and -5.6% for milk yield, respectively.
