This experiment was conducted to breed a very early maturing variety of Italian ryegrass (Lolium multiflorum Lam.) in Grassland and Forage Crops Division, National Institute of Animal Science, RDA, Cheonan 2015-2017. The new variety of Italian ryegrass, 'Green call 2ho' is a diploid variety with green in leaf color and has semi-erect growth habit in late autumn and erect growth habit in early spring, 'Green call 2ho' was in heading date as a early-maturing variety April 24. Also 'Green call 2ho' was narrower by 2 mm in flag leaf width, longer by 2.5 cm in flag leaf length and shorter by 3 cm in plant height than those of the control variety, 'Florida 80', respectively. 'Green call 2ho' was also thicker by 0.33 mm in stem thickness and strong in winter hardness. Dry matter (DM) yield (11,688 kg/ha) of 'Green call 2ho' was 7% higher than that of 'Florida 80'. Total digestible nutrient (TDN), crude protein (CP) and relative feed value (RFV) of 'Green call 2ho' were 61.3 %, 9.8 % and 98.2, respectively which are 2.6, 0.6, and 8.4 % higher, respectively than those of 'Florida 80', respectively. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) of 'Green call 2ho' were 34.9 and 58.5 % which are 3.3 and 2.7 % lower than those of 'Florida 80', respectively.

문제 정의
However, recently developed domestic varieties of early maturity have early heading date from late-April to early-May, and seed harvesting can be carried out before the beginning of the rainy season in early-June that it can make dry and select them, which makes them attractive for seed production. This study was conducted to evaluate the growth characteristics and productivity of Green call 2ho, an Italian ryegrass species with high yielding and early maturing variety in South Korea.
제안 방법
Experments were conducted from 2015 to 2017 in Yunchun, Cheonan, Yesan, Iksan, Jeju. The experimental plots were laid out according to three replications of a randomized block design. The size of the experimental plot was 6 ㎡(2m x 3m).
Winter hardness test was evaluated by visually inspecting the number of surviving and dead individual plants in early spring and calculating the survival rate of the field.

Total digestible nutrients (TDN) were calculated using the Menke and Huss method (1980), and in vitro dry matter digestibility (IVDMD) was examined with the method proposed by Tilley and Terry (1963). Acid detergent fiber (ADF) and neutral detergent fiber (NDF) were analyzed using the Goering and Van Soest (1970) method. Analysis of variance of the dry matter yield of this experiment was carried out with an SAS(2004) package program and the significance of the differences(p<0.
and the green forage weight was converted into dry matter yield using the dry matter rate. In terms of feed value analysis, crude protein (CP) was analyzed with the AOAC method (1990). Total digestible nutrients (TDN) were calculated using the Menke and Huss method (1980), and in vitro dry matter digestibility (IVDMD) was examined with the method proposed by Tilley and Terry (1963).
