Growth Characteristics and Productivity of Cold-Tolerant Italian Ryegrass New Variety, Kowinmaster in the Northern Part of South Korea
1. Introduction Italian ryegrass (Lolium multiflorum Lam.) has good productivity and high feed value of forage but its cultivation has been confined to southern part of south Korea because of its poor cold tolerance. Thus, in Korea, improvement of cold tolerance in Italian ryegrass is very important to increase the productivity and to widen the cultivation area of Italian ryegrass. 2. Materials and Methods This study was conducted in the Grassland and Forages Division, National Institute of Animal Science, Rural Development Administration, South Korea during 20032006. Italian ryegrass Hwasan 101, Florida 80 and Kowinmaster were sown in narrow strips in plots 2m by 3m in randomized block design on Sept. 25-30 in suwon and on Sept 20-25 in Yonchun. Winter field survival was checked in early spring. Italian ryegrass was harvested in heading time of variety for evaluating on dry matter productivity. 3. Results and Discussions Characteristics of Italian ryegrass varieties are shown in Table 1. Italian ryegrass Kowinmaster was a diploid variety with light green leaf color and had growth habit of medium in autumn and semi-erect type in spring, respectively.
