  • The first commercial planting of sweet cherry in Korea is thought to be done in early 1920s. The planting area of sweet cherry in Korea is about 500 ha in 2017. Although sweet cherry is considered a minor fruit in Korea, it is one of premium fruits in market and popular among children and women, especially among pregnant women. The import of sweet cherry fruits has increased dramatically in recent years. Seedlings of Prunus lannesiana or clones of 'Colt' (P. avium × P. pseudocerasus) were usually used as sweet cherry rootstocks in Korea. During recent decades new dwarfing rootstocks for cherry such as 'Gisela' series were developed in Germany. Among them, several 'Gisela' series have been mainly used in international nurseries. In this study, we investigated optimum rooting condition of a dwarfing rootstock 'Gisela 5' in summer season cuttings. Among eight soil conditions tested, saprolite + commercial nursery soil (1:1) and saprolite + vermiculite (1:1) showed higher rooting percentage than others, showing 93.6% and 88.9%, respectively. More than 95% of 'Gisela 5' rootstocks produce roots when it was treated with IBA for several seconds just before cuttings, irrespective of concentrations (500 to 2000 mg·L-1).

  • The present experiment was carried out to compare performance, carcass characteristics and meat quality among three major meat-type duck strains in Korea. Two commercial duck (CD) strains, produced from parent stocks (PS) (Cherry Valley and Grimaud), and $F_1$ strains, self-produced by farmers, were used in an 8-week feeding experiment. Both feed conversion ratio and production index were significantly higher in Cherry Valley strain compared with the other two at the ends of 6 and 8 weeks (p<0.05). However, no differences were found in carcass characteristics and meat quality, with the exception of abdominal fat weight where Grimaud were higher than the others. Overall, the results of the current study show that Cherry Valley CD strain had higher performance among three strains tested.
