During a study of acarine biodiversity, a phytoseiid mite was collected from soil samples under the rose of Sharon plants. The specimen was identified as Neoseiulus harrowi Collyer, 1964, which was previously only reported in New Zealand and Australia, and is thus a new record for Korean phytoseiid fauna. Neoseiulus harrowi is morphologically similar to N. makuwa (Ehara), but distinctly different in two characters: shorter length of two posterior setae (Z4, Z5) and a forked atrium of spermatheca longer in N. makuwa than in N. harrowi in females.

Due to abnormal weather conditions such as high temperature, the management of greenhouse rose farms is getting worse. In order to enhance the competitiveness of these farms, new measures are needed to improve their management performance. Therefore, this study suggests alternatives to improve the efficiency and productivity by identifying the causes of inefficiency of greenhouse rose farms in terms of management performance analysis through DEA analysis and MPI analysis. As a result of DEA analysis, the average TE of farmers increased from 0.867('16) to 0.905('17), but decreased to 0.850 in 2018, indicating that it was inefficient. In order to increase the management efficiency of farmers, efforts to preferentially reduce the costs (equipment, employment labor, fertilizer, facilities, seeds) that cause inefficiencies are needed. As a result of MPI analysis, TECI decreased from 1.044(T2) to 0.939(T3), which was the cause of the MPI decrease, and the TCI was rather increased from 0.958(T2) to 0.969(T3). In other words, it means that the decrease in productivity is due to insufficient utilization of potential production technology rather than the slowing of technological progress. This implies that it is important to provide technical guidance on utilization after technology dissemination.

A new standard rose cultivar 'Happy Day' was bred from the cross between pink standard cultivar 'Vivaldi' and pink standard cultivar 'Medeo' at the National Institute of Horticulture & Herbal Science. The first cross was in 2003 and 'Happy Day' was finally selected in 2008 after investigating characteristics for three years from 2006 to 2008. 'Happy Day', a pink standard cultivar grows vigorously and has powder mildew resistance. The major characteristics of this cultivar are $160stems\;m^{-2}$ per year in yield, 79.2 cm in length of cut flower, 9.9 cm in flower diameter, 28.8 in mean petal number, and 11.8 days in vase life. This cultivar can be propagated by both cutting and grafting. The consumers' preference of this cultivar is relatively higher than that of control cultivar, 'Nobleless'.

A new poinsettia cultivar 'Heidi' was bred by the National Institute of Horticultural and Herbal Science (NIHHS) in 2004. A cross was made between 'Freedom Rose', a variety with vigorously growing deep pink color, and 'Red Velvet', a variety with dark green leaves and red bracts in 2001. 'Heidi' was finally selected in 2004 after the investigation of the growth and flower characteristics from 2002 to 2004. It has velvety red colored elliptic bracts and transitional leaves, and medium intensity of rugosity between bract veins. Leaf blade is dark green, ovate shape and lobes are shallow. Petiole length is relatively short and stem color is reddish. 'Heidi' has free-branching ability and plant height is short. The bracts and transitional leaves are fully colored 7.5 weeks after short day commencement.
