Breeding of a Bright Pink Gerbera 'Yeunhwa' for Cut Flower

摘要

A new bright pink gerbera (Gerbera hybrida Hort.) 'Yeunhwa' was developed by crossed 'Beauty' and 'Ansofie' at Yoengju Agricultural Technology Extention Center. One breeding line, 2001-20, was selected in 2000 based on flower color and productivity onthe first selection. A backcrossed line, 2002-202, was selected by crossing '2001-20' and 'Ansofie' on Daegu, Suwon and Yoengju Agricultural Technology Extention Center in 2001. Characteristics trials were conducted three times from 2003 to 2005. Bred cultivar 'Yeunhwa' showed pink color (RP 62-A), green center, semi-double type and middle size flower with stable flower shape. The average productivity for three years was 70.0 stems per plant and increased 35.9% compared to that of cultivar 'Rozalin' which showed 51.5 stems. The vase life was 7.5 days. After winter season, the survival rate of cultivar 'Yeunhwa' was higher than that of cultivar 'Rozalin'.
