Abstract

A new Rosa cultivar ‘Pinky Luna’ was bred at Jeollabuk-do Agricultural Research and Extension Services. In the year 2011, between ‘Rose Yumi’ of white color as a mother plant and ‘Ocean Song’ of light purple color as a father plant were artificially crossed, and 87 seeds were obtained, subsequently 66 seedling individuals were raised during the course of the next year. The ‘R111953-25’ line, which possessed pristine characteristics such as a beautiful flower shape and petal color, a fragrance, and good productivity, was selected via the characteristic trial during the years 2012 - 2013, then finally named as ‘Pinky Luna’ after investigating the characteristics, the preference, and the productivity during the years 2014 - 2015. ‘Pinky Luna’ cultivar was a standard type for cut flower with the pastel color of pale pink (petal’s surface - pinkish white, WN155C (RHS color chart), petal’s back – very pale purple, RP69D) and a sweet fragrance within the flower. The new bred cultivar possessed several morphological characteristics including medium elliptical leaf shape, a deep green (N137A) leaf color, circular flower shape, and a broad oval petal type. The flower width and height of ‘Pinky Luna’ was larger than the control cultivar ‘Ocean Song’ at 10.5 cm, and 4.1 cm. respectively, and the number of its petals were far more than those at 67.0, and in addition, the diameter of petal was wider. The cut flower length and leaf growth of ‘Pinky Luna’ were smaller than the control cultivar, however, the annual amount of average cut flowers per square of the new cultivar were 157.6, which was 10.2 more stems than ‘Ocean Song’. Vase l ife lasted longer for a period of 11.7 days, and additionally the consumer preference of cut flowers was higher than that of ‘Ocean Song’.
