농가 선호도가 높은 분홍색 비모란 선인장 ‘Yeonbit’는 분홍색 품종 ‘Yeonsi’을 모본으로, 분홍색 ‘Yeonsil’ 품종을 부본으로 하여 2011년에 교배하여 육성된 교배종이다. 종자를 70% C2H5OH와 2% NaOCl로 멸균처리한 후, 100mL 삼각플라스크 0.1% 활성탄이 첨가된 Kyoto 배지에 파종하였다. 발아된 유묘는 기저부를 잘라 기배계대 배양된 어린 삼각주에 접목한 후 동일한 배지가 첨가된 시험관에 치상하였다. 6개월 재배 후 온실로 옮겨서 순화과정을 거쳤으며, 기외에서 매년 접목을 하였으며 총 4번을 접목하여 2013년부터 2015년까지 총 3회에 걸쳐 생육특성을 조사하였다. ‘Yeonbit’ 품종은 편원형 모양과 분홍색 구색을 가지고 있다. 그리고 7~9개, 평균 8.0개의 능(rip), 갈색의 직립형 짧은 가시, 그리고 혹(tubercle)이 돌출된 형태로, 모구가 구성되어 있다. 정식 10개월 후 ‘Yeonbit’ 품종의 구직경은 34.5mm였으며 자구는 모구와 같은 분홍색으로 평균 15.4개가 생성되었다. 2015년 육성계통 평가회에서 ‘Yeonbit’ 품종은 기호도 점수 3.7을 받았다. 2017년 6월 12일에 이 품종은 국립종자원에 등록되었으며 종자산업법에 의해 품종보호(등록번호 6752)를 받게 되었다.

The cultivar of moon cactus, ‘Yeonbit’ with pink color, was bred by National Institute of Horticultural & Herbal Science (NIHHS) in 2015. For breeding a pink cultivar with high preference, the pink color cultivars 'Yeonsi' and 'Yeonsil' were crossed in 2011. After 2 months, the seeds were harvested and separated from the peel. And then they were sterilized by C2H5OH 70% and NaOCl 2%, and then sowed in 100 mL mass flask filled with Kyoto medium + charcoal 0.1%. The bottom of shoot was cut, grafted into a young vine cactus, Hylocereus trigonus in vitro, and then planted into test tube with the same medium. After 6 months, a young moon cactus was secondly grafted into vine cactus in vivo. The growth was surveyed three times from 2013 to 2015, according to the guideline for the conduct of tests for distinctness, uniformity, and stability of Gymnocalycium mihanovichii. ‘Yeonbit’ has flat round shape and pink skin (RP N47B). This cultivar has 8.0 ribs in average. The spine had brown color. The spine averagely grew to 5.2 mm in a straight shape. The shape of tubercle on the rib was projecting. This was 34.5 mm in diameter and averagely produced 15.4 offsets at 10 months from planting. The preference score of this was 3.7 on a five-point scale. On June 12th 2017, ‘Yeonbit’ was registered (registration No. 6752) and is now protected by Korean Seed Industry Law.
