Abstract

A new graft cactus (Chamaecereus silvestrii f. variegata) cultivars "Yellow Ttree" was developed at Cactus Research Institute, Gyeonggi-do A.R.E.S. in 2007. GC013001 and GC0110703 were crossed in 2005 and we got 42 seedlings from this combination. After pedigree selection in 2005, one cultivar were finally selected through the test of specific character in 2007 and named as "Yellow Ttree". "Yellow Ttree" has cylindrical shape of yellow color with 13~14 ribs. Formation of its offshoots is concentrated on the lower part of the plant. This cultivar is able to produce 13.9 offsets shoots per plant and its offshoots are hard.

기존 산취계통은 자구 탈립이 잘되고 저장성이 낮으며 구색의 퇴화가 빠른 단점 등을 보완하고자 GC013001${\times}$GC0110703 조합에서 구색이 선명한 황색이고 관상가치가 우수한 GC052209 계통에 대한 농가실증시험 및 품평회를 마치고 명명된 "Yellow Tree"의 구색은 황색이었고 결각의 형태는 둥근형으로 관상가치가 우수하였으며, 구의 형태는 원형으로 8~9개의 결각을 가졌다. 가시는 갈색으로 반직립 하였으며 가시길이는 짧았다. 자구수는 개로 생산력이 우수하였다.
