The new cultivar SM 7661 with the red colored mini type characteristics, was derived by artificial crossing between Phal. Golden Sun(female parent) and Phal. Princess Kaiulani(male parent). From 2005 to 2006, 250 individuals were cultivated over two years. Among them, an elite individual number ' ' with excellent growth and flowering characteristics was finally selected by intensive selection process. The stability and uniformity of the cultivar was confirmed through the first and second characteristics tests in 2007 and 2008 and named as 'SM 7661'. SM 7661 produces dark red (RHS#185B) flowers of round shape and spreading mini type with size of 5.7 and 5.8cm in flower length and width, respectively. SM 7661 is regarded as raceme flower type with many flowers and good volume and suitable for small flower pot market. The leaf of SM 7661 is rowing horizontally and 13.8cm in length and 7.2cm in width. This cultivar also possesses no genetic variation, fast in vitro propagation and easy growing due to vigorous growth habit. This SM 7661 is registered (Reg.#:3826)to Korea Seed & Variety Service(KSVS) in December 21, 2011 and PBR(plant breeder's right) is currently controlled by Sangmiwon Orchid Company, Korea.

SM 7661의화색은진적색으로모본인 Phal. Golden Sun과유사하지만보다선명한적색 (185B) 소형계통으로, 화색과동일한적색 (185B) 의순변이있다 (Figs. 2, 6, Table 1). 화형은둥글며평피기로안정된느낌을준다. 이와같이신품종 Phal. SM 7661 꽃의전체적인형태와화색은부본보다모본과매우유사하다 (Fig. 2, 6). 소화의길이와폭은각각 5.7cm, 5.8cm 로대조품종 Queen Beer의 4.5cm, 5.6cm보다길이는 1.2cm 길었으나폭은거의비슷하였다. 화서장은 24.1cm로대조품종의 27.4cm 보다약간짧았다. 소화수는 15.3개로대조품종 16.0 개보다약간적었다 (Table 1, Fig. 6). 또한소화가좌우로균일하게배열되고소화간의간격이적당하고전체적으로균형이잡혀

Golden Sun과 Phal. Princess Kaiulani를각각모본과부본으로인공교배하여육성한 F1개체중에서선발한진적색소형계통의신품종 이다. 2005년부터 2006년까지 2년에걸쳐실생 250개체를양성하였다. 이들중에서재배시생장과개화특성이우수한개체 을최종적으로선발하였다. 2007년과 2008년 2년간 1차, 2차특성검정을통하여재배품종으로서의안정성과균일성을확인하고 SM 7661로명명하였다. SM 7661은화색이진한적색 (185B) 이다. 화형은둥글고평피기로안정되어있다. 꽃의길이와폭은각각 5.7cm, 5.8cm로소형이다. 화서는총상으로소화수가많고볼륨이있기때문에소형분화에적합하다. 잎의길이와폭은각각 13.8cm, 7.2cm이며엽형은수평이다. 기내증식율이높고변이가거의없으며잘자라고강건하기때문에재배관리가용이하다. 상미원에서 2011년 12월 21일품종등록 ( 등록번호제3826호 ) 하여종자산업법에의해보호받고있다. 사사이논문은부산대학교기본연구지원사업 (2년) 에의하여연구되었음.
