Phalaenopsis amabilis cultivated have many constraints such as the appearance of fusarium wilt disease caused by Fusarium oxysporum. Plantlet P.amabilis which resistant to F. Oxysporum was selected in the solid Vacin and Went (VW) medium was added with salicylic acid at concentrations of 65 ppm, 75 ppm, and 85 ppm, compared with controls (0 ppm). The goals of the research were to study and determine of: 1) The SA concentration of planlet P. amabilis selection tolerant; 2) The proper concentration of AS during in vitro selection for suppressing the Fo. The research was carried out in December 2015 to February 2016 in the Botany Laboratory (in vitro research room), Departement of Biology, Faculty of MIPA, Lampung University. The result showed that: 1) The SA tolerant concentration for plantlet selection with P. amabilis was between 65 ppm - 85 ppm. 2) The 85 ppm of SA was effective for suppressing the Fo compared to 65 ppm and 75 ppm. Keywords: Phalaenopsis amabilis, salicylic acid, Fusarium oxysporum, In vitro, Resistance.

The use of resistant cultivars is an effective method for the control of banana (Musa spp.) Fusarium wilt caused by race 4 of Fusarium oxysporum f. sp. cubense (Foc4). However, selection of disease-resistant cultivars requires large-scale field evaluations and is time-consuming. Development of early, reliable, and reproducible selection strategies can speed up this process. Sequence characterized amplified region (SCAR) markers have been widely employed in the resistant breeding of many crops. However, to date, there have been no reports about the presence of plant disease resistance-related SCAR markers in mitochondrial genome yet, which also plays a very important role in plant defenses. In the present study, a sequence-related amplified polymorphism (SRAP) marker, a specific fragment of 829 bp, was identified. This fragment could be amplified from Foc4-susceptible but not from the resistant cultivars. It was located in banana mitochondrial genome and mapped near the putative cytochrome c biogenesis ccmB-like mitochondrial protein. This fragment was then successfully converted into a SCAR marker, namely Mito-Foc-S001, which was found to be able to discriminate the resistance from susceptibility to Fusarium wilt disease of bananas with the discriminatory power of the new mark being 96.88%. Thus, this marker can be used in banana (Musa AAA Cavendish) breeding for Fusarium wilt disease resistance.
