This study analyzed taxonomy of mango cultivars grown in Indonesia based on morphology and agronomy characters. It obtained 84 recognizable cultivars. They are grouped into eigth main cultivar-groups (e.g. Berem, Madu, Cedong, Colek, Bapang, Arumanis, Kepodang, and Kebo) and eigthteen cultivar-groups. The 'Lalijiwo' cultivars synonym with Thaber ', Tabar', 'Curih' whereas 'Arummanis ' synonim with 'Cadung '. Meanwhile, the cultivar 'Kates277 ' which is a member of Colek cultivar main group is homonim with the cultivar 'Kates' in Arummanis cultivars main group. Furthermore, the cultivar Nanas93 (one of Madu main group cultivar) that different with the cultivar 'Nanas71 'which is categorized as member of Bapang main cultivar group.

Sukma, Dewi; Poerwanto, Roedhy; Sudarsono; Khumaida, Nurul; Wiyono, Suryo; Artika, I Made A number of Trichosanthes species has been reported as a source of bioactive protein associated with defense mechanisms such as chitinase. Chitinase and peroxidase of crude protein extracted from leaves, roots, in vitro colli and shoots ofT. tricuspidata had been analysed. Colli were induced on MS medium containing combinations of I uM NAA +.1 pMBA (Kl), 2 fiMNAA + 2 pM B A (K2), 3 pM NAA + 3 uM B A (K3), or 4 pM NAA + 4 pM B A (K4). Shoots were cultured in MS with 1 mg/l of BA, while leaves and roots were harvested from six-month old plants grown on the field. Results of the experiment suggested that KI-K4 medium could be used to induce colli although weight of colli from all medium composition was not significantly different (0.19-0.31 g/explant/4 weeks). Colli from Kl medium had the highest of total crude protein content (3.24 mg/ml). The highest of chitinase activity was found in in vitro shoots (6.51 mM pNP/hour/mg protein) and the highest peroxidase activity was in the plant roots (0.25 A 420/minute/mg protein).
