Adaptation study of 10 lines/varieties composite and hybrid maize was conducted, aiming to get adaptive lines/varieties on dryland farming agroecosystem  in Maluku. The location of study was in Waipirit Village, Kairatu Sub-district, seram District on farmers land by involving the participation of farmers.  The investigation was arranged in completely Randomized Block design with 3 replications.  Ten composite and hybrid pre-eminet lines/varieties and 2 local varieties were tested for adaptation.  The area of study  plot was 4 m x 5 m and the  distance between treatment plots was 1,5 m.  Plant spacing applied was 75 cm x 40 cm (2 plants/hole).  Lines/varieties studied were Sukmaraga, Srikandi kuning, Bisma, Palakka, B 11209, MR-14, NE I, MR-4, Local Unggu and Lokal Pulut Putih.  fertilizers were given in holes (sidedress application) with distance around 5-7 cm from plant stem.  The doses of fertilizers were 300 kg  ha-1 Urea 200 kgha-1 SP-36, 100 kg ha-1 Kcl, and 2 t ha-1 manure.  Urea was applied twice, that is 100 kg urea and all SP-36 and KCl at 7 days after planting (DAP) and the rest of urae (200 kg) was applied  at the last soil tillage, as much as 2 t ha.  Parameter observed were the percentage of growing plant, plant height cob height, age of male flowering > 50%, age of female flowering > 50%, cob lenght, cob weight, weight of 100 dry seeds, yield of maize and the number of plants with disease/pest attack.  Other data required was preference of consumers and farmers to pre-emiment line/variety, rainfall data during the study, and other supporting data.  Agronomy data was analysed statistically and the value differences between treatments was done by t test.  results of this research  aindicated that the composite pre-eminent varieties showed better growth and yield components compared to the yield of local lines and varieties.  Sukmaraga variety gave highest yield (12.02 t ha-1), followed by Palakka, Srikandi kuning, and Bisma varieties as much as 9.90 t ha-1, 9.63 t ha-1, and 8.26 t ha-1 respectively.  The expected lines which have prospect for acceleration of release as high yielding varieties were NE I, MR-14 and B11209 because the yield was above the average national maize yield, as  much as 8.17, 7.49, and 4.65 t ha, respectively.
