Three sets of experiments were involved in this study. They were carried out at the Department of Horticulture and Agricultural Biotechnology, Yezin Agricultural University from October, 2012 to August, 2014. In experiment I, China aster seeds collected from four locations: Yangon (YGN), Taungoo (TGO), Pyinmana (PMA), and Pyin-Oo-Lwin (POL), were employed to evaluate horticultural traits and phylogenic relationships among Callistephus accessions by using Power Marker version 3.2. Callistephus accessions clustered into three main groups in UPGMA (unweighted pair-group method) dendrogram. Group I and II included Pyin-Oo-Lwin seed source, and group III contained Yangon, Taungoo, Pyinmana seed sources. In experiment II, seeds from Group III, the same morphological characteristics in the UPGMA dendrogram, were selected to evaluate their horticultural traits in two different growing seasons. Floral bud initiation (41.87), first flower opening (63.37) and 50 percent flowering (65.50) were later, but number of leaves (19.75) and plant height (51.00 cm) were higher in winter season than in rainy season.
