%X To investigate the agronomic performance of India rapeseeds (Brassica juncea) under the Tibetan Plateau environment, a randomized block experiment involving 20 Indian rapeseeds materials was conducted in Tibet. The canonical correlation analysis of 4 main stem characteristics (plant height, main stem basal diameter, main inflorescence length and first branch pod number), 3 branch characters (branch height, effective branch number per plant and effective first branch number), 3 silique characters (pod length, pod width and pod beak length), 4 phenophase characters (vegetative growth days, shared days of vegetative and reproductive growth, reproductive growth days and entire growth period days) and 4 yield characters (effective pod number per plant, seed number per pod, 1000-grain weight and yield per plant) were analyzed. The results indicated that effective pod number per plant was the main factor of Indian rapeseed yield components. Silique characters were most critical for high-yield, followed by branch, phenophase and main stem characters. Main stem, branch, silique, phenophase and yield characters were closely related. The results provided the scientific basis for the development and utilization of Indian rapeseeds in the Tibetan Plateau environment.
