Abstract: [Objective] The aim of the study was to investigate the relationship between growth traits and yield of T. kirilowii and to guide agricultural production of T. kirilowii. [Method] The growth indicators of T. kirilowii, such as budding time, flowering time, maturity, leaf number and fruit number per plant, were observed. The importance and interaction of various growth traits were analyzed by correlation and main factors analysis. [Results] The variation coefficient was small within germplasms but large among germplasms. The factors affecting yield per plant was fruit number per plant, tiller number, stem thick, leaf number and plant height. The effect size followed the order of height > tiller number > blades > fruit number per plant > main stem > diameter > maturity > budding time > flowering time. [Conclusion] The tiller, stem, leaves and yield per plant are higher when fruit number per plant is higher. Comparing the relative importance of growth factors can guide agricultural production management and scientific fertilization.
