摘　　要：对有关产量性状的通径分析结果表明,在本试验条件下,无论从基因型效应抑或环境效应来看,斑茅蔗BC1后代品系单茎重对蔗茎产量的直接效应都是最大,其次为小区有效茎数;而决定系数计算结果则表明,它们对蔗汁锤度的贡献不大,应进一步寻找另外的影响斑茅蔗BC1后代品系品质的主要相关性状或因素。The path coefficients of the yield characters were analyzed in this paper by using BC1 lines of E. arundinaceus （Erianthus arundinaceus （Retz） Jeswiet） from GSIRI （Guangzhou Sugarcane Industry Research Institute）. The results indicated that both the genetic correlation and environmental correlation of stalk weight to cane yield was respectively higher than that of the other yield characters, and their direct effect were also the largest, followed by stalk number, the results of decision coefficients showed that the contribution of these characters to brix in juice was very little. Therefore, more attention should be paid on other characters which had the great importance to the quality of BC 1 lines orE. arundinaceus.
