摘　　要：通过对纤用亚麻云亚1号的不同茎粗与出麻率进行方差、表型和回归分析，结果表明：不同茎粗对出麻率的影响达极显著或著显著水平，二者表型呈抛物线变化，最佳茎粗范围值为1．0～1．5mm；非线性回归分析，Peal—reed模型和Cubicsratio模型拟合程度较高，相关系数分别为0．9494和0．9523。The correlation of stem diameter and fiber percentage of Yunya No.1 was studied by the analysis methods of variance, phenotype and regression. The results showed that different stem diameter has significant effect on fiber percentage and there is parabolic relationship between the two factors in phenotype. The fiber percentage is best when stem diameter range is 1.0 mm to 1.Smm. Peal-reed model and Cubics ratio model have high fitting degree. The related coefficients are 0.9494 and 0.9523 respectively.
