摘要： 为了解决紫苏资源鉴选中产量构成因素的问题，对贵州地区收集的50份紫苏种质资源材料进行2年2点种植，并对农艺学性状及产量构成因素进行相关及回归分析。结果表明：供试材料农艺学性状指标均有较大的变异，变异系数最大是单株总穗数，其次是单株产量。产量构成因素分析表明，株高、单株总穗数及千粒重是影响紫苏产量的重要因素。以株高、单株总穗数及千粒重与单株产量建立回归方程，发现3个因素对单株产量的贡献度分别为0.037、0.069、5.598 g。结果表明，紫苏高产育种研究应主要考虑株高、单株总穗数、千粒重指标。该研究结果将为贵州紫苏种质资源的鉴选评价，以及紫苏材料创新及品种选育研究奠定基础。

Abstract: To study the yield components of Perilla frutescens in material identification, the 50 Perilla frutescens materials from Guizhou Province had been planted in two areas for two years, and correlation and regression analysis were conducted on agronomic and yield components. The results showed that agronomic trait indexes of tested materials all had large variation，the C.V. and yield components analysis showed that plant height, spike number per plant and thousand seed weight were three most important traits in Perilla frutescens yield research, and regression analysis of yield per plant was carried out with those three factors, the results showed that yield contribution degree of the three factors were 0.037, 0.069 and 5.598 g, respectively. The results showed that the plant height, number of spikes per plants and thousand seed weight should be considered mainly in high yield breeding. These results would lay an important foundation for the material identification of Guizhou Perilla frutescens and breeding research of Perilla frutescens.
