摘要： 运用简单相关、多元回归和偏相关分析，以及通径系数分析，研究一个玉米双列杂交组中21个基因型的五个光合作用性状与生物学产量和籽粒产量之间的关系。结果表明灌浆期的CO2交换率、单株总叶面积、实际籽粒灌浆期长度以及经济系数等性状对籽粒产量有正的直接效应；其中前三个性状也对生物学产量有正的直接效应。这表明在玉米

Abstract: Relationships between five characters of photosynthesis of the 21 geno-types from a diallel cross in corn (Zea mays L.)and biological and grainyield were studied by utilizing simple correlation,multiple regression,par-tial correlation and path-coefficient analysis.The results show that the CO_2oxcha
