对于单次异花授粉产生一粒或几粒种子且自花授粉较容易的植物物种，要求较高的三次测验杂交设计的家系可以被其自交产生的子代家系所取代。对有无上位性的F2和F∞群体，描述了这种替代对上位性检验的敏感性以及对变异的加性和显性分量估计的可靠性的理论后果。通过对F-∞群体的三测交正常家系及其自交系的比较分析，说明了实际结果。
For plant species in which a single cross pollination yields one or few seed and self pollination is easier, the families of the rather demanding triple test cross design can be replaced by their progeny families produced by selfing. The theoretical consequences of making this substitution on the sensitivity of the tests for epistasis and on the reliability of the estimates of the additive and dominance components of variation in the presence and absence of epistasis are described for F 2 and F∞ populations. The practical consequences are illustrated by comparative analyses of normal families of a triple test cross and their selfs for the F∞ population using a population of 80 F 13 families produced from a cross between varieties 1 and 5 of Nicotiana rustica.
