The field experiment has been caring out on a good rye soil complex with winter wheat planted in various crop successions. The experiment was designed as a split plot in which the 1st factor level was winter wheat and oilseed rape as fore - forecrops. Followed by them six forecrops (spring triticale, oat, yellow lupine, blue lupine, and two intercrops of triticale - lupines) were planted on plots and the winter wheat in their succession. The objective of this study was to compare five forecrops: triticale, two lupines and two intercrops to the stand after oat. The effect of fore-forecrops and forecrops for the winter wheat yield and the grain energy accumulation was investigated. The previous results indicated clearly that the spring triticale - lupine mixtures, as the forecrops are valuable for the winter whet production, especially in permanent cereal succession. Winter wheat responded to this forecrops by increased accumulation of the grain energy. The relations between the type of fore-forecrops and subsequent forecrops were statistically proved. Meanwhile, there were no significant differences between fore-forecrops on the grain yield of winter wheat. The study has been given the assumption that intercropping of spring triticale with lupines may be relevant factor in alleviation of the negative results of permanent cereal succession
