Alternation of generations can be divided into two basic types, one for the same shape alternation of generations, the sporophyte and the gametophyte in the morphology similar size, only cytology and physiology are different, such as Ulva, etc.; another type of shape alternation of generations, that is, in the sporophyte and gametophyte morphology and size are also significant differences.

世代交替又可分为两种基本类型，一为同形世代交替，即孢子体和配子体在形态大小上类似，仅在细胞学上和生理上有所不同，如石莼等；另一类型为异形世代交替，即孢子体和配子体在形态结构和大小上也有明显差异。

A total of 197 F2 plants from the cross Chuanmai 42×Yr24/3*Avocet S and 726 F2 plants from Chuanmai 42×Yr26/3*Avocet S showed high resistance to CYR32 without segregations. Seedling testes with 26 PST isolates showed an identical reaction patterns for Chuanmai 42 (YrCH42), Yr24/3*Avocet S (Yr24) and Yr26/3*Avocet S (Yr26). In considering the allelic test of two F2 populations and seedling responses to 26 PST isolates as well as chromosome locations, YrCH42, Yr24 and Yr26 are likely to be the same gene.
