Using conventional crossing methods under natural conditions,without using embryo culture to rescue hybrid embryos,common wheat(Triticum aestivum L.,2n=6X=42,AABBDD) was crossed with Aegilops tauschii Coss.(2n=2X=14,DD),Persicum-tauschii amphidiploids(2n=6X=42,AABBDD),CIMMYT synthetic wheat(6X,AABBDD derived from crosses between AABB and DD) and Triticale(X.Triticosecale rimpaui Wittm,2n=6X=42,AABBRR),respectively.F_1 progeny plants had two to seven plant phenotypes in each cross combination and up to seven characters were segregating in F_1 generation.For example,chaff color varied greatly among F_1 plants,which suggests there were several genes that control wheat chaff color in these crosses.In addition,the average seed set of the F_2 plants was significantly higher compared with the seed set of F_1 plants.
