Abstract: Variant plants with red ligule and auricle were obtained by introduction of two rowed barley DNA into a common wheat Bainong 3217 with colourless ligule and auricle.The result showed that red character of ligule and auricle presented single gene heredity by observating the segragation of ligule and aurile colour in the generation of T 2,T 3 and F 2 of Bainong 3217×red auricle T4.It was also found that red auricle and ligule heredity in wheat (T.aestivum)is controlled by more than one pair of gene. The additive effect of quantitative gene had influence on the shade of the colour,and some environment facts such as thickness of sowing,low temperature could induce red auricle and ligule. The ratio oF3∶1 of red to colourlessness in ligule and auricle of wheat is a special case on the inheritance.
