【Abstract】 The increase of induction frequency of pollen callus from 0.39% to 4.14% was due to the following factors: genetic difference of the tested materials, the physiological state of the donor plants and the improvement in the cultural media and cultural methods.By analysis of the progeny genetics of the pollen plant, it was observed that the pollen plants derived from hybrid exhibited great diversity and wide separation, resulting in various recombination types which could be used as breeding materials. Stability was shown in H₂, H₃ and H₄, and no decrement of viability was observed.By selecting and identif ying the progeny of the pollen plant, a new wheat variety "Jinhua No. 1" has been developed. It has been shown that pollen haploid breeding is a new, economical and effective way in winter wheat breeding.更多还原
