摘要： Agropyron cristatum (2n=4x=28, PPPP) is a wild relative of common wheat which contains a large number of desirable genes that can be exploited for wheat improvement. Wheat-A. cristatum 2P alien translocation lines exhibit many desirable traits, such as small flag leaves, a high spikelet number and density, and a compact plant type. An agronomic trait evaluation and a genetic analysis were carried out on translocation lines and backcross populations of these lines carrying different translocation fragments. The results showed that a translocation fragment from 2PT-3 (2PL) reduced the length of the flag leaves, while translocation fragments from 2PT-3 (2PL) and 2PT-5 (2PL (0.60-1.00)) reduced the width of the flag leaves. A translocation fragment from 2PT-13 (2PS (0.18-0.36)) increased the length and area of the flag leaves. Translocation fragments from 2PT-3 (2PL) and 2PT-8 (2PL (0.86-1.00)) increased the density of spikelets. Translocation fragments from 2PT-7 (2PL (0.00-0.09)), 2PT-8 (2PL (0.86-1.00)), 2PT-10 (2PS), and 2PT-13 (2PS (0.18-0.36)) reduced plant height. This study provides a scientific basis for the effective utilization of wheat-A. cristatum translocation lines.
