Studies on sequence changes in the early genomes of interspecific F_1 hybrid and amphidiploid in CucumisIn the present study,extensive genomic changes were detected in newly obtained allotetraploid of Cucumis,namely Cucumis hytivus Chen and Kirkbride,by AFLP analysis using 12 pairs of EcoR-I/Mse-I primers.

The result suggested that different genomes had different genetic speed or stability during evolution.3 The similarities co-efficiency between wild emmer and hexaploid synthetic was higher than that between wild emmer and common wheat. So that crossing among species is not a simple combination of genomes, but involve introgression of chromosomes, and the evolution made by this action was bigger than that made by environment.4 According to the results of salt tolerance identification, the salt tolerance of wild emmer is lower than that of common wheat in the whole.

野生二粒小麦与普通小麦之间的遗传相似系数稍高于野生二粒小麦与其与节节麦合成的双二倍体的遗传相似系数，说明物种之间的杂交并不仅仅是染色体组简单的合并，其中包括复杂的染色体组本身的一些特性以及染色体之间的互渗且这种作用远大于环境作用所引起的变化。

However, the use of Aegliops tauschii in improvement of wheat yield trait has not been reported. In this study, T.durum-Ae.Squarrosa amphidiploids was crossed with common wheat PH85-16, then backcrossed with PH85-16. The variation characteristic of the main yield traits of BC1F1 and BC1F2 were analyzed. Then, QTLs affecting yield traits were detected by 130 SSR primer pairs of D genome in BC_1F_1 and BC_1F_2.The result showed chromosomes in D genome from Aegliops tauschii affected yield trait of wheat significantly.
