Methods Amniocenteses were performed in 34 pregnant women of 16～23 gestational weeks with indications for prenatal diagnosis. The amniotic fluid samples were cultured in Chang's medium. The metaphase chromosomes were hybridized insitu with the human centromere probes,α-satellites DNA probes of X, Y,13, 21, 18 chromosomes and all primer chromosome probes. These probes were conjugated by Biotin and Dioxin then. The treated slides were examined and taken photos under the fluoromicroscope.

对34例孕16～23周有产前诊断指征者经腹部抽取羊水，用Chang培养液传代培养，常规制备羊水细胞分裂中期染色体，应用生物素及地高辛标记的人类全着丝粒探针和X、Y、13、21、18号染色体α-着丝粒探针及染色体全涂染探针，与培养的羊水细胞分裂中期染色体DNA进行原位杂交，杂交后用荧光显微镜观察玻片并摄像。

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.

本研究以二倍体小麦粗山羊草与四倍体硬粒小麦合成的双二倍体Am6为亲本，与普通小麦PH85-16 进行杂交，再用PH85-16 进行回交，对获得的回交后代进行了主要产量性状调查，利用位于小麦D 基组的SSR 分子标记进行了分子标记分析，对来自粗山羊草与产量性状相关的数量性状位点进行定位，探讨粗山羊草对小麦产量性状的影响。
