杂交

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

Lines which were 2n=21"+1" and one line which was 2n=20"+2", one line which was 2n=43. The salt-resistance addition line Line15 was confirmed as a Disomic alien addition line by C-banding, SSR, FISH methods, and the two alien addition chromosomes had close correlation with the long arm of the second homoeologous group, the centromere region of the third homoeologous group and the short arm of the seventh homoeologous group. We also confirmed the particular C-banding type of the alien addition chromosomes by C-banding following FISH method. The drought-resistance addition line Line17 was found also as a Disomic alien addition line by SSR and FISH detection. The alien addition chromosomes had close correlation with the short arm of the second homoeologous group.

对导入赖草优质耐盐基因的株系Line15进行了C-分带、荧光原位杂交、SSR相结合的鉴定，确认Line15是一个二体异附加系，附加的一对染色体与小麦的第二同源群长臂、第三同源群着丝粒和第七同源群短臂密切相关，并确定了Line15的外源染色体C-分带特征带型，为目后鉴定Line15附加系的真伪提供了简便快捷的途径；对抗旱附加系Line17进行了荧光原位杂交和SSR检测，得出Line17也是一个二体异附加系，外源染色体与小麦的第四同源群短臂密切相关。

The barley chromosome in wheat was identified by genomic in situ hybridization in which biotin labelled total genomic DNA of barley betzes was used as probe and the unlabelled total DNA of common wheat Chinese Spring as blocking DNA. A series of wheat materials were tested as follows; two disomic alien substitution and monosomic alien addition lines, 2n=43; two monosomic alien substitution lines.

用生物素(Biotin-16-dUTP)标记的大麦Betzes基因组DNA作探针，以普通小麦中国春总DNA作封阻进行基因组原位杂交(Genome in situ hybridiz ation，简称GISH)，从13株小麦-大麦杂交后代中鉴定出2个含有3条大麦B etzes2H染色体的材料(2n=43)；2个2H单体异代换系(2n=42)；7个2H二体异代换系(2n=42)。

The novel restorer line Nsa restorer-1 and its progenies were analysed by genomic in situ hybridization combined with double-colour fluorescence in situ hybridization technologies, the results showed that Nsa restorer-1 was Brassica napus-Xinjiang wild Sinapis arvensis disomic alien addition line,consisting of the whole genome of Brassica napus and a homologous chromosome pair of Xinjiang wild Sinapis arvensis.
