To determine the true rate of aneuploidy and to elucidate the mechanism of aneuploidy,the sperms were decondensed for FISH analysis. It was found that the disomic frequencies of chromosome X was 0.208%. A new decondensation method was developed by trypsin treatment. The basic morphology of sperm was maintained.

为了解非整倍体的真实发生率及其发生机制,本文以X染色体α卫星DNA探针进一步检测出正常精子中X染色体的二体型频率为0.208%,同时,建立了一种保持精子基本形态的胰酶去凝聚的方法,为目前国内尚未开展的精子遗传物质结构的分子细胞遗传学研究,提供了新的手段。

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)。

Orientale additional and substitutional lines. chromosome number of 96 BC2 F3 individuals were accounted. Fifteen plants with 2n= 43 and eight plants with 2n= 44 were checked out. GISH results of the individuals with 43 chromosomes showed that they blonged to three different monosomic additions. Two disomic additions, ine double-monosomic addition, one trible- monosomic addition and one monosomic addition were found in the 2n = 44 individuals. One double-monosomic substitution and one monosomic sustitution were obtained.

为了筛选小麦-旱麦草异附加系、异代换系,对普通小麦品种Fukuho×东方旱麦草属间杂种的BC2F3代材料的96粒种子进行了染色体数目的检测,共检出15粒2n=43的种子,8粒2n=44的种子,进一步对以上材料进行的基因组DNA原位杂交,共鉴定出3个单体附加系,2个二体附加系,1个双单体附加,1个小麦三体单体附加,1个附加3条东方旱麦草染色体的小麦单体,在染色体数为42的个体中,检测出1个单体代换,1个双单体代换。

In the studies on transferring and identifying alien chro-mosomes into wheat,the combined use of mitotic and meioticchromosome N-banding is also successfully practiced in deter-mination of T.durum-H.villosa amphipoid,five wheatalien disomic additions with H.villosa chromosomes,〓〓,alien sulstitution line with chromosome 〓 andsome translocation lines.

在外源染色体导入、鉴定研究中,利用根尖有丝分裂中期染色体和花粉母细胞减数分裂中期Ⅰ染色体的N-分带,快速、准确地鉴定了硬粒小麦一簇毛麦双二倍体、普通小麦一簇毛麦异耐加系V〓、V〓、V〓、V〓和V〓,普通小麦一簇毛麦异代换系V〓以及一些具有易位的杂种后代。

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.

用基因组原位杂交(genomic in situ hybridization, GISH)结合双色荧光原位杂交(double-colour fluorescence in situ hybridization, dc-FISH)技术,对甘蓝型油菜新型恢复系Nsa恢1及其后代进行了研究,结果表明,Nsa恢1为甘蓝型油菜-新疆野生油菜二体异附加系,包含了甘蓝型油菜全基因组和新疆野生油菜1对染色体,这1对新疆野生油菜染色体为同源染色体。
