There was also not any haploid metaphases (n=16 or 19) was detected in hybrids. However, about 1-2% metaphases observed in this study was allopolyploid. GISH proved that they was made up of haploid genomes of M. nobilis (n=16) and triploid genomes of C. farreri (n=57). GISH was also employed to detect different chromosome components and identify donor chromatin in hybrids between C. farreri♀×A.
但我们检测到了约1-2%异源多倍体的分裂相,GISH分析后发现这些分裂相是由单倍的华贵栉孔扇贝的染色体和多倍的栉孔扇贝染色体组成,比如论文中图示了一个异源四倍体的分裂相,它是由单倍的华贵栉孔扇贝的染色体(n=16)和三倍的栉孔扇贝染色体(3n=57)组成。

Up to date, QTL analysis of adult-plant resistance against powdery mildew has not been reported in China. In the present study, QTL mapping of APR was conducted using a doubled-haploid population derived from the cross (Fukuho-komugi × Oligoculm) and a F_(2:3) population from the cross (Bainong64 × Jingshuang16). The methods and main results are described as follows:1. A doubled-haploid population from an intervarietal cross between the Japannese cultivar Fukuho-kumugi and the Israeli wheat line Oligoculm was prouduced by means of wheat × maize crosses.
