摘要:

异附加系是重要的种间材料,可用于种间外源遗传物质的渐渗及基因定位等相关研究,创制多种类型的异附加系对于栽培黄瓜(Cucumis sativus)的品种改良及相关研究均具有重要作用。本试验中以来源于酸黄瓜(Cucumis hystrix)和栽培黄瓜‘北京截头’杂交的种间异源四倍体为母本,以‘北京截头’为轮回父本,连续回交获得22株植株。利用基因组荧光原位杂交(GISH)技术确定22株BC2群体中附加有外源染色体的植株,然后利用oligo-FISH技术和12个酸黄瓜染色体单拷贝序列标记准确识别外源染色体。共筛选出4种异附加系材料,包括3种单体异附加系和1种双单体异附加系。其中3种单体异附加系分别附加酸黄瓜6号、10号和12号染色体,双单体异附加系同时附加了酸黄瓜6号和10号染色体。

Abstract:

Alien addition lines are important interspecific materials,which can be used for introgression of interspecific genetic material and gene mapping. Creating a variety of alien addition lines plays an important role in cultivar improvement and related research of cucumber. In this experiment,based on the allotetraploid Cucumis hytivus from the cross of C. sativus and C. hystrix,two backcrosses with diploid cultivar C. sativus were carried out to obtain 22 plants of BC2. The plant containing alien chromosome in BC2 population was identified by GISH technique. Further,oligo-FISH technology and 12 C. hystrix chromosome specific single-copy sequence markers were used to accurately identify the alien chromosomes. Finally,a total of four different alien additional lines were screened,including three monosomic alien addition lines(MAALs)which contained C. hystrix chromosomes H06,H10,and H12,respectively,and one double alien monosomic addition line containing H06 and H10.

Key words: Cucumis sativus, Cucumis hystrix, alien addition line, oligo-FISH, single-copy sequence marker
