【摘要】 本文应用Giemsa C显带技术,对小黑麦异附加系材料进行了分析鉴定,从中鉴定出附加有黑麦染色体7R的二体异附加系;附加有1R、4R、6R和7R的单体异附加系;附加1R、6R和7R的单端双体异附加系;附加1R短臂(1RS)和6R短臂(6RS)的单端体异附加系。此外,还鉴定出附加4R和7R的单端体异附加系,但附加的端着丝点染色体是长臂还是短臂,尚未判明。更多还原

【Abstract】 Wheat-rye addition lines were identified by using Giemsa C-banding technique.From these lines,we obtained disomic addition of chromosome 7R,monosomic additions of chromosomes 1R,4R,6R and 7R,monotelodisomic additions of chromosomes 1R,6R and 7R,and mo-notelosomic additions of chromosomes IRS and 6RS.Although monotelosomic additions of chromosomes 4R and 7R were identified,it is uncertain whether their telochromosomes are short arms or long ones.更多还原
