C-banding analysis of eight species of Kengyilia Poaceae: Triticeae)

Jian Zeng, Gang Cao, Jing Liu, Hai-Qin Zhang, Yong-Hong Zhou


Abstract: To characterize chromosomes and the interspecific relationships within the genus Kengyilia, 8 species were used for Giemsa C-banding analysis. Results indicated that the species differed in C-banding patterns. K. gobicola, K. alatavica and K. batalinii had distinct centromeric bands and no banded chromosomes, while K. hirsuta, K. longiglumis, K. melanthera, K. rigidula and K. thoroldiana had more abundant and diagnostic C-bands with interstitial and terminal bands.

Key words: C-banding, chromosome morfology, genome, Kengyilia Karyotype, Triticeae.
