This paper gives the results of breeding system and cytological investigations on Cenchrus ciliaris L. a grass of District Rawalakot, Azad Kashmir-Pakistan. It is confirmed that Cenchrus ciliaris is apomict, probably a facultative apomict.
The meiotic results indicated that the chromosome pairing of this species was somewhat irregular, showing multivalents at metaphase I of meiosis. Cenchrus ciliaris is suggested to be allotetraploid with 2n = 34. The chromosome number 2n = 34 of this ecotype from Azad Kashmir-Pakistan, could be derived from 2n = 36, by the loss of a single pair of chromosome. It is concluded that all meiotic irregularities are indirectly associated with the apomictic phenomena of reproduction.
