Aneuploids of Pennisetum typhoides

抄録

Triploids of Pennisetum typhoides (2n=14) were isolated in the progeny of the cross between autotetraploid and normal diploid. The meiotic instability in the triploid resulted in the recovery of aneuploids in their progeny. Aneuploids having chromosome number ranging from 2n=15 to 19 were observed. Among the aneuploids, trisomics (2n+1=15) were the most frequent types. Pennisetum typhoides though basically a diploid high tolerance of extrachromosome has been observed in this study.
