| The present paper was carried out to clear up the polyploidal constitution and the banding pattern of three species in tetraploidal Allium(X=8) through the studies of meiosis, karyotype and G-bands. From the meiotic data and G-banding patterns obtained under this study, it is confirmed that A. tuberosum and A. chinense are autotetraploids, and A. senescens is allotetraploid. Some aneuploids out of the employed species were found; A. senescens is 2n=34, and A. chinense is 2n=33. The chromosome types of these species are meta-and submetacentrics except the sat-chromosomes and the f-chromosomes. G-bands of these species are generally located in the end of each arm. A. senescens is similar in the quantity of heterochromatin with A. chinense, but A. tuberosum has a little than the other species. The quantity of heterochromatin is higher in small groups of chromosome than large ones, and higher in short arms than long arms. |
