KARYOTYPE AND GIEMSA C-BANDING PATTERN OF PEA(Pisum sativum L.) |
| |
| Abstract: | Karyotype and Giemsa C-banding patterns of chromosomes in root tip cells (RTCs) of a pea variety "Ma-Huang-Zao" (Pisum sativum L.) have been studied in this experiment. Karyotype analysis shows that seven pairs of homologues of the pea variety can he distinguished morphologically. The results are lightly different from the normal type of Line 110 reported by Blixt (1958, 1959). By Giemsa C-banding technique, the characteristies of the C-banding patterns of chromosomes in RTCs of the pea variety hare been shown as follows: the secondary constriction bandings of chromosomes 4 and 7 are easily stainable and noticeable. Except chromosome 6, each of the other chromosomes shows a centromeric C-banding. The interstitial C-bandings are found in arms of chromosomes 4, 5, 6 and 7 |
