| Summary, etc. | Cytological and biochemical variations were studied to detect the variations between cytoplasmic male sterile (CMS) lines, their maintainer lines and two local cultivars of rice (Oryza sativa). The cytological behavior of the maintainer lines and local cuItivars was normal and showed 12 bivalents. CMS lines were found to exhibit tetravalent (metaphase I), lagging chromosomes (anaphase 1), and micronuclei (quartet). The presence of micronuclei in the CMS lines may be due to irregularity in the chromosomal behavior. The maintainer lines and the local cultivars revealed lower percentages of abortive pollen grains than that of the CMS lines, which showed percentages of sterility that ranged from 98.8% to 100%. This highly degree of sterility was due to the high percentage of chromosomal irregularities of the CMS lines, which, in tum, could reflect the role of the cytoplasm. The esterase and peroxidase analysis showed that there were differences between the CMS lines and maintainer lines in band number and band activity as well. The local cultivar Giza181 possessed the same number of bands as the CMS lines and maintainer lines. This result may be due to the fact that Giza lSI is related to the Indica subspecies as the case of the eMS lines and their maintainer lineS. |
