Identificación de progenies y progenitores por el análisis del número cromosómico en Saccharum

The chromosome numbers of Saccharum species were analyzed, and in some cases they were found to be consistent with previous reports. In other cases, a wider range of variation was found. In the study of simple hybrids, an ihtraclonal variation was found for C P. 36-138, and the self-fertilization...

description The chromosome numbers of Saccharum species were analyzed, and in some cases they were found to be consistent with previous reports. In other cases, a wider range of variation was found. In the study of simple hybrids, an ihtraclonal variation was found for C P. 36-138, and the self-fertilization of the same variety, My 53205, had a chromosome reduction typical of hybrid offspring. This produces a marked aneuploid in the Saccharun genus. In My 53205, the phenomenon of chromosome mosaic was also observed for a single bud similar to the case of clone 28 NG 201, reported under the S. edule species. The complex hybrids P. 0. J. 2878 and P. 0. J. 2725 had a range of variation similar to that of other references. Co. 281 had a very stable chromosome lumber. The intraclonal variation of these hybrids is minimum. Aneuploids and somatic instability should be evaluation factors in cytogenetic studies for clarifying the origin of hybrids obtained in plant breeding programs.
