| Abstract: | The investigation aims at a comparative study of two kinds of F2 populations. The first one was derived from hybrids between two tetraploid parents, namely A-hypognea and A.sp (A.354) whose genomes are homologous. The second typeof tetraploids were derived from back cross hybrids between A-hypognea and allotriploid (resulting from the cross A-hypognea X A.sp. (A.329)). A comparative morphological and cytological analysis of these F2 populations have been made. Special techniques such as Hybrid index method and Polygraphic analysis were adopted and the variability expressed in the two F2populations have been eveluated. The possible causes for the occurrence of a skewed recombination in the straight F2 population have been suggested. |
