[Genetic control of the isocitrate dehydrogenase and shikimate dehydrogenase isoenzyme systems in Sesame (Sesamun indicum L.)].
Taking into consideration that the ideal manipulation of isozymic markers needs knowledge of their genetic control, the aim of this study was to establish the inheritance and linkage degree of loci that control the expression of two sesame isozyme systems: isocitrate dehydrogenase (IDH) and shikimate dehydrogenase (SKD). The F2 electrophoretic behaviour of IDH and SKD from cultivars Turen x Arawaca cross was evaluated. The results suggest that IDH is controlled by two loci, Idh1 and Idh2 meanwhile SKD by only one, Skd1. The loci Idh1 and Skd1 showed three distinguishable patterns, corresponding to the homocygote genotypes and the heterocygote one, adjusted to a one-character common mendelian segregation 1:2:1. Cosegregation between Idh1 and Skd1 was independent.
