Summary
This study was conducted to elucidate the inheritance and linkage relationships of isozymes in aspartate aminotransferase (AAT, EC 2.6.1.1), alcohol dehydrogenase (ADH, EC 1.1.1.1), phosphogluconate dehydrogenase (PGD, EC 1.1.1.43), phosphoglucomutase (PGM, EC 2.7.5.1) and shikimate dehydrogenase (SKDH, EC 1.1.1.25) in eggplant and its wild relatives. Segregating populations were generated by backcrossing of hybrids among the species. Evidence of Mendelian inheritance was obtained for seven loci: Aat-1, Adh-1, Adh-2, Pgd-1, Pgm-1, Pgm-2 and Skdh-1. Twenty-one pairs of loci were tested for independent assortment, suggesting three linked pairs, Aat-2 with Pgd-2 (R=0.35±0.07), Adh-2 with Pgm-1 (R=0.33±0.07) and Pgd-2 with Pgm-2 (R=0.32±0.06).
