The cyto-morphological and chemical aspects of 3 F1 hybrids of crosses involving 3 cultivated brinjal varieties (Round Special, Round Mixed and Purple Long Datta) and one wild brinjal variety (S. malongena var. insanum) were studied. 2. All the 3 F1 hybrids showed a high degree of heterosis in many economically important characters like numberof branches, earliness, total number of flowers and total number of fruits per plant. 3. The F1 hybrids were intermediate in flower size, mean leaf area, percentage of fruit set, number of seeds per fruit and germination percentage of F2 seeds. 4. In fruit size of the F12 were approximating more to the geometric mean than arithmetic mean of the two parents.ennullThesis
