EVALUATION OF AFRICAN EGGPLANT FOR YIELD AND QUALITY CHARACTERISTICS

M.O. Oluoch, M.L. Chadha
African eggplant is an important vegetable crop in sub-Saharan Africa but little research has been carried out to determine its yield and quality potential. Evaluation trials were carried out in Arusha, Tanzania from year 2002 to 2006 on three cultivated species (Solanum aethiopicum, S. macrocarpon and S. anguivi) to determine the yield and quality characteristics of selected lines collected from different countries in Africa. The experiments were laid out in RCBD with three replications. 42 lines were evaluated. Results showed five year mean fruit yields ranging from 1.3 t/ha to 62.5 t/ha with lines AB2, NA, N15, Manyire Green, OAA(089)N18, Heart shape, and N24 giving mean fruit yields of over 57 t/ha. The mean seed yields ranged from 94 to 2294 kg/ha with line L11-05 showing the highest seed yield of 112.72 g/plant and 2294.13 kg/ha, respectively. The lowest seed yield was observed with lines ex-mauritius and UVPP which gave yields of 3.5 and 6.28 g/plant respectively. Combined mean data for species comparison showed that S. aethiopicum lines gave significantly higher fruit yields (47.4 t/ha) than other species tested while S. anguivi lines gave significantly higher seed yields (1512 kg/ha). S. macrocarpon lines showed the lowest mean fruit and seed yields when compared to the other species. The Total Soluble Solids (TSS) content among selected lines varied from 4 to 12 with lines Tengeru white, Ex-Dar and DB3 giving TSS contents of over 10. Significant differences in fruit, seed yield and TSS content among the lines and species of African eggplant may help in identifying superior cultivars that can either be used to develop new varieties or directly disseminated to farmers and consumers in Africa for utilization.
