Item Screening of cowpea varieties for resistance to brown blotch fungal disease(2006) Ajibade, S. R.; Owolade, O. F.; Balogun, M. O.; Fadare, T. A.Seventy-one cowpea varieties were screened in the field out of which nine resistant varieties were selected and these were further evaluated for resistance to cowpea brown blotch disease caused by Collectorichnm capsicl under artificial inoculation. The results showed that the cowpea variety IT95k- 193-12 appeared to be the most resistant to brown blotch disease. Artificial inoculation seemed to be more effective in identifying resistant genotypes as most of the cowpea varieties with moderate resistance in the field were highly susceptible under artificial inoculation.Item Sex differences in biochemical contents of telfaira occidentalis hook F.(WFL Publishers, 2006) Ajibade, S. R.; Balogun, M. O.; Afolabi, O. O.; Kupolati, M. D.In order to evolve ways of early sex identification in Telfairia, the biochemical contents of leaf, vine and root of male and female plants were determined in three genotypes. Female plants had significantly higher concentrations of protein and fat while the male plant was higher in fibre, as hand all the anti-nutrients. The concentration of trypsin inhibitor was most influential in distinguishing between the sexes especially for root and vines while the fibre content was most important for the leaf. Leaf fibre content is therefore recommended for sex identification since it can be easily determined at any stage of plant development without destroying the whole plant.Item Genetic variation in nutritive and anti-nutritive contents of African yam bean (sphenostylis stenocarpa)(Wiley InterScience, 2005) Ajibade, S. R.; Balogun, M. O.; Afolabi, O. O.; Ajomale, K. O.; Fasoyiro, S. B.Seeds of 20 African yam bean collections were evaluated for nutritive and antinutritive contents. Anti-nutrients were negatively correlated with protein and carbohydrate contents. Principal component analysis and the Fastclus procedure showed that collections with high anti-nutrient contents had darker seed colour.Item Microproagation of fluted pumkin by enhanced axilary shoot formation(2002-05) Balogun, M. O.; Ajibade, S. R.; Ogunbodede, B. A.In a bid to develop protocols for micropropagation of fluted pumkin (Telfairia occidentalis), single node cuttings of two genotypes, Telfairia occidentalis white and Telfairia occidentalis orange (ToW-1 and ToR-1 respectively) were cuItured in Murashige and Skoog medium but with four different combinations of kinetin and naphthalene acetic acid concentrations. The highest number of nodes per plantlet was obtained in the medium containing l=litre2.0mg/l kinetin which indicates suitability for micropropagation purposes. There was however, lack of root formation: Premature senescence was also significantly predminant in ToR-1 relative to ToW1. Optimum medium for Telfairia micropropagation appears to be genotype
