Multivariate assessment of the agromorphological variability and yield components among sweet potato (Ipomoea batatas (L.) Lam) landraces

February 2011

Understanding the nature and magnitude of variability existing among sweetpotato genetic materials for important traits is vital for the effective utilization of such materials for breeding purposes. Eighteen landraces from diverse origins, plus three released cultivars as checks, were evaluated in two contrasting locations, using nine agronomic and eight morphological traits of the crop, to estimate the nature and...

Farm yard manure reduces the virulence of Alectra vogelii (Benth) on cowpea (Vigna unguiculata)

February 2011

The average productivity of cowpea in arid and semi-arid regions of Kenya is low due to a complex of biotic and abiotic stresses. Among the major biotic factors is the parasitic weed Alectra vogelii. Six cowpea varieties were evaluated in 2010 to determine the effect of farm yard manure on A. vogelii on six cowpea genotypes. Treatments consist of three tolerant (Kib-18, Kir/Nya-005 and Sia/Cia-004) and...

  Leaf segments of Stevia were cultured on MS medium supplemented with varying concentrations (0.5, 1.0, 1.5, 2.0, 2.5 mg/L-1) of growth regulators (BAP and 2, 4-D). Ninety one percent aseptic cultures were obtained when sterilized with 0.1% HgCl2 for 10 min. The highest amount of callus was obtained in MS medium supplemented with1.0 mg/L-1 BAP+0.5 mg/L-1 2, 4-D, respectively. On the...
