In vitro selection and characterization of salinity tolerant somaclones of tropical maize (Zea mays L.)
(2014-05-12)
Tolerance to salinity was obtained in an open pollinated variety (KAT) widely grown in the East African region and a dryland hybrid (PH01) by applying in vitro selection and regeneration procedures. Immature zygotic embryos ...
Efficacy of transgenic kernels harbouring the cry3a gene from bacillus thuringiensis in the control of the larger grain borer and maize weevil
(2012)
Insect bioassays were conducted to evaluate the efficacy of maize seed kernels expressing protein of aδ-endotoxin gene of Bacillus thuringiensis tenebrionis Cry3A against economically important coleopteran pests in stored ...
Regeneration and transformation potential of elite Kenyan highland maize inbred lines
(2010)
Agrobacterium-mediated transformation of tropical maize has been manipulated in only a limited number of genotypes, because a majority of maize germplasm isrecalcitrant toin vitroresponse. Establishment of a highly efficiency ...
Prospecting for bacillus thuringiensis for the control of prostephanus truncatus (horn) and sitophilus zeamais motschulsky
(2010)
Three hundred twenty nine samples from different parts of Kenya which had not previously been treated with bio-pesticide were collected for Bacillus thuringiensis isolation. The δ-endotoxin crystals were isolated from ...
Optimisation of parameters for agrobacterium-mediated transformation of sweet potato
(2010)
An Agrobacterium-mediated transformation and somatic regeneration protocol was adapted for a Kenyan sweet potato variety, KSP36. A model cultivar, CTP560 was used as a control. For selection of transformed explants paramomycin ...
Genotype independent somatic embryogenesis and plant regeneration from immature zygotic embryos of tropical maize inbred lines
(2012)
Maize is one of the most important cereal crops in Sub-Saharan Africa and an important source of energy for humans. However, the difference in the dedifferentiation frequency of immature embryos among various genotypes ...
Effect of 2, 4-d levels on callus induction of leaf and stem explants of 5 local farmer-preferred sweet potato varieties in Kenya
(2010)
Five local and popular sweet potato (Ipomoea batatas(Lam.) varieties were selected from the major sweet potato growing areas, based on farmer-preferences and desirable characteristics. Both leaf and stem explants were ...
