Evaluation of highland maize (Zea mays L.) cultivars for polyethylene glycol (PEG) induced moisture stress tolerance at germination and seedling growth stages

A laboratory experiment was performed at Ambo University, Department of Plant Sciences in March 2014, to evaluate the effect of moisture stress on germination and seedling growths of highland maize cultivars. The experiment was arranged factorially in completely randomized design with three replications. Five highland maize cultivars (Hora, Wenchi, Jibat, Argene and Wabi) were exposed to six levels of water stress (0,...

Combining ability studies of pigeonpea cytoplasmic male sterile (CMS) lines with an obcordate leaf marker

Hybrid pigeonpea [Cajanus cajan (L.) Millsp.] breeding technology based on cytoplasmic male sterile (CMS) was recently developed in India. A program was initiated to track the purity of female parental lines by incorporating an obcordate leaf shape marker in established male sterile A-lines. Seven obcordate A-lines developed by backcrossing and selection were crossed with four known fertility restorers in line x tester...
