Genetic variability and correlation studies in the fluted pumpkin (Telfairia occidentalis Hook F.)

  Thirty-five genotypes of the fluted pumpkin (Telfairia occidentalis) collected from seven states in Southern Nigeria were evaluated for ten agronomic characters. The results obtained showed considerable variation among the genotypes for all characters studied. Low level of environmental influence was observed in the expression of all the characters studied except number of branches per plant and internode...

Combining ability of maize inbred lines resistant to Chilo partellus (Swinhoe) in the mid-altitude environment of Kenya

  Gene action conditioning important traits in maize is useful to breeders in order to design appropriate breeding methods. A study was conducted to determine the combining ability of 10 maize inbred lines adapted to Kenya’s mid-altitude environment and being resistant to spotted stem borer, Chilo partellus. The inbred lines were crossed in a diallel scheme and the resulting 45 single crosses...
