  1. Usage of antibiotics in the intensive care units of an academic tertiary-level hospital

    Usage of antibiotics in the intensive care units of an academic tertiary-level hospital

    Item type: Journal Article • Journal: Southern African Journal of Infectious Diseases
    Background: The post-antibiotic era is approaching fast as multidrug-resistant bacteria emerge and the antibiotic pipeline slows to a trickle. Antibiotic stewardship requires that antibiotics be used appropriately and as such this study reviewed the utilisation of antibiotics in five adult...
  2. Genotipe × omgewingsinteraksie by winterkoring in die Oranje-Vrystaat

    Genotipe × omgewingsinteraksie by winterkoring in die Oranje-Vrystaat

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Gesamentlike variansieanalises is uitgevoer op opbrengs, hektolitermassa en proteïeninhoud data verkry uit koring-evaluasieproewe wat in die Oranje-Vrystaat gedoen is. Die gebalanseerde datastelle het sewe winterkoringgenotipes, ingesluit wat op elk van 14 lokaliteite oor 'n periode van drie jaar geplant was...
  3. Genotipe—omgewingsinteraksie by sojabone

    Genotipe—omgewingsinteraksie by sojabone

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    'n Gekombineerde variansie-ontleding is uitgevoer op die saadopbrengste en proteïenpersentasies van die saad van 14 sojaboonkultivars wat op nege verskillende lokaliteite oor 3 jaar geëvalueer is. Variansiekomponente geassosieer met elke bron van variasie is beraam. Die verkreë resultate en implikasies...
  4. Combining ability effects of some spring wheat cultivars at two different temperature levels

    Combining ability effects of some spring wheat cultivars at two different temperature levels

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Yield losses due to high temperatures in the wheat growing season is a serious problem in South Africa. The aim of this study was to determine how the expression of general combining ability (GCA) and specific combining ability (SCA) was...
  5. Inheritance of resistance to Russian wheat aphid, <em>Diuraphis noxia</em> (Homoptera: Aphididae) in two wheat lines

    Inheritance of resistance to Russian wheat aphid, <em>Diuraphis noxia</em> (Homoptera: Aphididae) in two wheat lines

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The Russian wheat aphid, Diuraphis noxia, is a serious pest of wheat grown in the summer rainfall regions of South Africa. The use of D. noxia resistant cultivars may reduce the impact of this pest on cereal production, at the...
  6. Genotype × environment interaction of winter wheat (<em>Triticum aestivum L.</em>) in South Africa: I. AMMI analysis of yield performance

    Genotype × environment interaction of winter wheat (<em>Triticum aestivum L.</em>) in South Africa: I. AMMI analysis of yield performance

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirteen winter and intermediate type bread wheat cultivars were evaluated under dryland conditions over a four year period from 1991 to 1994 and over 120 environments in the Free State province of South Africa. The Additive Main Effects and Multiplicative...
  7. Genotype × environment interaction of winter wheat (<em>Triticum aestivum</em> L.) in South Africa: II. Stability analysis of yield performance

    Genotype × environment interaction of winter wheat (<em>Triticum aestivum</em> L.) in South Africa: II. Stability analysis of yield performance

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirteen winter and intermediate type bread wheat cultivars were evaluated for yield stability under dryland conditions over a four year period from 1991 to 1994 and over a total of 120 environments in the Western, Central and Eastern Free State...
  8. Breeding for resistance to ear rot of maize, caused by <em>Stenocarpella maydis</em> (Berk) Sutton. 1. Evaluation of selection criteria

    Breeding for resistance to ear rot of maize, caused by <em>Stenocarpella maydis</em> (Berk) Sutton. 1. Evaluation of selection criteria

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The objective of this study was to provide a better understanding of the interrelationship between methods of screening for resistance to ear rot, caused by Stenocarpella maydis. The inheritance of resistance as well as genetic and phenotypic correlation of various...
  9. Breeding for resistance to ear rot of maize, caused by <em>Stenocarpella maydis</em> (Berk) Sutton. 2. Inheritance of resistance

    Breeding for resistance to ear rot of maize, caused by <em>Stenocarpella maydis</em> (Berk) Sutton. 2. Inheritance of resistance

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The inheritance of resistance to ear rot, caused by Stenocarpella maydis, was investigated using a complete diallel cross of 10 inbred lines, ranging from resistant to susceptible. Parents, F1 crosses and reciprocals were evaluated at each of three localities, representative...
  10. New generation maize inbred lines resistant to diplodia ear rot, caused by <em>Stenocarpella maydis</em> (Berk) Sutton
