  1. A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field experiment was conducted on a Normandien clay loam (Plinthic Paleudult) to compare the acid tolerance of 48 commercially grown maize (Zea mays L.) cultivars. Cultivars were compared in terms of grain yield, plant height and leaf Al content...
  2. The nature of genotype × environment interactions for yield in wheat extension trials in the Winter Rainfall Region

    The nature of genotype × environment interactions for yield in wheat extension trials in the Winter Rainfall Region

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The necessity to subdivide the wheat producing soils of the Winter Rainfall Region for extension purposes, was considered. Use was made of correlations, interaction variance components and pattern analysis procedures to reflect on the possible existence of sub-environments with different...
  3. 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...
  4. 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...
  5. Comparison of cotton (<em>Gossypium hirsutum</em> L.) yield and fibre properties over locations and seasons

    Comparison of cotton (<em>Gossypium hirsutum</em> L.) yield and fibre properties over locations and seasons

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The cotton breeding program in the Republic of South Africa is conducted at the localities Loskop, Upington and Vaalharts. Preliminary results from breeding trials indicated that a finer but more mature fibre could be produced at Vaalharts as compared to...
  6. Multivariate assessment of environmental effects on hard red winter wheat. I. Principal-components analysis of yield and bread-making characteristics

    Multivariate assessment of environmental effects on hard red winter wheat. I. Principal-components analysis of yield and bread-making characteristics

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The attributes of yield and bread-making quality of winter wheats produced in the Free State are subject to environmental effects. The result is a supply to the baking industry of flour of inconsistent quality, which in turn is detrimental to...
  7. Multivariate assessment of environmental effects on hard red winter wheat. II. Canonical correlation and canonical variate analysis of yield, biochemical and bread-making characteristics

    Multivariate assessment of environmental effects on hard red winter wheat. II. Canonical correlation and canonical variate analysis of yield, biochemical and bread-making characteristics

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The inconsistent production of winter wheat with acceptable bread-making quality in the Free State reduces the commercial value of the wheat crop. In the second part of this study, canonical correlation analysis was used to determine to what extent variation...
  8. Determination of the preharvest sprouting resistance of South African winter wheat (<em>Triticum aestivum</em> L.) cultivars

    Determination of the preharvest sprouting resistance of South African winter wheat (<em>Triticum aestivum</em> L.) cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Preharvest sprouting significantly reduces the quality of the South African wheat crop. This study classified the preharvest sprouting resistance of 17 South African winter wheat cultivars sampled over a range of typical winter wheat growth environments. Sampling was performed under...
  9. Sources of variation for yield, protein content and hectolitre mass of spring wheat (<em>Triticum aestivum</em> L.) cultivars of the Western and Southern Cape

    Sources of variation for yield, protein content and hectolitre mass of spring wheat (<em>Triticum aestivum</em> L.) cultivars of the Western and Southern Cape

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In the Western and Southern Cape the quality of wheat varies annually due to variable climatic conditions. This holds a commercial risk to the milling and baking industries in delivering the refined products to their respective clients. It is, therefore,...
  10. 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...
