  1. Comparison of SSR and AFLP analysis for genetic diversity assessment of Ethiopian arabica coffee genotypes

    Comparison of SSR and AFLP analysis for genetic diversity assessment of Ethiopian arabica coffee genotypes

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Knowledge of genetic diversity within and among genotypes of any crop is fundamental for estimation of the potential genetic gain in a breeding programme and effective conservation of available genetic resources. Currently, different molecular marker techniques are being developed for...
  2. Agronomic performance of new cream to yellow-orange sweetpotato cultivars in diverse environments across South Africa

    Agronomic performance of new cream to yellow-orange sweetpotato cultivars in diverse environments across South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Sweetpotato is grown in diverse environments of South Africa by both commercial and subsistence farmers. The aim of the present study was to assess the stability, agronomic performance and palatability of new ARC cultivars bred for the informal market, and...
  3. Effect of heat stress on seed yield components and oil composition in high- and mid-oleic sunflower hybrids

    Effect of heat stress on seed yield components and oil composition in high- and mid-oleic sunflower hybrids

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    High temperature stress is a major environmental factor influencing processes such as growth, yield and quality of crops. The objective of this study was to assess the effect of heat stress, applied during grain-filling, on seed yield- and oil quality...
  4. Trends and magnitudes of genotype × environment interaction variance components for yield, quality and agronomic traits among coastal short cycle sugarcane breeding populations

    Trends and magnitudes of genotype × environment interaction variance components for yield, quality and agronomic traits among coastal short cycle sugarcane breeding populations

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Genotype × environment interactions (G×E) can reduce the genetic contribution to the phenotype and increase minimum detectable differences, which eventually reduce selection precision. This study was conducted to determine the magnitudes and trends of G×E variance components for sugarcane yield,...
  5. Location and crop-year effects on sugarcane genotype performance for the coastal short cycle breeding programmes in South Africa

    Location and crop-year effects on sugarcane genotype performance for the coastal short cycle breeding programmes in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Genotypes are tested in several environments to evaluate the influence of genotype × environment interactions prior to their release as cultivars. The objective of this study was to determine location and crop-year effects and their implications on coastal short cycle...
  6. Trends in broad-sense heritability and predicted selection gains for the coastal short cycle breeding sugarcane programmes in South Africa

    Trends in broad-sense heritability and predicted selection gains for the coastal short cycle breeding sugarcane programmes in South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Coastal short cycle breeding programmes develop early maturing sugarcane cultivars adapted to harvesting at 12 months under rainfed conditions. Genotypes progressed to the advanced cultivar stage from these programmes are merged and evaluated concurrently in multi-environment trials across the region...
  7. Allelopathic interaction between <em>Chenopodium album</em> L. and certain crop species

    Allelopathic interaction between <em>Chenopodium album</em> L. and certain crop species

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Laboratory and glasshouse studies were conducted to assess the allelopathic effect of Chenopodium album L. on the germination and early growth of certain crop species. Test species were grown in soils containing 1% (m/m) freeze-dried shoot material of the weed...
  8. The effect of chloride on four different citrus rootstocks

    The effect of chloride on four different citrus rootstocks

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Seedlings of Troyer citrange [Poncirus Mollata L. Raf. × Citrus sinensis L. Osbeck] (Tro), Citrus volkameriana (Vol), Carrizo citrange [Poncirus trifoliata L. Raf. × Citrus sinensis L. Osbeck], (Car) and Rough lemon [Citrus jambhiri Lush.] (Rie) were tested for tolerance...
