  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. 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...
  6. 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...
  7. IETS OOR ASPEK: LINGOLOGIES GESIEN

    Item type: Journal Article • Journal: Taalfasette
  8. A comparison of HMW-GS, LMW-GS and RAPD fingerprinting for cultivar identification of some South African wheat cultivars

    A comparison of HMW-GS, LMW-GS and RAPD fingerprinting for cultivar identification of some South African wheat cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Accurate identification of breeding material is very important for the plant breeder. In South Africa, high molecular weight glutenin subunits (HMW-GS) have so far been used for wheat cultivar identification. This method can often not distinguish between cultivars, and other...
  9. 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...
