    Quality Evaluation of Fruit of a Range of Apple Cultivars/ Clones Grown in Ireland
    Overall quality of 20 apple cultivars/clones grown in Ireland was evaluated based on husbandry factors and fruit composition, colour, texture, flavour and aroma. Samples were tested on 7 occasions over a period of 4 seasons. Results showed that fruit of the cultivars/clones Golden Delicious, GD Smoothee, Crispin, Gala and GDC 446 was of good overall quality; that of Gloster 69, Idared, GD 88, GD 85, GD Stark, Karmijn and Moss's Seedling was intermediate while fruit of Jonathan, Kent, Suntan, Ivette, Sinta, GD 4E-23-10, Goldjon and GD Stark was of poor overall quality. The data show that fruit of Golden Delicious and its clones is well represented in the 'good overall quality' category.

    The Effects of Soil Management Systems on the Chemical Composition and Quality of Golden Delicious and Cox's Orange Pippin Apples- A Follow-up Study
    Tests on Golden Delicious and Cox's Orange Pippin apples, evaluated in five and three seasons, respectively, between 1972 and 1980, indicated that method of soil management was still influencing fruit quality 15 years after commencement of the experiment, although to a lesser extent than in the earlier years. In 1973, the soluble solids content, skin colour and yield values of Golden Delicious differed between treatments but no differences were observed for fruit firmness in any of the five seasons when fruit were tested. Acidity values differed in 1972, 1973 and 1980. Overall herbicides gave the highest yields in 1973 and 1975 and the lowest levels of soluble solids. The yield of Cox's Orange Pippin fruit varied considerably between seasons; yields between treatments within seasons were only different in 1975. Correlation coefficients between yield and soluble solids were negative and ranged from -0.51 to -0.68.

    The Effects of Soil Management Systems on the Chemical Composition and Quality of Apples II. Cox's Orange Pippin and Red Jonathan Apples
    The quality of fruit of Cox's Orange Pippin and Red Jonathan from different soil management treatments was tested in 1969 and again in 1970. The range of tests included soluble solids, reducing sugar and acid contents, texture measurements and taste panel assessment. The non-cultivation treatment gave the highest yields and the quality of fruit of both cultivars from all treatments was acceptable. Grass improved the quality of Cox's Orange Pippin in 1969 but not in 1970. Cultivation gave higher soluble solids levels than non-cultivation for Red Jonathan in both seasons. There was no correlation between soluble solids content and taste panel response for either cultivar. However, solids levels of fruit from the different treatments tested were close together thus making it difficult for the panel to distinguish between samples. Soluble solids levels increased in fruit of Cox's Orange Pippin during storage at 1°C in 1969 but remained constant in 1970. Levels in Red Jonathan decreased in both seasons. Fruit of Cox's Orange Pippin became softer during storage in both seasons while fruit of Red Jonathan softened only in 1969. Acid levels for fruit of both cultivars from the different soil management treatments were not significantly different in either season.
