Abstract
Combining ability and interrelationships among four characters were studied in six gooseberry (Ribes grossularia) progenies produced by crossing each of two thornless to three large-fruited cultivars. Measurements were recorded for four consecutive years for fruit yield and 100-berry weight, and for one year for thorniness and plant height. General and specific combining abilities were significant and their interactions with years were not significant for fruit yield and berry weight, and general combining ability was significant for thorniness. Genotypic correlations agreed closely with the phenotypic correlations. Significant positive correlations were obtained between fruit yield with berry weight and plant height. The nonsignificant correlations between thorniness with fruit yield, berry weight and plant height suggest no genetic barrier to combining thornlessness with these traits.
