  A study was conducted to assess the influence of floral induction on the quality of pineapple (Ananas comosus) fruits. Freshly harvested pineapple fruits from farmers’ managed fields that were induced by calcium carbide and non-induced (control) from Ayensudo, a major pineapple producing center in the Central Region of Ghana. The fruits were chemically analysed in the laboratory. The results revealed that moisture content of chemically induced pineapple is lower (84.3%) than the non-induced fruits (86.8%). Total sugars, sucrose and reducing sugars were all higher in induced fruits than the non-induced fruits. Organoleptic analysis showed 88.9% of the consumer preference for chemically induced fruits. Chemical induced fruits have shorter shelf-life than non-induced fruits.

  Factorial mating design was used to generate twenty-five hybrids from five male sterile (A- lines) and five male fertile (R-lines) parents. Ten parents and twenty five hybrids were evaluated in a Randomised Complete Block Design replicated 3 times. Analysis of variance showed significant differences between crosses (male x female interaction) for plant height, 1000 seed weight and grain yield. High heterotic value of 692.03% for grain yield was recorded. Hybrids that exhibited high heterotic value for grain yield, likewise has high heterotic value for yield components; panicle length, panicle weight, 1000 seed weight and number of seed per panicle. Narrow sense heritability was low for seedling vigour, days to 50% bloom plant height, panicle weight, number of seed/panicle and grain yield. Moderate heritability was obtained for panicle length and 1000 seed weight, thus preponderance of non-additive gene action for all traits studied. The best all round hybrids identified from this study are MA10xNR 71143, MA10xNR71146, MA10xNR71167 and 2219AxNR71167.
