Quality aspects included were fruit colour as related to fruit firmness and contents of starch, sugar and acid. Fruit colour was strongly correlated with firmness and sugar content, whereas starch and acid content correlations were not consistent from green to intermediate and yellow fruit. Compared with 1996, yields were higher and the development of fruit colour poorer in 1997, probably caused by climatic variations. No correlations were found between ratings for tree density, tree vigour and tree openness vs. fruit colour, whereas crop load was highly correlated to both green, intermediate and yellow fruit colour, respectively. In addition, significant correlations were found between leaf N, leaf K, and fruit colour.

Round Leaf Yellow Yam (RLYY) after transfer to in vivo conditions, from day zero (day of transfer) to harvest of the first generation tubers at 314 d, and sprouting of these tubers. As the SNY and RLYY plants grew in vivo, abrupt changes occurred in the type of shoot (changed from type I to type II) and underground organ (from primary nodal complex to tuber), and in the rates of stem and root growth. Gradual changes occurred in the number of roots. The first observable morphological feature of the SNY and RLYY plants to change was the shoot tip.

Fruit composition was analysed for the concentrations of sucrose, reducing sugars, malic and citric acids in the flesh. The variability of growth and composition within each combination was high. The variation of composition was mainly related to the variation of growth during the second phase, although the fruit having largest diameters at thinning were often those with the highest citric acid concentration.

Miller, the third, sold as M. comosum `Epirus Giant', is a different species, possibly M. dionysicum Rech. fil. Therefore, the giant character on which this cultivar is sold is due possibly to a species trait rather than a giant genotype. Furthermore, while M. comosum `Plumosum' is a true genetic clone, the cultivar M. comosum is not, nor is `Epirus Giant'. Finally, we show that all the bulbs of the cultivar M. comosum are heterozygous for the inversion present in the second chromosome pair of this species.
