aprogenies from 13 artificial and six open-polinated intervarietal pineapple crosses were analyzed for leaf spininessand leaf color. A new hypothesis for the inheritance of the leaf spininess trait based on the observed segregations is put foward. It clearly explains the segregation of 11 out of the 13 artificial crosses, whereas the current accepted hypothesis (Collins nad Kernes, J. Heredity 37: 123-128, 1946) explains only eight of the 13 crosses. Three crosses were crucial for the acceptance or rejection of both hypotheses. The crosses Boituva x Smooth Cayenne and Perola x Smooth Cayenne, which involve "non-piping" and heterozygous for the S locus (Ss) parents, gave rise to spineless individuals in the offspring, at the expected frequency of three spinyto one spineless. This fact cannot be explained by Collins and Kernes'(1946) hypothesis. The cross Roxo-de-Tefe x Rondon resulted in nearly 100% spiny descendants, different from the frequency expected by the Collins and Kernes' hypothesis (50% spineless. |
