Embrapa Cassava and Fruits has developed ornamental pineapple hybrids for several categories of ornamental use including cut flowers, potted plants and landscaping. The objective of this study was to carry out a clonal evaluation of two ornamental hybrids using quantitative and qualitative morphological descriptors to recommend these hybrids as new ornamental pineapple cultivars. Twenty plants of each hybrid (PL01 and PL04) were evaluated regarding the response to floral induction as well as the stability and homogeneity of the clones in two production cycles. The descriptive statistics were calculated and analyzed to determine the genetic distance based on the Gower algorithm. Four groups were formed, two using parental data and the other two containing the different hybrids that were evaluated in the two growing cycles. In the floral evaluation, the time from field planting to harvest of the stem as a cut flower was determined to be as long as 17 months in the first cycle and 13.5 months in the second cycle for both hybrids. They were characterized as a novelty in the flower market; they showed genetic stability and homogeneity and can be recommended as new cultivars of ornamental pineapple because they exhibit satisfactory quality and meet the market requirements. |

The harvest of new segregating progenies made during the year 2008 was affected by excess of water in a plot that turned out to have deficient drainages. At the time of harvest, therefore, there were too many genotypes that had rotten roots. Nonetheless there was a group of eight genotypes that showed excellent levels of total carotenoids content (TCC) with an average above 13 mg.g-1 FW. Unfortunately logistic problems precluded the evaluation of these roots through HPLC on fresh samples but on frozen ones (-20 °C), which turned out to have obvious overestimations by a factor that cannot be assessed. These genotypes have been cloned and are being evaluated again during 2009. Average total carotenoids content (at 10 months of age) was 8.9 mg.g-1 FW and, when measured again at 12 months, levels had increased to an average of 13.5 mg.g-1
FW. This demonstrates again the effect of age in the accumulation of TCC and the need to take the age factor into consideration in further evaluations. Roots from genotype GM 1521-9 (MCOL2547 x MPER297), when harvested at eight months of age (March 2009), provided a TCC value of 14.3 mg.g-1 FW. It is expected that the same genotype arvested at 12 months of age (August 2009) will have significantly higher values. |
