“…These authors commented that high CV's are expected because they are hybrid progenies with a great variability among descendents. According to According to Chan [6], pineapple cultivars are heterozygous and hybridization among them often leads to development of fertile seeds that contains a wide spectrum of genotypic combinations. From this segregating F1 population it is possible to select excellent individuals with trait recombinants within a progeny composed by numerous descendants.…”

“…Routinely, pineapple breeding programs generates and processes data bases with thousands of observations referring to dozens of traits related to the productivity and fruit quality, aiming to identify unexplored patterns or behaviors in this broad data set [3,6,7]. Knowledge about phenotypic variation of agronomic traits and diversity among genotypes based on dissimilarity coefficients can reveal useful information to guide breeding programs.…”

“…These studies are applicable to identify promising F1 individuals with wide divergence and higher mean for those traits related to the fruit quality and plant productivity. After this step these selected individuals can be used for cultivation per se and/or like a potential genitor in hybridization plans [6,7,13].…”

Knowledge about variation and relative importance of agronomic traits for genetic divergence studies can reveal useful information to guide the breeding programs. The objective of this study was to evaluate the phenotypic variation, and select of pineapple half-sib seedlings based on genetic divergence of fruit and plant traits. 'Pérola' cultivar (female genitor) received a pollen mix as from cultivars 'MD-2', 'BRS Imperial' and 'BRS Vitória' (male genitors). Four hundred twenty-nine F1 individuals propagated from seeds were evaluated under field conditions. Descriptive statistics, Singh's (1981) relative contribution, and Tocher's cluster optimization methods based on the distances matrix were estimated. Coefficients of variation ranged from 9.89 % to 63.79 %. Regarding total variance, fruit traits grouped 52.69%, while plant traits accumulated 47.30%. These results demonstrated that evaluated traits contribute for half-sib progeny relative discrimination and that none of them should be discarded for studies of diversity. Among the 12 heterotic clusters formed, group VII, IX and VIII are recommended to compose hybridization blocks and evaluation cycles of phenotypic stability for use per se. These groups have a broad heterotic potential, and desirable agronomic traits, mainly regarding to high means for fruit mass without crown (FMWC) upper than 4,000g and soluble solids content (SSC) around 20-21°Brix, which can be used by the IPA’s pineapple breeding program.

“…presents wide genetic diversity, mainly in Brazil, one of the centers of origin and dispersion of these Bromeliaceae (SOUZA et al, 2007;2012). This genetic variability, however, has been little explored yet, in spite of the potential of these plants to generate several products, mainly fibers for the manufacture of rustic material, such as ropes and fabric; the use in the automotive industry as a source of nanocellulose plastic, more resistant ho heat, gasoline and water and he envisions using it for dashboards, bumpers and body panels (LEÃO et al, 2009;MOHANTY et al, 2000;ZAH et al, 2007), manufacture of paper (MARQUES; GUTIÉRREZ; DEL RIO, 2007), proteolytic enzymes (MAURER, 2001) and secondary metabolites with antioxidant and biological activities of great value for the pharmaceutical, cosmetic and food industry (HARVEY, 2000;MANETTI;DELAPORTE;LAVERDE JUNIOR, 2009), besides its great ornamental potential (CHAN, 2006;COPPENS D'EECKENBRUGGE;DUVAL, 2009;DUVAL et al, 2001;SANEWSKI, 2009;SOUZA et al, 2007;2009).…”

-The use of pineapples as ornamental plants has increased in the last years due to their beauty and originality, demanding the generation of new varieties. The objective of the present work was to study the genetic variability and type of use of hybrids as ornamental pineapples, besides evaluating the resistance of these hybrids to Fusarium wilt. Six progenies, FRF-22 X FRF-1387, FRF-1392 X FRF-32, Curauá Roxo X Ananás Tricolor, G-44 X FRF-1387, FRF-1392 X FRF-224 and FRF-1387 X FRF-224, were evaluated by eleven morphological descriptors, and five categories of use were taken into account: landscaping plants, cut flower, potted plants, minifruits and foliage. High variability within and between progenies was detected, which allowed the selection of 16 hybrids as cut flowers, 17 as landscaping plants, four as minifruits, two as potted plants and just three as foliage. Fourteen of them were recorded for more than one type of use. For resistance to the Fusarium, out of the 31 hybrids evaluated, 11 presented resistance, 17 were moderately resistant and three were susceptible.Key words: Ananas sp.. Hybridization.

Phytosanitary RESUMO -O uso do abacaxi como planta ornamental vem se intensificando nos últimos anos, por sua beleza e originalidade e é crescente a demanda por novas variedades. O objetivo desse trabalho foi estudar a variabilidade genética em progênies de abacaxi ornamental, identificando as formas de uso e a resistência à fusariose dos híbridos selecionados. Foram aplicados onze descritores morfológicos em seis progênies: FRF-22 X FRF-1387, FRF-1392 X FRF-32, Curauá Roxo X Ananás Tricolor, G-44 X FRF-1387, FRF-1392 X FRF-224 e FRF-1387 X FRF-224, sendo os híbridos enquadrados nas categorias de paisagismo, corte, vaso, minifrutos e folhagens e cerca-viva. Em paralelo foi estudado a resistência a fusariose dos híbridos selecionados. Foi verificada grande variabilidade entre e dentro das progênies, permitindo selecionar 16 híbridos para flor de corte, 17 para paisagismo, quatro para minifrutos, dois para vasos e apenas três para folhagem, sendo 14 com mais de uma forma de uso. Dos 31 híbridos avaliados para a fusariose, 11 apresentaram resistência, 17 moderadamente resistente e três suscetíveis.Palavras-chave: Ananas sp.. Hibridação. Descritores morfológicos.

Wild Crop Relatives: Genomic and Breeding Resources

The pineapple, Ananas comosus var. comosus, a major contribution from Precolombian civilizations to world horticulture, evolved from the wild A. comosus var. ananassoides in the Guianas and further developed into a wide range of large-fruited cultivars in the upper Amazon, more than 3,500 thousands years ago, before diffusing to all tropical Americas in prehistoric times. As wild relatives and primitive cultigens belong to the botanical varieties of A. comosus and to the wild tetraploid A. macrodontes, reproductive barriers are inexistent or limited to differences in ploidy. The exploitation of wild and primitive germplasm is promising for pineapple breeding; however, it is limited by the difficult characterization and introgression of resistance traits. In comparison, the development of ornamental cultivars appears straightforward, as interesting traits are much easier to manipulate. Other uses, as high-quality fiber production and pharmaceutical treatments, open new commercial perspectives. Ananas germplasm collections clearly need further investigation to realize their full potential. (Résumé d'auteur
