Abstract:médio de flores por pseudobulbo é de 15, tendo sido observadas até 31 flores por pseudobulbo. UEL 6 apresenta flores com duração média de 20 dias, perío-do superior ao Dendrobium nobile selvagem, conhecido como "olho-de-boneca", cujas flores têm duração de onze dias.
MANUTENÇÃO E DISTRI-BUIÇÃO DE PLANTASPlantas da cultivar UEL 6 são mantidas pelo Depto. de Agronomia da UEL.

“…The diploid and tetraploid plants had flowers with an average duration of 11 days, which was the same duration of wild D. nobile flowers (Faria et al 2009). In this study, the tetraploid plants had greater flower heights (4.54%) and lip widths (18.46%) when compared to diploid flowers ( Figure 1 and Table 1).…”

“…The increased number of internodes (region between two nodes) proved to be a morphological variable that is economically viable because the orchid has lateral inflorescence starting on pseudobulb nodes forming several groups with two or three flowers each (Faria et al 2009). …”

“…The value of D. nobile depends on the sales of specific visual patterns transferred by genetic inheritance, such as color, size and shape of the flower. Breeding programs for Dendrobium aim at obtaining plants for the market with desirable characteristics, for example, pseudobulbs with high vigor, upright flowers, a large number of flowers and variability of colors and shapes as well as an extended flowering season (Faria et al 2009). In Brazil, however, there have been few studies on breeding orchids due to the long cycle of plants in the Dendrobium genus, which leads to an average flowering development of three to four years.…”

“…Faria et al (2009), Faria et al (2011), and Faria et al (2013, working with Dendrobium crosses, were successful in obtaining three new cultivars (UEL 6, UEL 7 and UEL 8), which expressed the desired characteristics of mother plants such as flower size, flower coloration, flourishing period, number of flowers, plant height, among others. also obtained a hybrid of Oncidiuns which, besides presenting desirable agronomic characteristics for a hybrid, gave more balance and symmetry to the flowers, between the floral whorls.…”
“…Currently, a program of genetic improvement of Dendrobium nobile has obtained superior cultivars in relation to growing conditions in Brazil (Faria et al, 2009).…”
Establishment of germplasm banks of ornamental species, together with breeding programs is fundamental for the growth of competitive cultivars of flowers that are the same or better quality than those developed in other countries. Around 100 progenies from a crossing between the cultivars Dendrobium 'Tong Chai Gold' and Dendrobium 'Black Jack' were obtained, from 50 plants which were selected and grown in pots in greenhouse conditions to evaluate the blooming stage and to select the progenies. Selection of vigorous growing plants and without disease symptoms were made in the period of cultivation. Also, there were evaluated the growing characteristics, rooting, early blooming, as well as the color, number and size of flowers in the first and second blooming. Six progenies with superior characteristics were chosen, from which Dendrobium 'Brazilian Fire 101' was obtained. This cultivar shows fast growth, good rooting, early flowering and high quality flowers, with predominantly yellow color, showing the ribs, the center of flowers and lip with red color. The durability of the flowers was 45-60 days after anthesis.
