【 摘 要 】

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.
