markers. This article reports the first breeding and validation of an interspecific hybrid between P. tomentosa and P. salicina . Materials and Methods Breeding process. The hybrid was selected from a group of seedlings from a controlled cross between
1990. Two interspecific F 1 s were obtained from the 66 fruit that set from this cross. The F 1 s were backcrossed to Fla. 7409 and a fair amount of seed was produced, but germination was less than 2%. The backcross to Fla. 7409 was advanced to the F 7
Dendrobium accessions from different species and hybrids; and 2) determine whether morphological, molecular, or combined analysis can discriminate Dendrobium species, Dendrobium commercial hybrids, and Dendrobium interspecific hybrids. Materials and
. Neither softwood cuttings nor root cuttings are successful, unless cutting wood is taken from very young seedlings. Thus, to make greenhouse crosses using superior wild plants from the forest, propagules must be taken that contain both roots and stems
introduction of the ‘Pamirskij 5’ resistance gene to peach powdery mildew in fruit cultivars. The Gr gene controlling red leaf color has been mapped to linkage group 6 both in a genetic map derived from an interspecific cross with GN22 ( Dirlewanger et al
base that included elite clones of Chilean germplasm that were horticulturally superior to the F. chiloensis previously studied; and 2) we performed a round of improvement within species before making the interspecific crosses to maximize levels of
controlling the trait. Pasqualini et al. (2006 ) did not find high levels of resistance in many selections from some interspecific crosses involving NY 10353 and NY 10355 and observed that transmission of resistance depended on the parental combination. They
, as in the case of T . parishii and T . lanatum populations, as well as T . ruygtii and T . lanceolatum . No intermediate hybrids have been reported for sect. Trichostema from field observations, even though interspecific hybridization
commercial cultivars. However, triploid plants have very low fertility, are generally sterile, and do not induce seeds in other cultivars by cross-pollination ( Frost and Soost, 1968 ). Several methods have been developed to obtain triploid citrus ( Navarro
