Embryo Development in Nicotiana Species Hybrids.
I n a study of the compatibilities of certain Nicotiana species, several crosses were reported which produce seeds unable to germinate. (MCCRAY 1932). Many others are recorded in the literature on this genus. Some of these seeds are parthenocarpic; others have embryos not able to develop. In still other cases the hybrid germinates but is unable to carry on further. All degrees of vigor have bee...
متن کاملCHROMOSOME COUNTS IN SOME MOSSES OF IRAN
Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...
متن کاملFlower Variegation in Hybrids between NICOTIANA TABACUM and N. OTOPHORA.
HE fate of genes and chromosomes following interspecific gene transfer Tdeserves detailed study. Genes of one species often can be introduced into another without evident changes of their action and with little effect upon their stability. ANDERSON'S (1949) widely known work on introgression after interspecific hybridization could not have been successful had he been dealing with unstable genet...
متن کاملSpontaneous morphological alterations of chromosomes in Nicotiana hybrids.
EVERAL workers have already reported that hybridization between Nicotiana species can bring about chromosome instability. One conspicuous case is loss of somatic plumbaginifolia chromosomes in derivatives of N . tabacum X N . plumbaginifolia hybrids (MOAV 1961). The present paper deals with another peculiarity of alien chromosomes in tobacco hybrid derivatives. It reports on heritable changes i...
متن کاملA Cytogenetic Study of Heritable Tumors in Nicotiana Species Hybrids.
ENETIC tumors in Nicotiana species hybrids have been reported by several Ginvestigators. These tumors are formed in certain specific hybrid combinations on stems, roots, and occasionally on leaves of all or part of the F, progeny. Since the discovery by KOSTOFF (1930) of nine interspecific tumorous hybrids, almost 20 additional hybrid combinations have been reported in which the entire progeny ...
