Cytological investigations of the interspecific hybrids of Nicotiana tabacum L. x N. glauca Grah.
Interspecific amphihaploid and amphidiploid hybrids between Nicotiana glauca Grah. (2n = 24) and N. tabacum L. (2n = 48) cultivars BY 103 and K 326 were analysed. F1 amphihaploids (2n = 36) were viable and completely self- and cross-sterile, and mostly univalents were present during meiosis (with pairing range from 0 to 5). In some meiocytes, meiotic irregularities were observed, such as sporad...
متن کاملInterspecific Crossing between Yam Species (Dioscorea rotundata and Dioscorea bulbifera) through in Vitro Ovule Culture
In the present study, in vitro ovule culture technique was used to obtain interspecific cross combination of Dioscorea rotundata ufenyi and Dioscorea bulbifera wild. Ten days after pollination, ovules were excised and cultured onto 1/2 strength Murashige and Skoog (MS) medium (Basal salt mixture + Vitamins) supplemented with 6% sucrose, 0.7% agar and plant growth hormones such as GA3, BAP, Picr...
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 کاملProduction of genetically male tilapia through interspecific hybridization between Oreochromis niloticus and O. aureus
This study was conducted to produce a high percentage of genetically male tilapia through interspecific hybridization between Nile tilapia, Oreochromis niloticus and Blue tilapia, O. aureus and evaluate sex ratio, productive performance and heterosis of the progeny produced. The results revealed that sex ratios of the progenies of (♀ O. aureus x ♂ O. niloticus) and (♀ O. niloticus x ♂ O. aureus...
