Analysis of B-genome chromosome introgression in interspecific hybrids of Brassica napus × B. carinata.
Brassica carinata, an allotetraploid with B and C genomes, has a number of traits that would be valuable to introgress into B. napus. Interspecific hybrids were created between B. carinata (BBCC) and B. napus (AACC), using an advanced backcross approach to identify and introgress traits of agronomic interest from the B. carinata genome and to study the genetic changes that occur during the intr...
متن کاملCytogenetic and Molecular Characterization of B-Genome Introgression Lines of Brassica napus L.
Brassica napus introgression lines (ILs), having B-genome segments from B. carinata, were assessed genetically for extent of introgression and phenotypically for siliqua shatter resistance. Introgression lines had 7-9% higher DNA content, were meiotically stable, and had almost normal pollen fertility/seed set. Segment introgressions were confirmed by fluorescent genomic in situ hybridization (...
متن کاملPossibilities of direct introgression from Brassica napus to B. juncea and indirect introgression from B. napus to related Brassicaceae through B. juncea
The impact of genetically modified canola (Brassica napus) on biodiversity has been examined since its initial stage of commercialization. Various research groups have extensively investigated crossability and introgression among species of Brassicaceae. B. rapa and B. juncea are ranked first and second as the recipients of cross-pollination and introgression from B. napus, respectively. Crossa...
متن کاملMicrospore culture reveals high fitness of B. napus-like gametes in an interspecific hybrid between Brassica napus and B. oleracea
The strategies of crossing B. napus with parental species play important role in broadening and improving the genetic basis of B. napus by the introgression of genetic resources from parental species. With these strategies, it is easy to select new types of B. napus, but difficult to select new types of B. rapa or B. oleracea by self-pollination. This characteristic may be a consequence of high...
متن کاملVariability of Fatty Acid Composition in Interspecific Hybrids of Mustard Brassica Juncea and Brassica Napus
In Sri Lanka, mustard (Brassica juncea) is cultivated as a subsidiary crop for the seeds used as a condiment in cooking. In the Indian sub-continent, however, it is an important oilseed crop used as a source of vegetable oil. Mustard has over 45% erucic acid (C22:1) which is unsuitable nutritionally for human consumption. The Brassica oilseed species, B. napus and B. campestris, were developed ...
