Interspecific hybridization in Brassica juncea and Brassica tournefortii through embryo rescue and their evaluation for biotic and abiotic stress tolerance.
Interspecific hybrids were obtained in an otherwise incompatible cross Brassica juncea x Brassica tournefortii through in vitro culture of hybrid embryos. The best response was observed from culture of embryos excised 20 days after pollination on MS medium supplemented with kinetin, alpha-naphthylacetic acid, gibberellic acid, glutamine and casein hydrolysate. One hybrid plant had many distinct...
متن کاملProduction of high yield short duration Brassica napus by interspecific hybridization between B. oleracea and B. rapa
Brassica napus is a leading oilseed crop throughout many parts of the world. It is well adapted to long day photoperiods, however, it does not adapt well to short day subtropical regions. Short duration B. napus plants were resynthesized through ovary culture from interspecific crosses in which B. rapa cultivars were reciprocally crossed with B. oleracea. From five different combinations, 17 hy...
متن کاملIsolation and Functional Characterization of a Floral Repressor, BcMAF1, From Pak-choi (Brassica rapa ssp. Chinensis)
MADS-box genes form a large gene family in plants and are involved in multiple biological processes, such as flowering. However, the regulation mechanism of MADS-box genes in flowering remains unresolved, especially under short-term cold conditions. In the present study, we isolated BcMAF1, a Pak-choi (Brassica rapa ssp. Chinensis) MADS AFFECTING FLOWERING (MAF), as a floral repressor and funct...
متن کاملProtoplast Culture and Fusion between Brassica Carinata and Brassica Napus
In this study, attempts were made to select in vitro responsible genotypes and to fuse the isolated protoplasts of Brassica carinata and Brassica napus breeding lines (BC DH Dodolla, BC DH -1, BC DH-6 and BN OP-1, BN-SL03/04), obtained from our previous experiments. Combination of three different PEG concentrations (20%, 25% or 30%) and two different treatment durations (15 and 20 min.) were te...
متن کاملCytogenetic Diversity of Simple Sequences Repeats in Morphotypes of Brassica rapa ssp. chinensis
A significant fraction of the nuclear DNA of all eukaryotes is comprised of simple sequence repeats (SSRs). Although these sequences are widely used for studying genetic variation, linkage mapping and evolution, little attention had been paid to the chromosomal distribution and cytogenetic diversity of these sequences. In this paper, we report the distribution characterization of mono-, di-, an...
