Cabbage is an economically important vegetable worldwide. Cabbage Fusarium Wilt (CFW) is a destructive disease that results in considerable yield and quality losses in cole crops. The use of CFW-resistant varieties is the most effective strategy to mitigate the effects of CFW. 01-20 is an elite cabbage line with desirable traits and a high combining ability, but it is highly susceptible to CFW....

Cotton leaf curl virus disease (CLCuD) is an important constraint to cotton production. The resistance of G. arboreum to this devastating disease is well documented. In the present investigation, we explored the possibility of transferring genes for resistance to CLCuD from G. arboreum (2n = 26) cv 15-Mollisoni into G. hirsutum (2n = 52) cv CRSM-38 through conventional breeding. We investigated...

We show that there is a new mechanism for nonmonotonous behavior of magnetic field dependence of the electronic thermal conductivity κ of clean superconductors with nodes of the order parameter on the Fermi surface. In particular, for unitary scatterers the nonmonotony of relaxation time takes place. Contribution from the intervortex space turns out to be essential for this effect even at low t...

Plant architecture improvement is of great significance in influencing crop yield, harvesting efficiency and ornamental value, by changing the spatial structure canopy. However, mechanism on plant woody plants still unclear. In order to study genetic control traits promote marker-assisted selection (MAS), a linkage map was constructed, QTL mapping performed. this study, using 188 BC2 progenies ...

Major histocompatibility (B) complex haplotypes BQ and B17 were examined for their effect on Rous sarcoma outcome. Pedigree matings of BQB17 chickens from the second backcross generation (BC2) of Line UCD 001 (BQBQ) mated to Line UCD 003 (B17B17) produced progeny with genotypes BQBQ, BQB17, and B17B17. Sixweek-old chickens were injected with subgroup A Rous sarcoma virus (RSV). The tumors were ...

An application of DNA fingerprints (DFP) for gene introgression in breeding programs of both farm animals and plants is proposed. DFP loci, detectable by minisatellite probes, are extremely polymorphic. Individuals have unique patterns of DFP and thus can be selected for maximal genomic similarity to the recipient line, and minimal similarity to the donor line, using their DFP patterns as the c...
