Q. Assertion: Tobacco hybrids produced from N. rustica and N. tabacum may exhibit resistance to blue mould. 

Reason: Blue mould resistance was a primary trait present in both parent lines and was intentionally selected for during the initial fusion process.

Q. Assertion: Symmetric hybrids are utilized to widen the genetic base of allopolyploid species.

 Reason: Producing synthetic lines of Brassica napus by fusing B. oleracea and B. campestris introduces desirable traits that might be missing in the current cultivated pool.

Q. Assertion: Somatic hybrids of potato fused with S. brevidens are used in breeding programs to combat Potato Leaf Roll Virus (PLRV). 

Reason:S. brevidens is a wild relative of the potato that carries natural resistance to certain viral and bacterial diseases like Erwinia soft rot.
