Vedclass · Answer

(A) Breeding for disease resistance is primarily carried out using conventional breeding techniques or mutation breeding.$1$. Conventional breeding techniques involve hybridization and selection to introduce resistance genes into crop varieties.$2$. Mutation breeding is the process of inducing mutations artificially using physical agents (like gamma radiation) or chemical agents (like ethyl methanesulfonate) to create genetic variation.$3$. Radiation breeding is a specific type of mutation breeding where radiation is used as the mutagen. Therefore,$II$ and $III$ are essentially the same category of breeding method.Since the question asks for the methods,both conventional breeding $(I)$ and mutation breeding ($II$ and $III$) are valid approaches. However,in standard textbook contexts,$I$ and $II$ are often cited as the primary categories. Given the options provided,$I$ and $II$ is the most appropriate choice.

Column-$I$	Column-$II$
$(1)$ Wheat	$(p)$ Taichung Native-$1$
$(2)$ Rice	$(q)$ Sonalika and Kalyan Sona
$(3)$ Sugarcane	$(r)$ Hybrid maize,jowar and bajra
$(4)$ Millets	$(s)$ Saccharum officinarum

Methods of breeding for acquiring disease resistance are:
$I$. Conventional breeding techniques
$II$. Mutation breeding
$III$. Radiation breeding
Choose the correct option.
