Vedclass · Answer

(D) Host crop plants can exhibit resistance to insect pests through various mechanisms,including morphological,biochemical,and physiological characteristics.$(i)$ Morphological characteristics: For example,hairy leaves in cotton provide resistance to jassids,and in wheat,they provide resistance to cereal leaf beetles.$(ii)$ Biochemical characteristics: For example,in maize,high aspartic acid content,low nitrogen,and low sugar content provide resistance against stem borers.$(iii)$ Physiological characteristics: Certain physiological traits can also influence the preference or survival of pests on the host plant.Therefore,all three factors ($I$,$II$,and $III$) contribute to the resistance of crop plants against insect pests.

List-$I$ (Crop Variety)	List-$II$ (Disease Resistance)

$(b)$ Pusa Komal	$(2)$ Black rot
$(c)$ Pusa Snowball $K-1$	$(3)$ Bacterial blight
$(d)$ Pusa Swarnim
	$(4)$ Hill bunt
