Mark whether the following statements are true or false. (i) Entire collection of plants or seeds having all the diverse alleles for all genes in a given crop is called gene pool. (ii) A wide range of pathogens affect the yield of cultivated crop species, especially in tropical climates. (iii) High aspartic acid, low nitrogen and sugar content in maize lead to resistance to aphids. (iv) Biofortification is the most practical means to improve public health.

High aspartic acid,low nitrogen and sugar content in maize leads to resistance in maize against

High aspartic acid,low nitrogen and sugar content in maize leads to resistance in maize against

Assertion : high aspartic acid, high nitrogen and low sugar content in maize leads to resistance to maize stem borers. Reason : Smooth leaved and nectarless cotton varieties provide resistance from jassids.

Read of the following statements:- (a) Insect resistance in crop plants may be due to morphological, biochemical or physiological characteristics. (b) Hairy leaves in cotton are resistant to cereal jassids. (c) Smooth leaves and nectar-less cotton varieties do not attract bollworms. (d) In maize, high asparatic acids, low nitrogen and sugar leads to resistance to stemborers. Choose correct statements :-
