• A. (iii) and (iv) only
• B. (i), (ii) and (iii)
• C. (ii), (iii) and (iv)
• D. (i) and (iii) only

Answer 1

The correct option is C (ii), (iii) and (iv)

Above given diagrams are of Indian crop varieties. The development of several high yielding varieties of wheat and rice in the mid-1960s, as a result of various plant breeding techniques led to dramatic increase in food production in our country. This phase is often referred to as the Green Revolution.

(a)Rice-Semi-dwarf rice varieties were derived from IR-8, (developed at International Rice Research Institute (IRRI), Philippines) and Taichung Native-1 (from Taiwan). The derivatives were introduced in 1966. Later better-yielding semi dwarf varieties Jaya and Ratna were developed in India.

(b)wheat-In 1963, several varieties such as Sonalika and Kalyan Sona, which were high yielding and disease resistant, were introduced all over the wheat-growing belt of India.

(c) Garden peas-he Indian Agricultural Research Institute, New Delhi has also released several vegetable crops that are rich in vitamins and minerals, e.g. protein enriched beans – broad, lablab, French and garden peas
