the three options that can be thought for increasing food production (i) agro-chemical based agriculture; (ii) ______ (iii) genetically engineered crop-based agriculture.
7 of 15
The Green Revolution succeeded in ______ the food supply but yet it was not enough to feed the growing human population
8 of 15
Increased yields have partly been due to the use of improved crop varieties, but mainly due to the use of better management practices and use of agrochemicals ( ______ and pesticides).
9 of 15
For farmers in the developing world, agrochemicals are often too expensive, and further increases in yield with existing varieties are not possible using ______ breeding.
10 of 15
As traditional breeding techniques failed to keep pace with demand and to provide sufficiently fast and efficient systems for crop improvement, another technology called ______ got developed.

It was learnt by scientists, during 1950s, that whole plants could be regenerated from ______, i.e., any part of a plant taken out and grown in a test tube, under sterile conditions in special nutrient media.
12 of 15
This capacity to generate a whole plant from any cell/explant is called ______ .
13 of 15
It is important to stress here that the nutrient medium must provide a carbon source such as sucrose and also inorganic salts, vitamins, amino acids and growth regulators like auxins, ______ etc. By application of these methods it is possible to achieve propagation of a large number of plants in very short durations.

This method of producing thousands of plants through tissue culture is called micro-propagation. Each of these plants will be genetically identical to the original plant from which they were grown, i.e., they are ______ .
