Hybridization

1. HYBRIDISATION IN CROP PLANTS

2. INTRODUCTION
Is the food produced p.a. in our country
sufficient to feed the ever increasing
population?????
certainly a big “NO”
Thus, there is a need to enhance our
Agricultural efficiency.

3. WAYS TO ENHANCE AGRICULTURAL EFFICIENCY
a)Cultivate more land
b)Achieve higher yield on currently cultivated land
c)Restore the productive capacity of already degraded
agricultural land
d)Reduce wastes & losses in production processes.
Here I stress upon achieving higher yield on
currently cultivated land, which is possible only by
CROP VARIETYIMPROVEMENT.

4. CROP VARIETY IMPROVEMENT
 Refers to finding a good variety that would be superior in quality & giving
good yield.
This is done by HYBRIDISATION

6. TYPES OF HYBRIDISATION
Basing on the taxonomic relationship of two parents, Hybridisation grouped into 2
types
