Describe the mechanism of crop variety improvement.

Answer :

Crop Variety Improvement involves recognizing valuable traits and incorporating them into future generations  so that the future generations of crops give better yield and have natural resistance to disease. It involves the manipulation of crop plants in order to get better performance out of them

There are different mechanisms for crop variety improvement. The 2 main mechanism are discussed below:-


1.Hybridization - It is referred to as crossing of two genetically dissimilar plants to produce a hybrid variety. The crossing can either be between two different varieties known as intervarietal cross breeding or between two different species of the same genus known as inter specific cross breeding or between two different genera known as intergeneric cross breeding.This method results in hybrid variety that has the desired characteristics of both parents.


2.Genetic engineering - It involves producing genetically modified species by altering the gene code of the plant or by introducing a desirable gene and getting the desired results.
