Hint: The different kinds of crop resistant varieties of the different plants that were developed by the Conventional breeding methods to grow against the action of their respective pathogenic diseases.

Step by step answer:Pusa Komal – The Pusa Komal is the modified form of the Cowpea. This variety was developed resistant to the Bacterial blight which is a Bacterial disease. It is caused by the bacteria Xanthomonas axonopodis pv. phaseoli. It caused the infection on the leaves causing its yellowing.
