Title:- Project on Natural Disease Resistance in Plants.
And there should be evidences of recent advancement.
Description of Microorganisms infecting plants and their effect should be stated by taking atleast 3 examples of different category of plants ( For Example: Cereals, Ornamental, Fruits or vegetable crops )
Expert please give some idea how to make project .
This is a creativity based question hence it should be attempted on your own.
However, I am providing you with a few points that shall help you with the project.
You need to find examples of microorganisms affecting plants such as specific types of bacteria, virus or fungi that causes diseases in plants. You need to mention the
disease that each Category of microorganism caused in plants as well the symptoms.
Natural disease resistance is inculcated in plants by plant breeding techniques using the following steps:
-
Collection of genetic variability
-
Genetic variability is availed from the wild relatives of the crop.
-
Hence, all the wild varieties and relatives having disease resistance are collected and preserved. These natural genes available in a population are utilised by this method.
-
-
Evaluation and selection of parents
-
From the available genetic variability, the germplasm is analysed and evaluated to identify the plants with disease resistance.
-
-
Crop hybridisation among selected parents
-
Two selected parents are crossed (hybridised). This facilitates the combination of desired traits from two different plants.
-
Pollen grains from one plant are dusted over the stigma of the other plant.
-
-
Selection of superior recombinants
-
Among the hybrid progeny, those plants are selected which have the desired character combination (disease resistance).
-
Careful scientific evaluation of progeny is required for selection.
-
This step yields the plant that is disease resistant.
-
-
Testing, release and commercialisation
-
Selected plants are evaluated for trait disease resistance etc.
-
These crops are grown in research fields and their performance is recorded under ideal conditions.
-
This crop is then grown by farmers at several locations, for at least three growing seasons.
-
The crop is evaluated by comparing with the best available local crop cultivar (which acts as a reference).
