In this article we will discuss about:- 1. Methods of Micro-Propagation 2. Stages of Micro-Propagation 3. Advantages 4. Commercial Uses. Multiplication of genetically identical copies of a cultivar by asexual reproduction is called clonal propagation. The in vivo clonal propagation is often difficult, expensive and even unsuccessful. Tissue culture method offers an alternative way of clonal propagation which is popularly [...]
In this article we will discuss about the methods of plant breeding for disease and pest resistance. Plant Breeding for Disease Resistance: Crops are required to be disease, resistant, as a wide range of fungal, bacterial and viral pathogens that affect the yield of cultivated crop species, especially in tropical climates. Resistance of the host plant is the ability to [...]
The following points highlight the five main steps involved in breeding a new genetic variety of a crop. The steps are: 1. Collection of Variability 2. Evaluation and Selection of Parents 3. Cross Hybridisation among the Selected Parents 4. Selection and Testing of Superior Recombinants 5. Testing, Release and Commercialisation of New Cultivars. Step # 1. Collection of Variability: Genetic [...]
