Justifications for the development and use of MAS in plant breeding fall into four broad areas that are relevant to almost all target crops. These are: a. Traits that are difficult to manage through conventional phenotypic selection because they are expensive or time consuming to measure, or have low penetrance or complex inheritance. b. Traits whose selection depends on specific [...]
After reading this article you will learn about the meaning and system of plant tissue culture. Meaning of Tissue Culture: Tissue culture is a term, used to indicate the aseptic culture in vitro of a wide range of excised plant parts. It is used for both propagation and modification of genotypes (production of somaclonal variation and double haploids), biomass production [...]
In this article we will discuss about:- 1. Selection of Disease Resistant Variants at the Plant Level 2. Selection in Vitro with Toxins and Culture Filtrates against Diseases 3. Selection for Resistance to Drought and Flooding 4. Selection for Salt Tolerance. Selection of Disease Resistant Variants at the Plant Level: One approach to utilise somaclonal variation is to screen regenerated [...]
