In this article we will discuss about the significance of haploids. Application in Crop Improvement: Productions of homozygous pure lines are the major goal in breeding strategy. These are obtained by back crossing and inbreeding. These processes are however, are time consuming. Once established, homozygous lines have potential for plant improvement in several ways. With the advent of anther culture, [...]
In this article we will discuss about the role of auxins and cytokinins in culture medium. Effective, speedy growth and desirable morphogenesis in tissue culture requires the presence of both auxins and cytokinins in culture medium. The relative concentration of auxins and cytokinins are often essential to bring about some kind of morphogenesis. Axillary shoot proliferation in some species may [...]
The following points highlight the six main screening strategies that are to be enforced for the selection of ideal somatic hybrids. The strategies are: 1. Microscopic Visual Selection 2. Auxin Autonomy 3. Chlorophyll Complementation 4. Biochemical Selection 5. Verification by Molecular Screening 6. Chromosomal Analysis. Strategy # 1. Microscopic Visual Selection: It is based on the fusion between coloured and [...]
