Question

Role of cytogenetics in crop improvement

Answer 1

Cytogenetic manipulation of the chromosome complements of crop plants is one of the most important methods available to plant breeders for introducing new variation into varieties of crops. Molecular cytogenetic analysis of the chromosomes of crops is a vital part of understanding their evolution, genetics, genetic recombination and karyotypic stability. 

Some aspects of Cytogenetics in crop improvement are given below:

1. Detecting and characterising alien chromosomes or chromosome segments in plant breeding lines with chromosome segments of various origins.
2. Developing markers for characters of interest to plant breeders.
3. Understanding physical chromosome behaviour, chromosome elimination, evolution and gene mapping: finding where genes and DNA sequences lie along chromosomes and within the three dimensions of the interphase nucleus.

Answer 2

Role of cytogenetics in crop improvement

Explanation:

• The cytogenetics is a part of cell biology, which is related to the chromosome behavior that takes place between the ng mitosis and meiosis. It has a  marked correlation with genetic traits.

• Molecular analysis of the cytogenetics in the chromosome of crops is a vila part of understanding the evolution, genetics and recombination and karyotypic stability. And it is still the most important method of plant breeding and the introduction of a new variant.

• As the genes form the wild species that can be chromosomal manipulation.  Some other recent advances include the chromosome banding techniques and the isozyme analysis, and the cytogenetics that play a vital role in crop improvements.
