Problems in Crop improvement in INDIA (Author: Prashant B. Kale (Ph.D.))

Crop improvement involves various categories of problems

Author: Prashant B. Kale (Ph.D.)

1. Genetic and Breeding Problems:

1.1. Genetic Diversity: Limited genetic diversity can hinder the development of new crop varieties, making crops vulnerable to pests, diseases, and environmental changes.

1.2. Inbreeding Depression: Repeated use of closely related individuals in breeding programs can lead to a decrease in vigor and overall plant health.

1.3. Heterosis or Hybrid Vigor: Achieving and maintaining hybrid vigor can be challenging, as it often requires crossing two genetically diverse parents.

1.4. Genetic Barriers: Crossbreeding between species or genera can be technically challenging, limiting the expansion of genetic diversity.

A microtome is a specialized precision cutting instrument, which accurately and repeatedly slices sections from a block of embedded tissue. Different kinds of microtomes are used to section paraffin and plastic-embedded tissues as well as the specialized microtomes used to section frozen tissues.

In the case of plants, microtomy is used to prepare thin sections of plant tissues for analysis, particularly for microscopic examination of cells and sub-cellular events. Basic steps for creating microtome sections for plant tissue analysis are explained as: (figure: microtome and cryotome instruments with important parts)

Materials and Equipment:

1. Plant specimens
2. Microtome (a specialized instrument for cutting thin sections)
3. Embedding medium (e.g., paraffin wax or resin)
4. Razor blades or microtome blades
5. Glass slides
6. Microscope
7. Staining solutions (optional)
